Want to build another motor


Asked by Aug 29, 2016 at 08:22 AM about the 1993 Chevrolet Corvette

Question type: Car Customization

There's a '93 vette for sale I'm thinking about. I've built a
406 before, but that's where my experience ended, a
motor with a flat tappet cam and carburator. Is the '93
Vette TBI? And a roller cam? I know I'll want to build a
motor for it. I was wondering what has to be done with the
computer if I plan to put in a bigger cam during the
rebuild? And would I have to change out the TBI or
injectors? Like I said, I didn't buy the car yet. Just
seriously looking into it. I would want to go with a more
thumpy cam, but not full-strip. I liked how my 406 rocked
with a Comp Cams split pattern 487/490 lift, 230/236
duration flat tappet cam.

Forget the C4- it is considered the worst Corvette for many reasons- if you want a platform for engine building the C3 will be the way to go- they came with carbs and they have come back in popularity- so you would have a stylish car with rising values-


I basically just want to know if anything would have to be changed with the computer, TBI or injectors if I went with a bigger (but still streetable) cam. And does this motor have a roller cam? (I would imagine it does)


This is the wrong forum search a real technical Corvette / Engine forum for step by step engine building and C4 engine management systems. This one Cargurus is more about changing fuses! or how to read an owners manual. Only a couple techs online here.
