BGH, Grant has been saying for years it's the clutch and it's engagement as usually why trans break. Big power, spinning at say 7000 RPMs, sticky track and slicks, Trans is fine driving around the pits. Now get to the line, dump it at that 7000 with a good still clutch, SOMETHING as to happen? Either car moves forward/UP, clutch clips, engine bogs or trans breaks?

Over clutch it with power can break the trans. This is partially why slipper clutches and CLUTCH TAMER were invented. How many years were Doug Nash 4+1 and Richmond 5 sps running with power and slicks? And I think the Nash were only rated at 450 lbs/ft of torque. BUT there you guys running them got years.

This is why I said to Napa, he's got some $$$ to do it right, so just go T56 and you get it rated @ 1000 lbs/ft and be done with it. Get some to "message" the tunnel to look OEM if needed.

When I had my 1988 5.0 convert GT Mustang, I went thru 11 T5's. NEVER at the track, always just on the street, usually playing a bit. Car was stock at the time, with 100 shot nitrous, long tube headers and McCreary "DIRT 60" tire. Ran 11.70's.

"BANGIN" Bob Hanlon from Hanlon Motorsports used to have a front plate conversion for the later Mustang 5 sp, I think they are 3650s, that you could put it behind a chevy and was good to about 500/550Hp. They were plentiful and cheap, so you could by 2 or 3 and swap them out WHEN they had issues.
