Aftermarket Bellhousing and Crossmember

Been a spell... Anyhoo...

So I now have my Dad's 1970 CST/10. It's got a fairly hot SBC in it and a BW Super T-10 4 speed in it. The stock cast iron bellhousing, and also the stock bellhousing mounts from the frame.

Future plans are a hotter SBC and I'd like to eliminate the stock bellhousing and mounts for a lighter aftermarket bellhousing. I'd have to move to an aftermarket transmission crossmember as well. As it is now the T-10 is just hanging out there with no mount on it, and been that way since 1974.

I just hope I don't shoot myself in the foot here and then snap the ears off the transmission on a hard launch or shift with the transmission mount at the rear of the transmission. Maybe I'm just overthinking things.

Planning on a couple drag and drive events in the future. It's not gonna be a 9 second rocket, But realistically in the low 12's, and maybe breaking into the 11's. I'm reworking the T-10 to take it and just want to see what some opinions would be, or recommendations?

Thanks to you lot as always,

Gary

If you ever scatter a clutch you'd be glad to have a cast iron bellhousing over a lightweight one.

I have scattered a clutch... it's ugly. Will be using a scatter shield.

Use one of these and be done with it..
https://www.jegs.com/i/Lakewood/620/15003LKW/10002/-1

Depending on the E.T., MPH and/or sanctioning body, it may be a required piece of equipment.. Also use a steel or aluminum flywheel, not the stock cast iron unit.

Re: Aftermarket Bellhousing and Crossmember

Agreed, the last thing you need is a clutch explosion.

i can vividly remember a very hot big block I had a long time back that exploded the clutch pack on a hard launch.

It blew the can right off the back of the block, pulling all the mounting bolts straight out of the block. Luckily I had a rear engine plate that mounted directly to the chassis and this saved the engine from further damage. The trans input shaft was not so lucky.

I went to a dual plate system after that....NEVER scrimp on safety....

Re: Aftermarket Bellhousing and Crossmember

Back in high school I had a friend lose a clutch and a flywheel at the drags. Clutch went down to the ground and the flywheel went up. When the flywheel went up, it came about 1'' away from hitting his gas pedal foot and proceeded to peel the dash and windshield in half kinda at an angle towards the steering column. He was lucky. Never did put that Camaro back together
