Figuring your c/r with the flat tops and 98cc chambers (if that's what they really are), and gasket of .039 with a standard deck of .025, your c/r says 9.14. I dont know if this engine is already built or not, but if you go with a steel shim head gasket, (.022) you bump up to just over 9.4 on your c/r. Im not sure that cam will work with that c/r, at least not effectively. Based on the adv. duration, it's pretty big for that c/r. I would check with the cam mfgr., tell them what you have, and see what they say. I would think 10/1 or better. Also, the converter at 2500? Im no expert on trannys, but something tells me it might be a little tight for that cam. I ran DD using 9/1 compression, and pretty much everything else as you gave it, and it shows 433 hp @ 5500, and 475 tq @ 4000. You still didnt say what you will be doing with this truck.
