Missed on this combo?
Most pump gas engine are gonna fall I the 1.7-1.9 hp per cfm you dont see too many that hit the 2 hp per cfm unless there supporting 14:1 plus cr and 260@ 0.50 plus.
The cams and cr that seem to support the 1.7-1.9 seem to be in the 9:1-13:1 and 230-260.
I didn't read this whole thread but didn't see anyone say anything about the cr isn't 11.4:1 pretty low for that cam wouldn't another point or so in cr bring the numbers up 20-30 hp/lbs-ft?
And ain't that cam a little huge for 300 cfm ish head ?
