I have been running hydraulic roller cams in the last few motors. I switched out to another set of JE's for a Compression ratio of 12.7:1 taking full advantage of the 110 octane And running a solid roller, 250/258, .595/.595 lift. computer program gives a idea of about 60-70 hp more then last year. an estimate is around 570 hp.Originally posted by Tinkerer
Solid roller? What were you running before?
What pistons and compression are you running?
