Your suggestions please, I am jonesing to build.

Ed - From the sound of this you have been looking for a reason to build another engine. I would have started with backing off the timing to 34 and seeing if that allowed you to run pump gas. Most everything I've seen says mopar smallblocks like 34-36 total, and you're running 38 total with a high compression ratio. Your cranking psi is really high, and a cam with more duration would bleed off some of that pressure. Increasing your volume at tdc would do the same thing (i.e. thicker head gasket, bigger combustion chamber, dished pistons, etc). If $ is truly a concern you could at least try changing the timing first, then pull your heads and start measuring volume and stroke, it won't cost you anything. Good luck on your build.
