Yep, I'm a member of FAST,.....great guys!!!

Ford "C" engines as many refer to them are just glorified "B" engines,...the one thing that they often have are counterweighted cranks,....they make for great cranks in both "B" engines and "A" engines however, you have to turn down the crank journals on the crank if placing it in an A block,..no big deal, doesnt harm anything. Getting an engine built right now and turning down a "C" crank to put it into an A block. Also, many guys tend to stay away from B engines and Cs due to the fact that the deck is much thinner on them than your run of the mill Model A blocks. What results oftentimes is a cracked valve seat area,...I have one B block with a cracked valve seat area,...not good.

Many guys in the 30s and 40s DID run A blocks and did VERY well with them,....Bs were favored more so because they were almost a full pressuredized oil system right from the factory,....BUT were not fully pressurized,...this is a misnomer!!!

I'd see if that engine you have has a counterweighted "C" crank, take it out, get it magnafluxed at a reputable shop, if its checks out good,....take the cam and flywheel from the 'C" engine out,...and sell it off,...keeping the cam, flywheel and crank.

THEN, get yourself a good solid A block/engine, take it to a GOOD reputable engine builder who knows Model A engines (NOT some goon who has a client base made up of muscle car customers,....you need someone with true knowledge and experience not a guy who's unfamiliar with early iron!!! ) Then get your engine built from then on it,..using the C crank, B flywheel, and (if the cam checks out to be good and the oil pump gearing is usable and not shot) then you might use the cam also,...might even want to get it reground,.....OR you can order a whole NEW cam from a guy like Bill Stipe. Though if getting a cam reground, go to Jim Brierly, or Bill Stipe,...they really know their stuff!!!!

Hope this has helped some!!?? I get my info from experience, and talking to thos who have actually DONE it, built the engines and run them HARD!!!!
