Thread: suggestions on 350 TBI performance

Tweet

Can anybody tell me what kinda trouble I would be getting into if I put a 125 horse shot of nitrous on my truck. I have a 1987 Stepside Chevy w/ a TBI 350, headers, and 2 1/2 in duals. I need to know if 125 will cook the heads, or if I'm just chasing my tail with spray.

Depends how sound the engine is now. Does it have a lot of miles on it? Is it stock? Any engine is only as strong as it's weakest link. I would use a wet system (seperate fuel system to feed the nitrous). Buy all the "Juice" safety stuff to protect against denotation.

Oh.... and make sure you have "BACK UP" transportation .... just in case. HE HE

my engine is full stock, w/ the exception of the headers, and a throttle body spacer plate from Helix. about to roll over 100K

before you put the nitrous in i would tear that engine down bore it .30 (just to clean the cyenders up) check the crank out get the heads done get a new cam for it also deck the block and heads just to make sure everything is even. and rebuild it. is it a two or for bolt main?

Thats what i would do.
