Edelbrock makes a carburetor set-up for both versions of the 4.3 but it gets ify right about the 95(these rigs are built fot MARINE,chevy puts a jillion of these motors in BOATS) model they speak of the vin code w then they talk of a letter T on the face of some engine blocks (drivers side right at timing chain cover) another bunch in Cali acted like they would produce a wiring harness that would allow to leave the 95 4.3 vortec (with its factory intake)and mate the harness to the gmcs,they quoted a $225 (that I would gratefully pay!) then said they were not set up for the vortec YET, boys and girls I'm lost.
