350 to 383 stroker with tbi setup

PopTailGate1998 · Jul 13, 2024

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!

I'm a TBI guy, but I believe most ditch the spider system for MPFI, believe the go to replacement is made by Delphi.

Google MPFI Vortec conversion, and most likely you will be sent back here.
Or use the search function on here.

Did some digging and found the clip at local parts store. Looks like the same as the one in the videos on rock auto
