I think that will depend on the location and orientation of the oiling holes.  If that is favorable, then I don't know of a reason that it cannot be offset ground like any other crank.
It will not exactly be a 312 crank.  It will have 312 stroke with 292 mains.

Wow...I didn't know that . Will John M be able to offset grind the 312 SCAT cranks for stroker cranks?

The Scat crank will be forged so you don't have to consider cast crank issues.

Hi Charlie, I don't know what kind of heat treatment they do, however I know after heating the crank it is straighten and polished, the reason I do all work before heat treatment is the man balancing the rotating parts did not like to weld (add weight) or drill (remove weight) on a heat treated crank.
     

Cliff.  I'm surprised that ALL grinding and finishing work is done before the heat treating process with cast crankshafts.

In some production work I'm familiar with, my understanding is that the heat treating can be a wild card with parts 'growing' (!) or otherwise distorting during the process...  Perhaps this is not a problem with iron castings... like a crankshaft.

Cliff, would you know if the heat treating you have done is 'through' heat treating or 'surface only' heat treating?

Thanks for any clarification you can provide on this.  Appreciated!

Yes, I finish all work on the crank (grinding, balancing) before heat treatment, however there are a lot of people that claim that heat treatment of a cast crank does no good, Sonny Bryant was the one that recommend that it be done to my crankshaft.

Thanks Cliff for the info. So if I was to buy a new SCAT 312 crank this spring (as a back-up for my stroker crank if it fails) wouldn't  it need to be offset ground before being heat treated?

Hi, Bryant only makes new cranks now (did mine a while ago), however any crank grinding shop can get it heat treated, Scat should able to do this, the entire crank is treated, some say it makes it brittle, I do not find this to be the case, I am having a crank done in a few weeks and was quoted $100.00 by Castillo's Crankshafts Specialist Inc (714 523 0321) in La Mirada CA 

Cliff;
Can you give me any contact information on "Bryant". I'm thinking that when the new aftermarket 312 cranks become available this spring, I may just buy one and send it off to them for heat treatment. I can't pull my motor apart now, I need to get the car further along. About what did that cost? Do they heat treat the entire crank or just up to the first bearing?
Thanks,
Rono

Rono, I had Bryant do the crank that is in my Bird now, they heat treated it when I told him that it was going to be supercharged, it has a McCulloch / Paxton hybrid supercharger (VS57 front end, SN2000 back end), it puts 10 lbs in the manifold, I used a 312 cast crank, most guys say you can not heat treat a cast crank however mine is and has about 10,000 miles on it now, also one of the engines I am building for my supercomp car will use a cast crank (3.35 stroke), steel cranks are heavy and don't have center counter weights.
