You got it!So, if I understand, it would also be beneficial with a higher CR (if I go there), just not advanced as much? At least Lunati's 2 degrees, maybe more?

That's okay, I should have a couple free hours after dinner...
I don't think it'll be "that bad". I recollect a LOT of us ran big hydraulic cams straight up in low compression motors when we were kids and didn't know any better. They sounded great in the high school parkin lot. They pulled good too startin about 4k. LOLiffin' you're gonna run that cam, i'd advance it as suggested. but as others have noted with that combo: low compression, blah stall, no gear and heavy car-- you've got a recipe for dog water. though, it'd probably run pretty good at highway speed.
there's nothing inherently wrong with that cam, but if you're looking to swap it i personally think that there's many other, more modern grinds out there that are much more suitable to the task at hand.

Good. So that means when I get my CR sorted, I'll be back to talk more about how much I should bump the cam forward. However it works, I'll shoot for at least 9:1, or more if that's how the parts work out. And acquire an adjustable timing chain set, as this one's not.You got it!
Hush up fool. lolit's survivorship bias.
also you old farts can't remember what you had for breakfast let alone fiddy years ago!
(i keed, i keed)
At 9:1......a MEASURED 9:1 and not "bench racin" 9:1, I'd go 4 degrees advanced. That would be 105 ICL.Good.

Those would be a No Brainer for me. Deep port the flanges of the performer intake to match a set of 1243 Fel-Pro gaskets (theyr'e a performance intake gasket for a 273/318, but they match a J head's intake ports well), and install the cam on a 105 ICL. The compression boost and low lift flow with 2.02 J heads would work pretty well. It would certainly work some better with the high gears and somewhat tight stall.I have a few other sets of heads, including a set of 2.02 J castings that measured 62+/- cc. So that would bump my CR, I just don't know if I need the bigger valves. Plan was to use them on another engine.
No guessing, everything gets measured and mathed.At 9:1......a MEASURED 9:1 and not "bench racin" 9:1, I'd go 4 degrees advanced. That would be 105 ICL.
