the reason I asked is that - from the info I have -- the cam in the aluminum block test engine had a cam similar to the one I mentioned - more ex than intake - and a LOT of lobe seperation --

PS - operating range and backpressure to boost ratio is still king. If you can give me those two numbers, I can tell you within reason what the engine's going to want...

I looked at the duration numbers on Marty's deal and Marty had a 290 Intake/ 283 Exhaust (.050") with a 406 cid engine so Travis' comment holds a lot of water.
