Quote: I recommend our 251 cam: 251-260@ .050, .580-.560 lift with 1.6 rockers, on a 108lca. With an unported eddy head it should make around 460-470Hp with 10.2:1 compression, 750 holley DP, rpm intake with a 1" open spacer and TTI or similar header. With porting it can make 520+HP! Brian
You'll need more spring than what the eddy heads come with...around 140lbs. closed and 340lbs. at .560 lift.
