I thought thats where the 13.2 second time came from. For a 3600 pound chevelle that is awesome in my opinion. my car weighs at best 2300-2500 pounds. Thers not much to it... fiberglass hood (or no hood at all), plastic bumpers, no interior, smaller fuel cell, no ac system, no heater box, no actual dashboard, nothing under the dashboard, no wipers, and an air freshner.

13.2 seconds is good enough for me... maybe a little lower maybe a little higher. It would be a start at least.

Low 13s is impressive on street strip cars to me!! especialy on your first build when your young and learning! As time goes by you can tweek it! Change things and have fun doing it! Building a killer fast sometimes isn't as fun as the slow approach when your young! We (sorry I should say I) have fond memory's of my early builds, swap meet finds, buddies helping, using a newspaper delivery box as a scoop, water pipe cut outs with caps home made steel packs, Firestone recap slicks (yes some slicks were recaps back then), running low 13s and tweeking in the pits and running in the 12s on the next pass . A little 283 with a tunnel ram, 2 600s with the chock horns milled off , 202 power pack heads , General Kinetics cam (Ground at his garage in an alley in detroit), ram horn manifolds with just the header pipe, M22 4 speed, 4.11 gears (57 chevy housing), in a 50 ford junker LOL and running 13s at Detroit drag way when I was in my senior year 17 years old, I had 2 paper routes Detroit Free Press at 5am in the morning and Detroit News 3pm after school, and a 2 hr a day job sweeping a body shop after they closed at 5 pm. and spending all my money for cigarettes, premium gas, & burgers & fries and cherry phosphates on cruise nights at Dog & suds!! all the rest ($) went to parts for the 50 ford and every week it went just a little faster! If I had the money to build a 10 or 9 second car all at once I would have none of those old memmory's and the fun!

Theres nothing wrong with building slow and using what you can afford and have laying around! You can always upgrade as you go!! Last year I bought a brand new Weiand high ram still in the box for 100 dollars. So you can build cheep if you look around! I ended up running high 11 with that 50 ford before I joined the service! with that same 57 rear and a 4.88 gear among other changes,And beat guys with the ford 9" nodular! A lot of things work very well and you could be ridiculed for running LT1 202 camel hump heads but those heads helped me run 10.3 at 131 M.P.H. on a 327, mickey thompson cross ram with 2 950 Holley 3 barrels & Black jack headers borg warner liberty geared 4 speed and same 57 rear end and casler 10" slicks!! On a 2300# car !! I had a lot of fun LOL !

To answer Matts post:

Quote:
i think you need to start over (in this thread)

heres what i want to accomplish
No brainer - i wanna go fast. As fast as i can within reasonable limits. Im not planning on breaking 10s so if 13s or late 12s are feasible - thats my goal.

Quote:
heres what i have
I already mentioned what i have, but for a recap:
-350 4 bolt main block bored 030 over =355
-keith black pistons (P/N UEM-KB193 030) dished, two valve reliefs, +12.oo ccs
-a (pretty sissy) summit old cam :454lift int and ex, 216/216 int /ex @.050, 272 duration, 112 lsa
-trickflow twisted wedge heads (P/N 31400001) 170cc intake, 63cc chambers
-9.8:1 compression
-Weiand high ram with dual holley 450s (unaltered carbs)******
-rest of the drivetrain will be beefed accordingly

Quote:
heres my budget $$$
No set figure. I can swing a few hundred a month.

Quote:
whats my best way to spend my $$$ to get as close to my goal ?
do everything in moderation?...

If i can find a better cam, and play with the carbs, while using the rest of my engine to get my car to pull 13s - that would be fantastic.

****** Also - the T-ram setup is expendable. Let's say i have a good friend thats willing to buy my setup (T-ram intake and both carbs) at their original cost - approximatley $750, if the need to go to a different intake / carb setup should arise. If something else would be better suited for my setup so be it. Thats why Matt found my other post. I basically found what the Holley wild street setup would come with.

As always - thanks-a-million everyone

the carb or carbs will need to be tuned for top performance anyway, no matter how many you have
you will be able to make it work
these guys know their stuff

sounds like maybe work with what you have, get it tuned correctly
spend your first batch of dollars on a converter and some rear gears

what size were the headers/exhaust?

1 3/4 primaries 3" collector, longtubes, most likely 45* dumps to come out of them. If not - duals with flowmaster 40s

look at the most powerfull old Ford FE motors (390-406-427-428) they all came with dual quad hi rise manifolds and big dual carbs.
the 427 tunnel port nascar motor had a tunnel ram manifold and two big carbs.
tiny carbs kill any of the dual quad manifolds including the tunnel ram .
its all on the combo.
I think that post was some troll action

big bad 390 fe hey man a tunnel ram doesnt gain much ponies but look cool.
You obviously havent read any of this thread. But i do appreciate your enlightening insight and advice in the world of tunnel rams and high performance.

It would be real nice to shave off about .040 .050" off those ehads and use a thin head gasket to get the real compression ratio up to snuff.

This also moves the valves closer to the pistons and needs to be accounted for VTP clearance. The real compression ratio is not goig to be even close to 9.8:1 as the block is most likely not a true 0 deck . The chamber volume probabily is not at spec either. i bet its barely 9:1 actual.

-12 cc D dish pistons. stock ish deck clearance .025"+
typical 9cc ish .040" + gasket

Port flow can be improved with some hand porting.

its all in the details.
It's actually pretty close to the value i stated (9.8:1). It may actually be more - when i did the math, i actually forgot the actual thikness of the head gaskets i used so i used a higher value. And i'm pretty sure i can go bigger camwise, but i mas making pretty good vacum before with that cam, so i may keep it for just a little bit.
