I'm back into vettes after about a 10 yr drought, and of course am already (only had the car for a week!) thinkin' about another engine. I'm OK on the pre-smog stuff, but need some advice about what works with the 85 ECM and OBD. Logic tells me that one of the World 427 internally balanced small blocks with stock cam, 750cfm maf, 30lb injectors, 58mm throttle body, large tube injector runners, a little less restrictive exhaust with a larger Catalytic converter and a little more fuel pressure ought to sound and work with the ECM about like stock, just with a bit more "OOMPH". Any of you youngsters out there know enough to tell me if that's so, or where I can get an engine that's not too radical, but still with a little more power than stock? Most of my driving is interstate crusing at about 75mph, so driveability is important. Thanks in advance for your help!
