Now you need to get into tuning the Chip and get the engine the proper air/fuel ratio and timing advance.
Are you using 350 Vortec heads or 305 heads? If its un-milled 350 heads, you lost ALOT of compression.
i got the heads from jegs i think they are 350 heads. i wanted to get it tuned and all but dont know where is a good place near chicago i live about 45 min away. so is my e.t. bad or ok? what time should i have been doing?

Not to hijack the thread or anything but what size chambers do the 305's have? I don't really think I'll ever go with the expense of heads for the small motor but Edelbrock has a new budget priced aluminum head out that I'd consider.

yeah it might not do much now but im thinking of a super or turbo-charger for it. i wanted the 305 because it has a little different note than the 350 and everyone has a 350. ill be happy in the high 300 to low 400 hp area. dont need more power than that . any race you win you will laugh at your opponent as he got beat by a motor lesser than the mighty 350. with the 350 theres no excuse to lose. ive already beaten a few imports and they all think my car has a 350.

Horsepower and proper tuning is horsepower and proper tuning, whether it's a 305, 350, or a 4 banger. It is fun to beat guys who have bigger engines, when you've got your smaller engine hooked up properly.
My car ran that way with the stock heads and stuff, just with some longtube headers and msd box. should've had the heads milled to compensate for the lost compression
