Red Barchetta and JWD, McLeod sells to types of bellhousing. DEPENDING on the trans, You either get a one piece or a Modular Bellhousing. TKO500 TKO 600 and T-56 require the modular bellhousing on some Ford motors. The barrel for the flywheel is a formed 1 piece, but the trans plate is bolted to the barrel. I am sure that Red has done alot of testing, that it with stands and explodsion. IMO a 1 piece bellhousing is stronger than a multi piece one. I didn't check to see if the modular one is SFI certified. I am gald both of you have a one piece. I hope everyone is running a one piece.
I know on some motor trans combo's this is not possible at this time. But with enough want and need this will get either manufacturer to start maken them. I have acustom bellhousing from Advanced adapter that is for a V8 AMC with a 4 spd in a CJ-5 They cut 2" inches out of the bellhousing and rewelded it together. Lakewood It is not SFI certified. I have been told that the welding is stronger than the metal it is welded too. I am not into the 6,000rpm 4 wheel drive burnout and more. Broken too many transfercases,rears (both) and drive shafts in every direction. I blew up many clutches with only the disc being destroyed. No Flywheels, they where all SFI ones. I hope I cleared up my thoughts to you guys on this. IMO One piece is stronger than Multi. Rick Lake
