I recently upgraded to a 383 and still running stock tbi setup on 1998 gmc c1500 Spider injection is leaking and can’t find parts. What can I do to get mild performance and if more out of it. 383 has eagle stoker setup with 5.5” rods mild cam lifters and rockers, vortex heads, flat pistons, x pipe exhaust and cat delete. Stock rear end. Please help!
