I think I'm going to slap my 440 into my duster
Go with the Schumacher motor mount for a small block to a big block, you will need oil pan #187 for steering link clearance. You will have to cut part of the driverside motor mount on the K-frame. This will before oil pump clearance. If you use a high volume oil pump, on some cars I had to use one of the shims that came with the motor mounts. The transmission will mount on the rear mount with no problems, unless it is a 727 that has a different tail housing. On some 727's you will have to notch the cross member on passenger side tunnel above the tranny for clearance. Your water pump to radiator clearance will a lot smaller, so you will have to measure which fan to use. I use Schumacher headers.
