I have an '89 RS 305 TBI w/EGR... I'm replacing cam/heads/intake.. I'm upgrading manifold (edelbrock w/egr provisions)/ injectors/pressure reg./ ECM chip... HOWEVER, the EGR needs replacing. Do I NEED to use the original # EGR, or is there something else ??? Also, I have a NEW EGR left over from a truck overhaul... It is a '90 Chevy w/ a 350 TBI... WILL that one work on the 305 ?? Do all the mods make a difference on EGR ?? Thank you ..
*** Bless Chevy
