Is this all the better i can hope out of the car? it looks like I might have to put nitrous on it to keep up witha TPI or LT1 car. I was hoping for some 14.5-14.9s. o well it ooks like I might have to sell the car. if my buddy with his new 5.0(stock from old man) puts any mods on his car im dead. time for some nitrous and maybe a LT1 CAR IS IN ORDER. thanks for the info.

If you want to keep up with a TPI car you should get some headers. If you want to keep up with any LT1's you'll have dig into the motor with heads & cam or drop in a 350 after headers.

See my signature. It's not too hard to get into the 14's with a 305 with stock heads, a lot of guys from the boards have done it with an LT1 cam, full exhaust and some other little things.

Around what times would it be with a 350 tbi only headers and open element

UnderCover89TBI

probably around the same. i mean your doing more mods to one engine.

Around the same as a 305 but doesnt the 350 have more power

UnderCover89TBI

yes it does. but as i stated. you have more starting power and then your doing only a couple mods. to wehre the 305 u were doing more mods to it...

Do you know of a good cam that i could use with stock lifters and would a 350 tbi keep up with a 350 tpi or no
