I still wouldn't look to get out of the 16 range by much if any but thats just a guess.

You could run Giggle Gas or maybe a procharger.

Sounds like an exercise in futility to me, like sending in a boy to do a man's job. Stop wasting your money.

hmm sounds intresting. If i had a 305, id do some head porting, a different cam, 600 cfm carb.. Lets face it, it wouldnt be all street friendly. Itd have to rev so much to touch 350 hp... More cubes would make a more street friendly power to cubes ratio.. I think you would actually change times with the 350 4 barrel and headers.. And id then expect to see some 15s and maybe some high 14s with slightly hotter camshaft. Thats just my opinion.. But for stock, gas milege, a 305 would be good

i agree, but i think the key here is to try to have fun on a limited budget. i think i may re-channel my racing plans to follow suit.


1) i would first find out what rear diff gear you got; i think this makes the most difference(for the least $$$) when you are first starting a project.

2) i'm not sure why you have a 2000 stall converter with a stock 305? Explain.

3) i love corvette rallye wheels, but they are relatively heavy---not the best thing for racing. i would instead suggest, as a cheap alternative, 80-81 z28 wheels--or newer z28 wheels in general---iroc etc., or 85-88 monte carlo ss wheels. Very light and can probably be found on craigs (love that guy) or the salvage yard. This will probably make a big difference.

4) The removed wheel wells will cause turbulence and can actually slow you down.

Is the stock ET of 16.6 something you drove it to, or a figure found online or in a magazine? Don't be offended by this but judging by your modifications, I honestly would not be surprised if the car went slower. Let us know how you run when you make it out there.

i think 16.6 is possible stock depending on rear gear. i think 17's is more likely though.

My truck runs 17.9 with a stock LG3 305 with 2 bbl.

A man and a boy both try to build a tree house... The man does a better job, the boy has more fun. Who's the real winner?

Everyone starts somewhere. If his goal is to have fun tinkering with simple mods and bolt ons, while he learns more about going faster, I say go for it. He seems to have more realistic expectations than most folks who think an intake and cat back will shave 3 seconds off their 1/4.

That being said... to the OP, when you're ready to make significant changes to your speed goals, this board has some great master jedi to learn from, including TechInspector.

Now go put a 100HP shot of giggle gas on that sucker!

REVISED:

3) You can't put camaro or monte carlo wheels on an caprice---different bolt pattern. Sorry. You might try 94-96 impala ss wheels?

It's all a waste depending on the perspective. Some would consider a perfect 10 car that can run consistent 10's in the 1/4 as a waste for one reason or another. We do it because it makes us, the spender of the money, happy.

If trying to reach a 15 second pass in the quarter makes the OP smile, perhaps it's mission accomplished.

I say go out and have fun, maybe you will break into the 15s.
When you get the chance look into a 350 or maybe a 327 or a 400?
