Okay, I was planning on using my T-5 for the blown stroker motor for my 37 coupe. Problem is the T-5 is only good for about 300 HP and I know this motor will put out more than this. A local company showed up at a car show over the weekend called Modern Driveline (MDL) http://www.moderndriveline.com/ they make a super duty T-5 good to 450 HP and also TKO 5 and 6 speed units. They make an adapter plate for the Y Blocks and also a steel bellhousing. Instead of sending off my T-5 to "G-Force Transmission for a rebuild with their gears and main shaft, I thought I'd be better off  with a Super Duty T-5 from MDL and one of their adapter plates to use on my Cast bellhousing. However, MDL is recommending that I go with a steel bellhousing due to the "rotational Force" being put out with the kind of HP I will be making. I had not considered this issue before and aside from the high cost of the bell housing I'm afraid there will be differences in the dimensions between the cast and steel bellhousings that will cause issues with my rear tranny cross member and drive shaft length. So, do you think I need to go with a steel bellhousing for this set-up?
