Cylinder head decision for 318

If you map it out, the smallest whiplash cam is like a 2bbl 360 cam with the LSA closed up to increase the overlap from 32* to 48* to punch up the idle sound. This also raises the operating rpm a few hundred, just what the 318 needs. The compression duration is about the same, and the power duration is only perhaps 4* less.
I have had two Hughes cams, and on both of them the difference from .050 to advertised was ~47*. If that holds true for the small whiplash, then it will come in around
260/272/109+5,with 126*compression/110*power/48*overlap
And the 2bbl 360 cam is
252/260/112+4, with126*compression/114*power/32* overlap
So no problem, as they say, to run up to 8.6Scr.
The problem is getting the 318 up to 8.6............
If you don't at least try, then the bottom will get soft, and you will need a higher stall to get past the softness.
I have run the 360-2bbl cam in an otherwise stock short-block low-compression 318, with just headers and a 4bbl; with a 2800stall, and I liked it, even with just 3.55s. Jus saying.
IMO the 2800 was a game-changer for that combo.
