Been There, Done That
Oh My, Been Through All This.....
I'm running a Canton 7 quart "T" style oil pan. With MAC long tubes.
I had to modify the pan for the long tubes to fit, by cutting a corner off of the left wing of the pan.
To use the HPM drop solid motor mounts, you can't use offset rack bushings. Run standard dimension bushings, and use a bump steer kit like Granatelli, Baer, or MM.
The pan fits sweet, if you'd like to see pics, send me your E - Mail.
