TCS has a nice Billet Aluminum direct drum. Holds a 34 element sprag. Comes with Billet piston. http://www.tcsproducts.com/products/...ect-high-drum/
First to second in the burnout box is considered a no no. Ultra bell housings only cover the rules in NHRA for bell housing. The case is suppose to have protection also. There's were the after market cases comes in with SFI ratings. The Cast direct drum is the one to worry about from what I've read. It can explode if it gets into the higher RPM's I guess. No neutral at higher rpm at end of track is what my instruction say with manual valve body.
