I guess I should have posted this in here, so here goes...I want to install a Small Block 400 with a 350 Turbo into my '61 Suburban and I am wondering what is the best way to approach this. It had a 6 cylinder in it, with the motor mount brackets welded to the frame on each side. I would rather bolt on motor mount brackets but on a '61 there aren't any holes in the frame. Is it safe to drill holes in the frame to mount these brackets, should I weld them on, or is there a kit that can be purchased to mount a V8 into a '61. What other pitfalls should I be aware of before I proceed with this transplant...clearance issues, driveshaft???
