First off, the pieces that make up this set are VERY well engineered and manufactured. They are a little pricey at $250/set + shipping.
I bought a used set from ebay for half price and was excited to have the ability to move my 351W around to fit in my '65 engine bay. After a couple of attempts to seat the motor properly and not having the success I thought I should have, I looked on the RMP website and lo and behold there are TWO different frame plates that can be used with the adjustable motor mount. I had unknowingly gotten the frame plates that lower the engine 1/2" from stock height. That would be ok if I was installing a 289/302-based stroker but used with the 351W and you are going to have the hedders clashing with the shock towers (at least on the '65-66 model). I called and actually spoke with Ron Morris and he said with my engine/chassis combo that I should use the normal height frame plates and it should fit. He even explained which holes the frame plates should be mounted in.
