[Gmecm] Fw: TPI on a 412sbc

[Rick McLeod]

In my opinion, you're going to be very dissapointed unless u use an aftermarket TPI intake/plenum/runners, as the factory becomes very restrictive above 4500RPM and about 400HP/Ft# limits. I know, I'm running 3 of them in different states, and have done quite a bit of research. Read Lingenfelters SBC book before your attempt this to know the limits and what you need to do to circumvent the limits before you sink $$ down this hole. TPI works great on 5L, which is what it was originally designed for, and was retrofitted to 5.7L but low RPM setups and prompted the GM venture into the LT/LS development to achieve higher RPM powers
