I am starting to get close to the assembly stage of my 455 and want to put a 66 toro 425 pan and oil shields in/on it. I am putting the 455 (oldsmobile) in a 1978 Buick Regal. I will be enlarging the sump for more oil but not sure if I may have to modify the pan to fit the G-Body frame.

So does anyone know if the stock 425 toro oil pan will fit the G-Body frame? More specifically will the forward part of the sump touch the rear of the center crossmember under the motor, where the exhaust cross over usually goes?

 

And if anyone has some old low profile valve covers they don't want I could use some to practice on, I'm trying to make a set with clear tops so I can see my pretty rocker arms ;-)

 

I had to shim the motor mounts and crossmember a little bit. Pan would hit the centerlink, and rubbed every time you turned the steering wheel.

 

No kidding!!! I'm glad you said that cuz the front oil baffle is right there, can fix that...so does pan interfere with frame under motor??
