... a 496" RB with approx. 12.5-1 comp. Indy 440-1 heads (mild porting and bowl blend) 1050 dominator running E-85. the current camshaft is an older Hughes grind:HEV5663BS with 1.6 rockers INT .626" EXH .642" duration @.050 int: 256 exh: 265 lobe sep: 108... I had been told by Hughes I could use a little more camshaft...


A little more cam? I'd say you're 15-20 degrees short of what that engine wants, depending upon the converter you mentioned.

The "If it was mine..." answer is, I'd try something around 272 at .050" intake, 276 exhaust & 110 LSA installed on 106 ICL. If you had a 5K+ converter, I'd go up around 4 degrees more on both lobes.

But since all my junk are stock-stroke 440s, it's just a s.w.a.g on my part.
