In keeping with my last thread I was wondering... just what is the max HP anyone has gotten out of a 3400sfi engine? I'm interested in both street legal and race HP.

not much has been done with one. i have seen 350 N/A HP on another forum i am on. this is with a 3500 top end and WOT-Tech stage 3 cam and a lot of tuning. and a single turbo 3.4L camaro with the 3500 top end made close to 600. not much has been done though with these.

also that 350 HP is with 11:1 compretion or 12:1 i can't remember and that is on a street driven car with 93.

i am currently throughing around the idea of building a N/A 3400 and putting it in my car

There are a few guys running 12s and 11s (I think) with these motors. I know of one guy slowly building a 3.4/3500 TT motor for his Firebird that is going to be a monster of a 6. Check out 60degreev6.com, the best place for info on the 60* motors.
