Need a little advice with my 360 teardown

Rumble has got the right idea.
The 268 cam requires a lot of compression to not fall on it's face at low rpm, and you've got that covered with the closed-chamber Eddie heads. Here's the deal with those Eddie heads, combined with Rumble's Tight-Q plan; I have run 185psi with that combo and it burned 87E10 at 34* Power-timing,which is all the Eddies need. Some FABO members have reported 200psi, still on pump gas. So don't be afraid of pressure, with the tight-Quench design.
With a zero-deck 360, and those 63cc Eddies, a compression ratio of 10.7 is easy. It falls together that way,with just decking.
At 600ft elevation,
with the FTH 268* cam,and an Ica of 62*, your cylinder pressure is predicted to be ~ 179ps. That is a good number; the pressure will make a lot of low-rpm torque, and the 268 will bring it, at the top.
But;
Having followed Rumble's plan, I can almost guarantee that you will have more fun with the next smaller cam. And if you go with a solid-lifter design, then you can go one smaller again on the advertised.. And now you will have gobs and gobs of low-rpm power, so the 3.23s (typical rear gear) and factory stall (2500typical for a 340) can stay. And, the 262*solid-lifter cam with 3.23s will have the potential to make more mpgs than any stock 318 ever did.
Yes the Hi-rpm power will be less, but recall that with 3.23s, that 5000 in second is, what did I say? oh yeah 78 mph; and 60mph is just ~3850. In first, the tires will be smoking until you shift. So are you gonna miss 15 hp at 5000rpm/78mph? I didn't. I was having way too much fun with the right power at the right speed.
But at stall, to say 3800, you haven't lived until you have experienced an SBM with hi-pressure. On the street, and under 60 mph, I would venture to say that it can do anything a factory-stock 440Magnum of 1968 can do;pound for pound/gear for gear/and stall for stall. It almost makes me giddy just to think about it.
If you have not yet purchased a cam, check Wyrmrider's data-base.
