Good plan as it gives you room to grow. We already know the larger OF cam is a solid 550hp with 295cfm heads and 10 to 10.5 to 1 compression.
I'm hoping the smaller SP cam will have enough seat timing to support the ported heads, and why I estimated that it would fall between the 514hp we got with a 230/242/112 cam/unported heads and the 552hp we saw with 295cfm and the OF grind.
I also read someplace that the SP is offered in several versions, with XE and Magnum lobes. Not sure which one you are using but it will effect the results. I didn't see rocker arm ratio mentioned either?......Cliff
