I cannot find the cam card for the solid roller so I will have to go with my best recollection. We made the switch on a 440 with EZ heads flowing 350cfm @ .600".
1st) Solid roller 270/270 @ .050 105 LSA and .620 lift plus 1.6 rockers (655 HP @ 6,500rpm)
2nd) XE285HL 241/247 @ .050 110 LSA .545/.545, plus 1.6 rockers, hydraulic flat tappet using solid tappets, and dropped to 595 HP @ 6,500 rpm.
You're starting with a much bigger flat tappet cam. So will you see anything like the 60 HP we found?
