sbc into 37 Ford trans

I've got a 29 Model A PK with 37 Ford trans and rear.I'm putting in a small block Chevy and have the right adapter.Please tell me as specifically as possible which Chev pressure plate I need.I think the disc will be easy-a 50 or so Ford,but not sure on the plate.Also,I guess I'll use the Ford throw-out bearing,which is flat and will require a 3 finger plate.Help if you can.Roger

Don't know how much this will apply to you, but

Several years ago I did a BB Chevy into a 52 Ford truck tranny using an Offenhauser adaptor (The original engine had been a 239 flat head). It sounds like you are in the same situation I was, I had the adaptor, but none of the small parts or instructions. What I ended up doing was using the stock ford clutch pressure plate, disc and throwout bearing. I had the Chevy flywheel redrilled for the ford pressure plate (it seems like it cost about $30 at the local machine shop). As the input shaft of the tranny was to short to fit into the Chevy pilot bearing, I had an extended one built from a piece of brass bar stock (basically it was the same as a standard thick pilot bearing. but extended out of the crankshaft about 1/2"). As I found out researching my setup, this was exactly what offenhauser originally supplied with the adaptor. I used the truck on a regular basis for about 5 years and never had a problem with the setup. Hope this helps.

No reason to have the chevy flywheel redrilled. In the 60's I was running a sbc in a 36 coupe. Used the Offy adapter and a Schieffer 10 lb alum flywheel. I can't remember if it was 10 or 10 !/2 in, but used a Chevy pressure plate and a 48 Ford clutch disc and Ford throw out bearing.
