Who Is Running An R154 Behind A Small Block?

Possibly lined one up, and was wondering who has done these? What mods need to be made to the trans tunnel? Will this transmission handle 550hp and 600lb/ft of torque?

I appreciate whatever help and advice you guys can offer!

Wow...never would have thought to put a R154 in a Mopar...interesting. I own a '90 Supra with an r154 in it and I'm pushing an easy 420 to the wheels. The 154 is pretty bullet proof. My son also has a '89 with a 300+ rwhp motor running a w58...haven't had any problems with it, either. Interesting swap...good luck.

Yeah, it's an interesting option. The down side (in my case, at least) is the reworking of the trans tunnel/torsion bar crossmember. This is something I definitely don't want to do on this car, so A833 it is!
