Rebuilt 302 casting heads available through Rockauto
I believe there was one pair left when I bought mine last night.
Thanks for the info, I'm currently rebuilding my 318 and haven't yet begun to put it back together. I have the bare block back from the machine shop, new pistons, crankshaft, etc. I've gotten some cam suggestions here on FABO, but do you still recommend finding my deck clearance before selecting a cam?
It is not a bad idea to check it, but honestly, for a mild rebuild like your 318, it is easy enough to compute it and it will be within a few thousandths + or -. You just add half the stroke to the standard rod length to the compression height of the piston and subtract all that from the standard deck height.
Strke/2 = 3.31"/2 = 1.655"
Rod length = 6.123"
CH for the 814's is 1.755" out of the FME catalog
1.655+6.123+1.755 = 9.533"
Standard LA deck height is 9.600" So:
9.600-9.533 = .067" down in the hole
The SCR and any DCR numbers I gave you over in your long thread are all based in this number, plus a number of other well-known dimensions. Yes, it can vary + or - a few thousandths but that amounts to + or - .05 in compression ratio....so it's not going to be ANY issue to run with that .067"-in-the-hole number for a basic engine like this 318.
FYI, you can feel a difference in your butt with a .25 change in CR; the engine will be noticeably different with .5 change, and it will be a different engine with a full point change in CR. So you can see why not to fret over .05 to.1 point differences; this is not a top fueler engine! LOL When you get to that 360 build, then it may be time to be a bit more precise.
