Hey all, kinda new to the forum. Referred to the forum for years for my truck then finally decided to make an account!
After some searching through the threads, I haven’t seen much on either the $2800 ATK High Performance 350TBI or $4000 ATK High Performance 383TBI engines for 1988-95 trucks. The numbers seem good, as do the prices for a new crate engine. I was thinking about getting one of the two to swap in to my 1993 C1500 along with EBL Flash II software to run it. Probably the 350, with a ported TBI and eventually add some low boost via a centrifugal supercharger. Goal is to have a truck with 300-350rwhp. Not really interested in an LS swap anymore, the prices here are sky high($1200+) now for engines with 150k+ miles (4.8 and 5.3’s, 6.0’s are even more) and being OBD1 I am not really interested in building wiring harnesses and using stand alone management. My truck currently has the stock 2 bolt main 350tbi with 160k miles on it, with headers, custom exhaust and a single stud air filter.
I see some people saying stay away from ATK and others who have had good luck with them. Wanted to see if anyone had used one of these, and if they actually make the power they say.
