Here's what I see;
The cam is a high rpm cam.
The heads are dead at 4500
The stock rebuilt bottom end is sub 8/1 Scr, the 318 heads might bring it back to 8/1. But it doesn't matter, because the XE 275H, will kill the bottom end anyway.
So what you end up with is an engine with a powerband from 3500 to 4500. But it's a cruiser so that might be Ok.
But something will have to be done with the marshmallow bottom end, and this
is a good start, but yur not gonna get away with 2.76 rear gears. Consider 3.23s as the absolute minimum
Yur not gonna like this combo much, cuz it's gonna feel as tired as your 318, until the engine gets up on the cam.
With 3.23s that will be about 34 mph.
Having said all that, the cure is a smaller fast rate-of-lift cam, with an earlier ICA. Leave the rest alone, and you will have a nice cruiser. Lessee,on an LA, Ima thinking a stock 360 2bbl cam if you already have it, Or up to a 262 if you have to buy one.
But I just gotta mention that a 318 2bbl cam would kick azz with that combo, in a cruiser.
Why am I so confident? Because I did that to a 340, back in 75 and that combo is my second most favorite cruiser combo ever! In a 360, it has just got to be even better.
