440 Build Suggestions

The stock stamped rockers have been very reliable for me with the old Comp 292 magnum . 244 at .050 duration, .501 lift. Tons of street miles and some drag racing with one rocker failure and that was 20 years ago. No problem since. Stock pushrods too. I don't think I would try them with one of those fast rate High Lift cams though. Speaking of the HL series, I've heard that a couple of engine builders have had valvetrain instability issues with those. 3.23 gears are just fine. Went 12.35 at 107 in a 68 Sat with 8.5 440 ,906s, old Torker, 750 dp, Comp 292, 3500ish 10 inch GER converter and 28x9 ET drags. Super low buck combo. A nice 10.5 440 like yours with TFs should be easily in the 11s with 3.23s. Don't be afraid to put some converter in it.
