Guys, a 292 crank, stock or offset ground, won't work in a 312 block. Mains are to small...

Yes a 292 crank can be offset ground too 312 stroke, but will require aftermarket small journal rods and of course must be used in a 292 block. Not a bad deal though 292 bored .050 and offset ground crank in a later block and you have a better 312 than the one that Ford built.

Forgot to add the C1TE rods are 312 length so theres another option, but they may be even scacer.

Since the 312 cranks are getting so scarce, can't the 292 cranks be offset ground to 312?

312 cranks would be a good market for one of those aftermarket crank makers.

I appreciate everyones concerns and opinions as to what I should buy and how I should build my motor but all I am looking for are a couple of parts.  You can all rest assured that my motor is being built by a very competent Y Block machinist that you all now and love.

With thay being said........I am still looking for a crank.  Thanks !

It is a combination of all of the above, uneven deck heights, machining tolerances in the crankshaft, rods, pistons, block, etc. With all those variances, there is the potential that an assembly composed of randomly selected parts can be in or out of the hole farther than any of the others. This is where taking the time to measure, and machine where necessary really pays off. It's also why a blueprinted engine costs so much more.

Mike,

I'd really consider John's 312 rods at $325 only another $50. New, unfatigued and same length. Can't go wrong with a solid bottom end

Mike: Don't know, but this is the first time I've heard that a set of 312 Rods normally vary that much on dimensions? As for the deck height issue, from what I've seen in print on that problem, it usually occurs largely due to uneven deck heights. Yes, no?
