pontiac engine install

[mud_grip]

hello all. i realize that this may not be a real popular idea, but i am planning on putting a 400 pontiac in my 1969 chevy. i currently have a sbc 350 with granny low 4-speed in right now. i am having tranny problems (a story for another thread), so i am replacing it with another identical tranny. i really like the torque pontiacs have, and my friend is going to basically give me one, so i am thinking of replacing the engine as well (too sweet of a deal to pass up!)

so here is my question: has anyone ever installed one of these in their trucks? unless i am missing something, everything seems to check out, except for the engine mounts. i have a 4-speed granny low tranny that i will be using, so the manual tranny pontiac belhousing should work, and i will be using my HEI setup, so i will change distributors as well. anyways, does anyone have any suggestion for the motor mounts?
