273 cam suggestions

Cuda, dynamic comp of 120psi is low for 8.5:1 static comp, was this with the 759 hydro cam? if your not running the 273 solid rocker gear the 759 cam
P4452759 .430"/.450" lift, 260/268 duration advertise? (not too big in my opinion unless that's @.050") 110 deg LS and apparently 2+ degree advance ground in, is not a bad option if you dial lots of advance start at+6 even +8, this will bring up your cylinder pressure to around 145psi,

if you skim your 302 heads too much the swirl idea is out the window, you could deck the block but sounds like your pistons are around 0.100" below deck, don't know if a 273 is happy with that much decking, upside you'll be lighter ;)

ideal would be if KB made 273 high comp pistons? then use 273 orig valve train, sit down with some master grind lists, and 'as one of the last parts to buy!' choose drivable lumpy that if set right should have no drama for 14's


and Rbob, "scallop rocker" is 'if you running 273 rockers with -.100" retainers to fit up to .500" lift cams with no spring bind without having to grind the base spring valve boss' is removing material on the rocker were the retainer will hit, bench grinder/ linisher, other trick is weld top oil hole and redrill were you scalloped in direction to the valve tip''''

you have a good high comp combo, noticed your lift is .501" so this will work but dont think the LT1/chevy brown springs will cut it, I went double springs after my head guru asked if I was racing, these chevy springs cant handle Chryslers fast cam ramp ability at high revs that .904" lifters can offer, apparently metallurgy/metal structure wear/soften out spring seat pressure quickly,
