You are exactly correct sir, I didn't even think about that. The one I was referring to was a 95. 97 would
be Multi-port. I know Vortecs work very well with mild bigger cube motors, but with 4 v.r. flat tops, I agree with ericnova72, it would probably have too much compression. Being a 97, (OBDII), you should be able to do your own programming though.
