I would not run 50 year old valvesprings
For some reason Howards has not gotten back to several posters lately- let us know your experience
I suspect Howards is now grinding Hughes cams instead of Engle
Howard has one off the shelf cam
543 lift 271duration on the intake 224/234 @.050 112lca in at 108- compares favorably to the comp XE-HL grind
if you wanted it choppy squeeze the lca down to 108 as suggested above
Evidently Competition has Comp grind some of their cams - let's see what they come up with
I do agree that the MOPAR 484 is too big especially that your compression is not high
You did notice that it is about 10 degrees bigger than the others it's more like a 290 class cam
Duane Porter knows what he is doing
best advice

if keeping your lift in the half inch range Lunati 10230703LK (there is also the 60302)
it's a 268-276 .494 lift so you can compare the intake lobe to those comp 268 chevy grinds
