Sittin' here doin' my best Whyle-E head scratch thinkin' of what to do to my Bac-a-ruda to capture a 10 second time slip; best to date has been 11.14sec at 116.88mph; best 60ft has been 1.527, averaging 1.55.

The catch is I don't want to make any BIG changes, engine combo is: 360+.03 KB107's internal ballance, MP 557 installed on the dots, measured 2 degrees advance, left it there didn't want traction problems from pushing the torque curve down, M1 intake, 750 DP, Hughes CNC stage 3 ported Eddy's and Hughes 1.6 roller tip rockers. Other than 1 jet change (picked up 2 1/2mph) the engine is as built, haven't done any other tuneing/adjusting. Doug Thorley "D" Dart headers.

Tranny is a John Cope (thank you John) built 904 with a low first gear set, reverse manual valve body. Converter is a PTC that stalls about 5000 rpm. Rear is an 8 3/4 with 4.88's, tires are M/T 275/60/15 drag radials on Weld lites.

90/10 MP shocks up front, Cal-tracks (bottom hole, 1 turn(I think) pre-load, Mono leafs with 3/4 inch inboard relocation, Comp Engineering 3 way adjustible (set in the middle) shocks.

Car weighed 3030lbs with me in it.
I cross the stripe at about 7000rpm.
I stage at about 2000rpm, and flash the converter, I've got a zero spin, dead hook, pulling the wheels off the ground launch.

Things I have to work with/willing to do: 850 Demon DP, gear sets of 4.30 and 4.56. I'm willing to change tires (they are a consumable), but I can't go wider than 9 inch, I don't have the room. Should I go taller, or shorter? I will not consider NOs; I can't afford the learning curve. I am doing some additional weight reduction, gutted doors and quater glass removal, the rest of the interior is long gone.

I'm kinda thinkn' that maybe the 850 might help, but I'm not seein' anything that says 750 CFM isn't enough. I'm also thinkin' that maybe a switch to 4.56's (keeping the M/T's) might help, I know mile-an-hour will pick up; should I expect to see a drop in my ET?

I am pleased as punch, happy as he*l with my 11.14 slip, but I can't beleave I've already gotten all this combination has to give, I'm not that smart, that talented, that experienced to have hit the nail so hard, so square the first shot!!! The car is as built, out of the garage, and onto the trailer nothing touched save for a tire air pressure adjustment. Half the build of the car was mistake recovery!

Let me know what you think.

Thanks,

Jim Burch

Stuff I might try would be the 4.56 or 4.30 to start, maybe go all the way to 4.30 as you have plenty of low gear ratio and plenty of stall already. Easy to do. Next would be to tighten up the lash (intake first, and don't be afraid to go down .010)and see if it wants more cam, add collecter extensions if you don't have at least 18 inch. You can experiment with final length. Try more fuel, more or less timing after you get the fuel curve done. Advance the cam, after everything else is done if you want to see what it will do. Check your cold air intake, make sure it has decent air entry at the carb, also need to do back to back tests to be sure it is an improvement. You could try a real drag radial slick if you can get one in there, might want to match it with a small radial up front. Check around and see who is running hotter cams and going faster than you, to get an idea what you can get away with if you want to upgrade to a bigger stick. well, I'm getting brain freeze, hope this keeps you busy for a while!

with alot of what Greg said but I would
stay with the gear you have for now... try more carb
and work on the suspension... loose front end shock
setting and good rear shocks. The header extensions
will most likely pick up some torque

It is a learning process, what works on one car for one racer may not respond the same for another racer different tracks and different weather make different results Don't be afraid to experiment, make sure you have enough fuel delivery by jetting the carb up fat enough to make the car slow down the MPH in the 1/4 If you can't do that fix the fuel system and do it again until you can slow the car down by making it to rich Lots of things affect the car and the motors performance, stall, shift speeds, air pressure front and rear and so on. I have seen using a air cleaner base only pick cars up .03 Let us know what you do and the results

My initial impression is the combo is working pretty good.

To start with I would head to some test and tune sessions and work on the tune-up to see what it likes:
- vary jetting up and down until it slows down and go back
- vary ignition timing from 32-38
- vary shift points by 200 rpm increments, 6000-6800
- vary stage rpm 2000-3500

I am not a fan of 850 carbs, the transition and initial hit can be tough to get working; but it might help with CFM. Easy to try.

I would try the 4.56 gear also, but I don't expect much change. If you put taller tires on, the 4.88 may be better.

There are better cams out there, if you want to go that far. But you are in the right ball park, IMO.

Don't know what ignition timing you are running. Although I am not a fan of a lot of spark lead that combo will probably want 32-35 degrees. If it has a dome piston it may want 36. Just not familiar with that cam or piston.

I have ran the same car 65 Barracuda for 20 years now. Been a long time sense it had that suspension. The first thing that caught my eye was those boat anchor front wheels. I realize you probably still have the 4" bolt circle so that limits availability for alluminum wheels. Just for info you can use 73 and later A-body spindle and brakes as long as you get the upper control arms too.(The ball joint is bigger) Or if you want to spend some money the Wildwood front brake kit will shed quite a bit right off the batt. I picked up some real noticeable numbers with the wheel change and then a lot more with the lighter brakes. You would also probably be able to throw out the low gear set in the tranny when you do this. I know the low gear sets have a lot of popularity in heavy cars but your combo seems to be fairly light for that car. I ran the high and low gear sets and noticed the low gear set can be a tradeoff.

It would be nice to know all the incremental times of your car to maybe see if there is a particular area that needs work.

Good luck with it.

If you have the bucks try holeshot wheels... I think they will drill a 4" pattern for you....
your car run's good main thing I think your lacking is 60' and 1/4 mph my car 60's 1.47-1.49 1/8 7.0's 94-95mph 1/4 11.13 118mph... your car really pulls in the middle compared to my car... we need to race heads up LOL

Everyone, thanks for your replies.
More carb tuning, ignition (currently timing is 34 deg, all in by 2600 rpm), valve lash are things I will go after. Is plug gap something to experiment with? Currently .035, I run an MSD 6AL, chipped at 7400rpm, and the coil from Locomotins old MP ignition system he used to run.

I kinda think the 4.56's will be the sweet gear set for the 1/4 mile, though I'll leave the 4.88's in for the 1/8th mile (home track is Skyviewdrags, 5 miles from my drive way).

I know there are better cams out on the market than what I have in there now (it fit my budget when I bought it), and I very well may change it out in the future, at the moment I don't want to get involved climbing inside the engine and comming up not being ready for the season, (I know this is December, but I lost this year to fixing my Areodynamics by oxidation and I started in late January early Febuary) plus... I think it can deliever the goods. It's only gotta do it once.

Mr. P Body, you mentioned a looser front end; as in aluminum/solid nylon bushings? Several years ago (another summer I lost to car construction) rebuilt/rebushed/replaced the complete front end with a 73 disk brake set up. I could make solid bushings and I do have another set of 73 to 76 upper control arms, I could have them waiting for a good time to make the swap.

I guess front wheels are kinda heavy, they are dognut spare rims, VW bug spec tire, the least expensive 4 inch wide tire/rim combo I could come up with at the time. I inflate the tires to 50 psi.

Here's a couple of my time slips:

i am just thinking out loud here..
looking at the first and second time slips..
the first time slip had colder weather..
thinking this colder weather making your normal tune a little lean....
showed..a slower 60ft..
but more mph and quicker et..

the 2nd slip..assuming not as cold..so tune was less on teh lean side..
the car 60fted better but
mph and et where down..

my experience the launch likes fuel..a lean lauch will be lacking..

a fatter launch will give you good 60ft..

the same tune in the cold weather acted leaner up top..giving you a better mph..

you might try the mph and et from the 1st slip
and the 60ft et of the 2nd 2 slips

combine a little more fuel at launch and keeping it clean and lean up top might get you there..
just thinking out loud...

Thank you all for your kind words.

Cheepstreet,

The major reason for the difference in 60ft's is track prep. The day before it was under water, so I'm not gonna worry a whole lot about the differences.

I'll work on fattening up pump shot. Thanks.

lighter thinner front wheels and tires.
get 141 lb total out of it!! LOL!!
Shift point
the bigger carb will pull much better 330 feet to the 1/4.

I saw the word budget a couple times. I agree with the basics that everyone mentioned. I would exhaust all options first using what you have without introducing any new parts and play with timing, jetting, tire pressure, shift points, and suspension adjustments (a benefit of the Cal tracs). Will only cost you your time, fuel, and entry fee. You can dig in a little deeper after that with advancing the cam, gears, etc. Shoot, if you know enough racers up there, you can see if anyone has a carb or something you could try rather than rolling the dice and throwing down the bucks for something that may not change anything, or worse... slow you down!

Oh yeah, are you using anything electrical like fuel pump, water pump, and running with or w/o an alternator? Some power might be gained with a different intake too, or some work done to the one you have if nothing was done to it, but would leave as is until you have tuned everything you have now.

jim, project (no buck) (low buck) sure is running great.i remember the 1st time i seen your car,it was at the old shangri-la when we were running,the front stretch of the oval track,im willing to lend a hand at the track,for any help u might need(except money)hehe,see u in april.mike d.

You're actually in pretty good shape so far. You're within pounds of my 69, with a very similar combo. A couple of things come to mind, though. Put a bigger fuel pump on it and make sure you have a big enough line. You need to be able to fill a 1 gallon jug in 15-20 seconds from the line going from your regulator to the carb. Secondly, as someone has already pointed out, put some lighter wheels on the front. Remember, you are accelerating these tires from rest to several hundred rpm in just over 11 seconds. That uses up considerable HP, actually.
I've discussed the low first gear thing at length with a guy who builds stocker motors for a number of national record holders. He's not a convinced it's the right ticket on a stock stroke bracket car. You and I run several mph faster than a 11-teen stocker. This means that low first gear puts us in 2nd and 3rd for a greater period of time and probably hurts more than it helps. Our big drawback is that our 360 inchers are a bit "torque challenged."
On the bright side, you're literally a handful of tweaks from a 10 second time slip.
I'd put the 4.88's in it. My 360 had been pulling 7100 in the lights before I went to a looser convertor that somehow quickened the launch but has killed the MPH and ET by 3/.3 with a lower trap RPM to boot.

I had'nt considered the fuel pump (it's a Holley blue), I could paralell two I suppose.

I like your reference to stock eleminator cars, they may not mile-an-hour real big (depending on class), but they ET like crazy and that impresses/motivates the daylights outa me.

I'd like to here more of your thoughts about why not to use a low first gear, gear set.

Mike, I welcome any help your willing to give. Look forward to seeing you at the track.

Do you remember this seen?

put a one inch open riser under the carb. that should make a big difference. easy , cheap, and effective.

I had'nt considered the fuel pump (it's a Holley blue), I could paralell two I suppose.

I like your reference to stock eleminator cars, they may not mile-an-hour real big (depending on class), but they ET like crazy and that impresses/motivates the daylights outa me.

I'd like to here more of your thoughts about why not to use a low first gear, gear set.

Mike, I welcome any help your willing to give. Look forward to seeing you at the track.

Do you remember this seen?

Before you spend dough on a fuel pump, put a fuel pressure gauge on it and determine if it NEEDS it. Also, the fill-the-bucket test is good, too. I KNOW of 8/9/10 second cars with ONE blue pump. Make sure the delivery is good (1/2" line, no sharp bends, etc) and you should be good.

Comparing your car to a stocker is apples and oranges. They have aluminum drum, roller bearing trans, light spools, rifle drilled axles, moved wheelbases, 51%/49% weight bias, lightned cranks, etc...

There is probably a SOLID .10 in your front wheels and tires. A RACE front runner is light! Every so often you see small bolt pattern Centerlines for sale on here and foraboldiesonly.com

Good luck and keep posting the updates, cuase my low-dollar 360 Dart project is underway!

You're actually in pretty good shape so far. You're within pounds of my 69, with a very similar combo. A couple of things come to mind, though. Put a bigger fuel pump on it and make sure you have a big enough line. You need to be able to fill a 1 gallon jug in 15-20 seconds from the line going from your regulator to the carb. Secondly, as someone has already pointed out, put some lighter wheels on the front. Remember, you are accelerating these tires from rest to several hundred rpm in just over 11 seconds. That uses up considerable HP, actually.
I've discussed the low first gear thing at length with a guy who builds stocker motors for a number of national record holders. He's not a convinced it's the right ticket on a stock stroke bracket car. You and I run several mph faster than a 11-teen stocker. This means that low first gear puts us in 2nd and 3rd for a greater period of time and probably hurts more than it helps. Our big drawback is that our 360 inchers are a bit "torque challenged."
On the bright side, you're literally a handful of tweaks from a 10 second time slip.
I'd put the 4.88's in it. My 360 had been pulling 7100 in the lights before I went to a looser convertor that somehow quickened the launch but has killed the MPH and ET by 3/.3 with a lower trap RPM to boot.




Yea, I think your car's light enough not to need the low gear. Plus, with it you're leaving on mechanical (gear) leverage rather than the converter. One thing I would try first, is the 4.56's rather than the .88's.

One thing to do, is change ONE thing at a time. Also jet up and down, timing up and down with any gear/carb/cam timing change to determine what it likes!
