Just to be clear...I chose the cam! It was my choice, and I wanted to use a cam that I believe would make great power everywhere in the operating range I wanted (2500-6500rpm), and also keep cranking psi in check. A custom cam would have made better power in certain spots, but difficult to make more power everywhere from bottom to top.
If you stray away from the combo we layed out, be careful...as mentioned with an iron head compression is pushed with 10.4:1...that's why we put that cam in almost straight up!
Also, cams are being talked about very cavalier....not good! You cannot just get close with cam timing, and have the same results. Not even close!!
If you plan on changing cams, you will most likely either need to drop compression, or play with the installed specs of the cam. This can change the characteristics of that cam very noticeably.
Edelbrock heads OOTB, will be down on power over the iron heads we used by about 20HP.

Brian,
Looks like in recommending that smaller cam i overlooked the fact that it would probably require a different piston to get compression down to a liveable level. My bad. If i figured it right, to get cranking compression down to about what the mid sized thumpr cam produces, the smaller thumpr cam would need to have the compression dropped to about 9.9? Would the smaller cam be a good a fit for 6000 shifts? I assumed it would since it is four degrees smaller with the same lsa. All this would be assuming an installed centerline of 107 like the other cam.
