Update....

Hey guys, well, its been a few years.. lol.. but, i finally got to the track. After a full bottom end rebuild,"old school style", and a few other mods since the original post i finally decided to see what my old rust bucket was capable of..
Of about 6 passes my best e.t. was 13.16 at 105.5 mph. I was actually very pleased and pleasantly suprised at how consistant the car ran. And most of all i had a blast!!👍👍

After my best pass i made some carb adjustments, i have an adjustable vacuum pod for my secondary circut.I adjusted the secondaries to hit quicker,then i started to spin off the line..🤔🤔 I need some better slicks than the used BFG drag radials I have currently.. then, i think i'll hit my 12.99 goal pretty easily. And it's up from there.. 😃Thanks again to all who posted suggestions.. all of them were helpful.😃😃👍

Any other new suggestions or advise would be great too.

I didn't see mention of you having a cold air system. That is well worth the effort. How about collector extensions if you drop the exhaust? I would try 18 to 24 inch extensions. Those two items alone could beworth more than two tenths ET. Pump the front tire pressure up some, every little bit helps. Be sure you have an excellent air cleaner base for best air entry. If your heat riser passages aren't blocked, do so.

Congrats. You should be hooked now.

The first thing it seems that everyone does after their first time out with some tire spin is to do better tires.

Here is a promise, you can do 12.99 with driving practice and tuning alone.

Not so much a coldair system, but i do have a functional R023 Belvedere style scoop on my steel hood. I keep my front skinnies at 30 psi.. would more be good ?
I wish i could run uncorked, but the track has a monitored db limit.. pretty lame, but, they didnt check for the db's at tech, so, maybe i could try it.. dont wanna get 86'd tho.. i do have my heat cross overs blocked.. and i run a 14"x4" K&N element.. should be plenty of flow.. thanks for all the suggestions tho. I run a pretty big drop base .. i may need to try a flat one if i can squeez it in. Need to cut a larger hole in the hood..

Seal the air pan to the scoop opening.

Leave the exhaust. Faster through muffs is better

Add jet until it slows down and go back down a size.

Does your 3310 have a secondary metering block? If not convert it.

If you add one step in jets and it slows down, go the other way until it slows down.

Once you find the optimum fuel curve, start experimenting with timing.

Get a log book and maintain copious notes. Change ONE thing at a time.

I PROMISE YOU, if the motor is remotely healthy you have a solid high 12 second ride with the parts that you already have!

Happy Hunting!

....and buy a weather station.

If you have room, you could put some race mufflers on the collector extensions. That might reduce the Db enough to allow unhooking the regular mufflers?
As far as how much air to run in the front tires, I am not concerned about running 10 to 15 more than what is on the sidewall. They pick up pressure as they warm up on the highway, so there is some safety margin.

I glad you had FUN. Fun gets you through the bad times and makes you enjoy the good times even better. God knows I love making passes

Thanks for the tips Cudadog, i do have a secondary metering block. When you say "add jet" should i just focus on the primary side first? Or try primary and seconary at the same time ?
I'll definetly be buying a log book,Holley jet kit and weather station before my next trip to the track.Maybe i'll try 40 psi in the fronts next time. Do you think 38° total is too much timing for a 9.8-1cr with iron heads on 91 octane ?
Thanks for all the solid info guys 👍👍

Just do a couple of degrees of timing at a time..
and look at the plugs.. as to fuel.. try 3 jets
at a time till you see it change(speed up or slow
down) do things in small amounts till you get a
handle on things

Should i focus on jetting the primary side first, then move to the secondaries ?
Also, i've been leaving off idle.. my converter flashes up to about 2,800 when i launch. I'll probably try running up the stall to maybe 1,500-1,800 next time.

I would do both primaries and secondaries together to maintain even fuel distribution throughout the manifold. I think bringing the launch speed up will help.

Its as simple as you say, get some new or good used slicks and your there, your 105.5 at 3740lbs computes to an on track 360hp and 12.77's with 60fts around the 1.77 mark, your tickets will show the story...once you have the slicks and its hooking good, you can bring those secondaries in early like before and also try more start line rpm and you'll be well into your goals and past it, once you have some time slips and a base with that tune, up jet the carb both pri/sec at 2>3 size increments until the mph drops off but there's only so far you can go with what I think is a small carb for that set up, 440's like air and lots of it.

Next step would be a good used 850DP Holley keeping costs down which would work well and even better with a looser converter (3>3200 as you have the cam) and perhaps at some time taller gears to get that weight moving quicker but still keeping it streetable and within your rpm range on track at the stripe..I could see it going close to mid 12's like that?.

On my best pass my 60' was 1.95.. so thats definitley where i can do much better.. i do have an 850 vac secondary carb.. it felt sluggish compared to my 750 with the proform main body.. so, i put the 750 back on.. i was gonna save the 850 for when I actually bite the bullet on some better heads.. 🤔🤔in reality the 850 probably just needs more tweaking to be optimized for my current combo. The 750 just feels so much better on the street..
A better converter is on my list too.. its just a matter of funding.. I'm leaning toward a 3500 Turbo Action.. but, i think I'll be better off investing in some better tires first.. thanks again all for the helpful hints..😃👍

"Old Heddman headers 1 3/4" primaries into 3' collectors into Flowmaster 40 series muffs that dump in front of the rear axle"




You might consider "straight through" type mufflers (at some point). Those flowmasters have some baffles in them that could restrict top end flow(mph). Nice job so far with only a 1.95 60ft!

My time slip.. 😕😕 so close.. yet so far.. still have a goal to shoot for tho.. 😊.. thanks pacifica.. so much fun!!

Just wanted to put a cap on this post. Finally got back to the track with a new converter 9.5" FTI 3600 stall. I ran out of fuel at 3/4 track due to my stock fuel pump. Bummed!! I upgraded the fuel pump from a 20gph unit to a 130gph mechanical unit. I also stepped up to 3/8" line.

Also stepped up to an 850 annular booster double pumper. It hits hard !! Woo hoo!!

M/T pro bracket radials 28x9". My next trip out it went 12.55 @107.75!! Totally stoked !! Thanks to all for all your helpful tips and info. All I can think about now is how to scratch into the 11's .. lol.. but that's another post.

Focus on the first hundred feet, the rest of the track will take care of itself, info shared with me by Joe Allread (RIP) circa 1976
Your on the right path to going faster by looking at the results, a lot of cars run out of gas around the 1000 Ft. mark and the owners, drivers, don't realize that
Focus on the time slip and spark plugs, richen the mixture up until it slows down, if you can't do that you have a fuel volume delivery problem, if you can you don't
TEST, Test ands Test some more
I won my first drag race trophy at the old Mickey Thompson Fontana Drag City in the spring of 1964, I have raced on the new track your on now also

Time slip from my best pass. I made 3 consecutive 12.50 passes.. 12.55,12.56,12.57. Pretty stoked..

Will clamping the front sections on my leafs help with my 60 ft ?? I just have the standard heavy duty leafs on there and a stock snubber.
