I have a 494 Mr2 cv-1 headed Pontiac and we softened
the solid roller to 750 lift from 775...also eased the ramps
slightly but still carbed... it is very stout but at the same time
fairly smooth and easy to drive

Bob,
At this time, I don't have any plans to change the cam. This is a similar motor to yours, though it is an IA2 block 535. It ran pretty well on the street as it was but I wanted more reliability and the ability to see what was going on via computer. The carb was okay but sometimes hard to start and I really didn't like the smell of raw gas at idle. Both of these should go away with this setup as well as some hard cornering stumble issues I had with the carb. I've been advised that it will be a much smoother acceleration and to be careful at first because it will accelerate very quickly without the telltale 4 barrel opening sound. We'll see soon! I'm within 2-3 hours of firing it up now.
