i was wondering if anyone can give me an idea of how fast my car would be if i added these performance mods....right now i have an 89 350 with computer work done, shift kit, slp cold air, and slp cat back exhaust, and alot of suspension work....if i added headers, a better cam, 1.6 roller rockers, and roller lifters how do you think i'd be running? right now i think i'm mid 14's.

also if i did machine work to the heads when i took them off how much would that shave off my time? thanks alot.

 

that's an 89 gta with t-tops by the way, i need to get subframe connectors before i do all that stuff.

 

I'd guess high 13s. Maybe mids if you get good traction, which you should.

 

I'd say mid to high 13s with what you say you would put on. But like jd13 said traction is key in this.

 

are these times with the headwork or without? like port and polished, possibly 3 angle valves...

 

mid to high 13's with headwork. this should be on the drag racing board sister.

 

If you get a new cam, you don't need 1.6 rockers, unless you just like them. Generally 1.5s are less expensive. If you do everything right, and get it tuned I'd say 13s are in your future.

 

Agreed

 

actually it was theoritical, but whatever
