How do I calculate compression or guess
Well, you could "ball-park it", to help with piston selection. Then when the pistons are finally in the block, you can work out the rest.
Or you could mock it up with what you got,get an in-the-hole measurement for that piston, then pull it out and measure the compression distance. A little math can then get you close to the actual block deck height.Close to, but not exact.
But I just gotta ask; What are you up to?
Code enforcement is cracking down again. I surprised him cause my two rolling chassis are registered, licensed, insured & now he wants 'running' -ok.
But every time I get to a running 360 it sells before I can buy it.
I have rebuilt j heads
& a deal for another set of assembled J heads -.040" milled.
Was going to put together two lowish buck 360's for 2 rolling chassis to finish out my hobby.
I Have: water pumps, timing chains, intakes, 273 rockers, a few block-cores, I think Rusty still has my distributors & I got to get him 2kits for the weights, 1 new eddy carb, rocker shafts (I need to know about them & 273 rockers), 2X headers, overhaul gasket sets, bolts, alternators, cam shafts-springs-lifters-retainers, valve covers, -some but not everything to complete & the budget just got better this 1 June to try & finish this up.
I have never done this before though. I have the books, & still need a few parts.
I am getting ready for deployment & would like to get this knocked out before I go to end the drama.
