from what I remember of the Olds Toronado they were a front wheel drive car(and a BIG one at that) -I think that engine is a 455ci/in big block with a TH400 adapted to front wheel drive transaxle? you have your work cut out for you..hopefully the builder reworked the frame to handle the torque load imposed by that engine..what rear axle are you using in this? since the Wabbit(LOL) was a front wheel drive I'm guessing a Ford 9" axle or so was used?

read this,: Toronado engine and transm

the engine combo was also used in the GM big bubble RV's of the 80's..unbeliveably up front-under the cab
