Just for fun...what will it run? UPDATE!!! Results!!! - 05/17/11 03:59 PM
Taking to the track for the first time this Friday. Have no idea what to expect, but is WAY more than my dad or I have ever experienced from a little street driving, and we still haven't dipped into the secondaries. It ran low 13s/very high 12s with the low compression 340 before. Probably going to take it easy and shift at 5000-5500 this weekend since it's a new motor.
69 Cuda. 3500 lbs with driver.
418 stroker 10.3:1 comp
Fully CNC'd Eddy Heads from Hughes.
Ported Airgap intake.
248/252 .600/.610 solid cam
Holley 750 modded to flow 910 CFM
MSD E-Curve dist with 6-AL
TTI torque stepped headers w/ Ultra Flo mufflers
3:91 727 Tight 10" converter.
M/T drag radials 275/50/15.
Stock suspension.
Very little tuning to dial it in as we just fired it Sunday for the first time. Don't strain your brain over it, just looking for ballpark. I'll update after this weekend.
Mid/low 12s? High 11s?
Thanks to all who have helped us get this far.

I ran 10.95 at 121 with a 1.56 60ft a couple weeks ago.
I have a little less compression and more carb but pretty close combo
My chassis also seems to be working well
My conveter is more of a nitrous conveter also
I would figure you should be low 11/s maybe high 10's

Re: Just for fun...what will it run? - 05/17/11 04:25 PM
Just last week a friend had a very similar combo out. With only 1.80 sixty (traction issues)went 11.89.You should go low twelves on your easy runs and eventually high tens low elevens when sorted out.

Re: Just for fun...what will it run? - 05/17/11 05:20 PM
First time out 11.30's - 11.60's. Once dailed in and tuned well mid to high 10's are within reach. Good luck , Ron

Car is pretty heavy. If that weight is accurate and the converter is on 11.40 - 11.50. Tune it up and 11.20 - 11.30 is within range. I think you'd be hard pressed to get 10's out of the combo the way it sits. You don't have much for a converter, gear or traction so you'll be limited. You also didn't say if this will be full exhaust and what size or open headers. In fact if it's through a full exhaust 11.70 is probably going to be the best you can expect.

I am running TTI headers and full 3" exhaust with an H-pipe Ultra Flo mufflers. Do you think that free flowing exhaust would slow me down by 4 tenths?

Re: Just for fun...what will it run? - 05/17/11 11:28 PM
Id say 11.70,s if the vert isnt To tight and the suspension works. You stated Tight vert, do you know what its rated at.
That stock untested suspension with the new combo may keep it in the 12.20 range for starters.
Posted By: Streetwize
Re: Just for fun...what will it run? - 05/17/11 11:38 PM
11.70-ish, but why is it so heavy?? Not a lot of gear, either but your torque should make up for that.
Weight transfer is key with a big torque motor in order for it to ET.
Combo sounds like it should make about 500-520, should push you to right at high 1-teens or so.
I have a loose 10" T/A that I might trade ya, I think it would work better for your heavier lower compression combo....mine on the other hand (12:1, 550+ horse/2900 pounds/85" WB/4.56) might be a bit tamer off the line with a tighter vert
For 1/8th mile ET bracket racing I figure I might just launch in second and not even have to shift for the whole 660', It wouldn't be as quick.....but it'd sure be quick enough in a first leave situation and be consistent as all get-out

Re: Just for fun...what will it run? - 05/18/11 12:09 AM
You should run mid 11s easily! I think once dialed your combo is probably a 10.9 second combo.
Posted By: OA5599
Re: Just for fun...what will it run? - 05/18/11 02:33 AM
Do you think running open exhaust would make much of a difference? @Wise: curious to see how this converter works first. Car sees 95% street duty, so I hate to go too loose with it. But I might consider that down the road. Hughes builds this exact motor fairly often, and with the port work they said 550+ HP and 500+ ft lbs.

try jetting up and timming too

Re: Just for fun...what will it run? - 05/18/11 03:05 AM
I don't get it.....I guess
That car should run mid 10's with ease. Had a W2 headed 378 with a mild port job that ran 10.68 20 years ago at 3400 lbs. You should have the torque to handle the gear and converter sense it is a 4.00" stroke. I ran a 4.10 gear with a 4400 TA 8" converter.

if it don't go 10.90s i would sell it, my old dart all steel hyd flat tappet cam and stock heads on a .030 over 318 with a 150 shot would go that and you got a LOT more motor than i did, even with the spray.

A 3" exh system with Ultra-Flow mufflers and a H-pipe slow you down 4-tenths ? No way that system will slow you down 4 tenths. If the pipes are mandrel bent I say a tenth at the most and that only because its an H and not an X pipe. Ron

Re: Just for fun...what will it run? - 05/18/11 05:02 PM
Thanks to all who responded. I guess we will find out this weekend. Would really like to see 11.80s or better out of it. I know my suspension, converter, and full exhaust will hurt me, but this is a street car first and foremost. I don't think anything in the 11s will be anything to be ashamed of. Most considered it a sleeper when it ran 13 flat.
Posted By: viperblue72
Re: Just for fun...what will it run? - 05/18/11 05:25 PM
I think you are going to be pleasantly surprised. Even with tight converter and full exhaust the only way you're gonna run 11.8 is if you get absolutely no traction. I ran a combo just like yours with full exhaust 3k converter in all steel duster with cage. Only difference is I had a
248@050 solid roller. Eventually got down to
11.0s.@122 and that was with a lusy 1.65 sixty foot.

Re: Just for fun...what will it run? - 05/18/11 09:09 PM
My guess is somewhere between 11.80-12 flat initially.
I had a pretty similar combo years ago in my duster( which at that time with me in in was 3450 pounds( bench seat interior, all steel and a 300 pound driver)cage, etc, etc.
Same headers, different muffs, 248/258 crane cam( way to little), airgap, 727, 4.10 gears, 3500 10 inch convertor, several different carbs, a little more compression, and similar eddies( mine maxed at 275 on the intakes, so likely not quite as good) the car went best of 11.69 at that time, with a lot of fiddling around with it.
I went with 8 inch convertor, fully ported heads, 260/266 flat cam, changed intakes, and raised compression,( 12-1) hair less weight and picked up a whole second the following year. Those saying you are going to run 10's with your current combo will soon see it wont, but you have a nice deal there, good luck. Should pull hard.
With that cam and compression, and other factors, hook, convertor, etc, etc, i suspect about what i sad above at somewhere around 113- 114 mph...
Posted By: Leon441
Re: Just for fun...what will it run? - 05/18/11 09:54 PM
Hmmmm....
My heads only flowed 265 and 180. Nothin killer there. Only 3.58 stroke so I had to turn it 8,000. You have a 4.00" stroke you can turn it considerably less. Your cam is close to what I had. Those eddies should be pretty good. Compression is not everything in my opinion. Flame travel is just as important. Your converter may be a power eating pig. If not I stand by the numbers I posted earlier. Mid 10's.

Re: Just for fun...what will it run? - 05/18/11 11:18 PM
Is the plan to really only short shift it around 5000 or so, like stated in your first post. If so that will handicap the ET,s
All you guys saying 10.5,s, you saw that shift point didnt you.
You couldnt have IMO

Your right, i take back my 11.80-12.00 thought, with that low of a shift point likely mid 12's
Seriously, though..i think that car , if its 3500 pounds, once sorted out extremely well could go mid 11's as it is, but high 11's at the point he is going to start at.
Takes a lot going on to get in the 10's, and with a not optimal convertor, gears, and a small cam( 4 inch cranks eat up a ton of duration) he has currently a high 11 sec combo.

Re: Just for fun...what will it run? - 05/18/11 11:37 PM
If your heads are flowing around 300 as stated that car on a good pass should get you a very low 11 or high 10 second pass. I have a 422 inch smallblock in a 3500 lb car and have had a best last year of 10.91 and that was in stupid heat. I hope for a little better than that this weekend.

Question...
Those heads are without a doubt good heads.
As you spent the money for them, are you planning at some point to use the potential they have, because the rest of your combo is more suited to just using cleaned up Eddies.
Not picking on you( not trying to anyway ) but you have more " head" than what the rest of your combination/intentions is going to use.

Re: Just for fun...what will it run? - 05/19/11 03:07 AM
I will guestimate 11.60 if you shift closer to 6500 dont quiet know why you would shift at 5000 to 5500 even on a new motor make sure you have enough jet and not to much timing and let it rip converter and suspension are going to hurt as you stated
Posted By: OA5599
Re: Just for fun...what will it run? - 05/19/11 03:49 AM
The shift point was to go easy on the new motor. But from all of the feedback I am getting, I think it will get shifted at 6500 from the get go. Just have a lot of $$$ invested and was trying to play it safe.

Re: Just for fun...what will it run? - 05/21/11 07:11 PM
so how did it run?
Id bet at 11.8 because of the fact that it is a street car.
What works on the roads dont work at the track.
Aldough 550 hp should get it ti go high 10s.
Tell us please.

60' 1.62
1/8. 7.32 @ 93.5
1/4. 11.52 @ 114
That was through closed exhaust all the way through A-Body tips.

Going from 13's to mid 11's is a nice improvement. And I bet it drives nice (mild) on the street. Sounds like what you were trying to do.
IMO, with only a couple changes for all out race, it could run 10's.

Way down on MPH for what you have. That thing should be clipping close to 98 in the 1/8th and 120 in the 1/4
Sounds like it ran pretty good. I don't get the babying it though, this ain't the 1960's when machining and rings were crude.
Keep at it, there's a bunch more in it.

Re: Just for fun...what will it run? - 05/22/11 05:53 PM
The 60 ft is pretty decent if you are stalling up to 2,000. I think you could pick that up if you allow the converter to work, after all it is a tight 10". Try leaving off idle. I mean make sure there is air between your foot and the pedal before matting it when the tree lights.
I have to agree about the MPH. A good converter would be locked up at the stripe. So that shouldn't be it. A carb too rich will not MPH and will definately leave lazy.
Hey, first time out with no problems. That's a plus. Faster than the cars has ever been another plus.
Want to go faster. Try my launch method. If the engine stumbles tune it. Install at least one new plug say in #1. Shut the engine off after safely passing through the lights and in your case slowing down to a safe speed. (After practice and learning your combo you can do it right after the finish line if you have manual steering and brakes) Carry a wrench switch out the plug or just look at it on top end if you wish. You should be able to identify if it is rich. It it looks rich swap a smaller jet in the carb front and back. You can try as much as 4 numbers. If the plug looks reasonable try just going down 1 size in jet. Your MPH will tell you if you are going the right way. MPH is HP don't care what anyones dyno says. Use MPH to tune the carb. You can even try timing again MPH will tell you the best to run in your car.
Good luck I see 10's in your future.
If I can help just ask.

Most important is that you had fun.
But when i jetted down my Dart (9.0!AF) i was 7.4 1/8 and went 6.9. so work some on the carb first if you want to go faster.

Re: Just for fun...what will it run? UPDATE!!! Results!!! - 05/23/11 07:31 AM
Wow thats great !
It runs right about where I do in my 63. Your 60's weren't bad for the combo. My best is 11.49 @ 116 with a best ever 60 ft of 1.57 but it was a 1.60 on the 11.49 pass. And my 1/8 mph is usually 93 mph so you have good #'s for that combo. I love 11 second street/strip cars you can drive around in. I hope mine becomes a 10 second driver soon. But you did great and the car ran great. Very nice job.

We ended up shifting at 6200-6300. Hit right around 5900-6000 at the stripe. Traction is an issue. It hooked hard on about 1/2 the runs. Hit the rev limiter a time or two also. Thursday night our Holley fuel pump started leaking due to a crack in it. The only option was to go with a stock fuel pump for the weekend, and I'm sure it didn't do us any favors as it acted like it was running out of fuel towards the end of the quickest run. I agree that it has more in it, but we are very happy with how it performed the first time out. 11.50s on a pump gas small block through full exhaust and street friendly was the goal, and we hit it.
Thanks to everyone on here who answered our countless questions.

Re: Just for fun...what will it run? - 05/23/11 06:47 PM
Wow that's a little better (.1-.2) ET than I expected....but then i figured your heads were more like 280-ish (like mine) and not 300cfm.
The et is very good for the MPHso the combo is working, I'm wondering if the intake may not be keeping up with the heads at the top of the range which hurts your MPH some, but all the same I wouldn't give up the dual plane's additonal grunt because it seems to be ET'ing on torque.
Nice job, buddy, and Nice car!
