Re: Tbi swap build thread
The original engine in your '89 IROC would be an L98, if it is a 5.7. That is gen 1 SBC, with TPI (Tuned Port Injection). Physically similar to doing a TBI swap, but you will have to pay more attention to the fuel system. TPI will want 43-46 PSI, compared to 13 or so fir TBI.
