360 build questions.

Tnx for the reply and interest; it's no problemo computing the bobweights here with the rod/piston parts. What I would like to know is:

If one had a standard cast 360 crank from an LA (not magnum), like 3418640 (which I just pulled out of my a..... err, off the internet....LOL), and you could attach bobweights that would balance with the stock, unmodified crank without the external damper and flywheel/flexplate weights, what would that bobweight be?

With that number, then one could work backwards with the usual piston and rod weights to see if there was a combo of lighter pistons, rods & parts, etc., that would compute up to that bobweight so that no added Mallory would be needed for an internal balance.

With forged pistons and such, I don't expect there will be any way. With hypers maybe, but it might also require some very lightweight rods which may be impractical. But there is some rod weight that can be taken off of the pads and the casting seams on the beams. And, the reciprocating weight associated with the rods can be reduced by boring into the crank centered at the rod journals in parallel with the crank axis; from what limited amount that I know, this is not uncommon.

(Plus I guess am assuming that the 360 counterweights are set in the same orientation to the rod journals as in an internally balanced engine and can be used uncut for an internal balance procedure.)

If this has all been discussed/worked over before, forgive my asking; I'd appreciate being pointed to the info.

And my pocketbook might allow the high temp oil (never heard of that one!), but this is for a lower buck project.
