We run the Howards 234/241 .545 lift hydraulic roller in our 505. It has run a best of 11.19 @ 121 mph at 3600 lbs. and 10.01 @ 133 on a small shot of nitrous at 3,700 lbs. All on pump gas at 10.3:1 CR and through the mufflers. Lots of miles and passes. Zero issues! The 3rd gear pull on the street is lots of fun!

X2 - the cam's intake/exhaust bias choice always needs input w/r/t the head flow data

That sounds small to me even for a stock stroke 440.

Two cams with similar .050" and intake/exhaust split, but one with 110 LSA and the other with 106, will behave quite differently. A single degree of lobe separation is as important as 4 degrees of duration. Please post the center angles, if known.
