This might get locked, but i wanted to say thanx to everyone who has supported my idea on modifying a 305 TPI, Im finally done, after countless hours of going through pep boy,strauss,GM,Autozone, im finally done. At first the car sounded gay, but after 20 minutes warmup in break in period i revved it up to 3000 rpm car sounded like a roaring tiger, I really cant express my thanx to everyone, for making my dream come true,
THANK U

 

Glad to hear that your countless hours of frustration finally paid off. Keep us updated on tracks times and such..I'm anxious to hear what it does.

lol looks like ur the only one whos interested in seeing the last results bran

 

Did you build a new one from the ground up or tear down and rebuild what you had?

 

I'm interested in the results! Maybe I've been all wrong about 305's.

 

Im interested in the results, I built up a 305 as well. I raced my friend who runs 14.5s in his el camino, and I was far far ahead by 70, I should be into the 13s easily.

 

i'm very interested seeing as how i want to keep my 305 just so i can be able to say "its just a little ol' 305 tuned port"

also what have you actually done since i can't recall what it is you did to your 305
thanks
Andrew
