1989 Pontiac Firebird Transam GTA project.
350 Vortec TPI - Preparations Part I
It took me 12 months to gather most of the parts needed for my performance mods to the motor. Chevy L31 Vortec heads are being used, fitted with Comp Cams 986-16 1.43 inch diameter Comp Cams 986 dual valve springs, Comp retainers and locks, Comp teflon seals, pinned rocker studs. The heads are brand new, purchased from Eagle Spares at Revesby. They will be setup and machined by J.B. Performance at Granville.
