That's why I asked about a raised cam block, BES does stuff like that also. APD does alot of testing on all kind of stuff, they had a real good article a couple of years ago on some Big Chief testing that they did. I don't think APD gets as much credit as they should.
Actually do not need a raised cam block. Mine is a 4.5 stroke in a 9.8 deck also.

That article was the start of a major change in cam profiles, the engine was a good friend of mine, he purchased from a big name builder and put a terminator on it. It developed the mystery "alky miss" and did not run nearly as well as it should of. APD was close so John Kyle did a bunch of work and figured it out with a cam he designed. They also have designed some of the best bbc heads on the market.
like to hear more about this 'alky miss'....is this the miss big inch alky engines develop...and a longer exhaust duration helps clean it up?? :?:
