Pinning problem PLEASE HELP
Hello all. Long time reader first time poster. I have a 87 3gen which had a 305 TPI but I have now replaced with a 350 with the TPI engine on it. The only thing that is different is the injectors are out of a ls1 engine but they flow very similar rates. But I’m having a lot of pinning. Has anybody had this problem?????? A ls1 does run higher fuel psi.

I know in the TBI world, the module in the distributor is different between 305 and 350, and must be changed. Is that true with the TPI engines as well?
