Engine build

im building a 446 engine with the man o war 351w block, afr 225 heads with 72cc chambers, .570/.575 cam, forged internals. my question is at first the engine is going to be all motor but im going to supercharg it in the near futer, m comprestion ratio comes in at like 8.25:1, is that to low to run on a natral motor for now or what its ether that or the 58cc comes in at like 10.7:1. thanks.

Some fords came from the factory at 8.0:1cr in the 70's gas crunch. You will be fine.

ok sweet thanks. ill have pics soon.

your fine...the only thing is is that your not making as much power all motor as you could but you have to run all motor for break in purposes first...it'll be just fine..
