Anyone done it? I will be in the next few years after I finish building the motor. Any help would be greatly appreciated!!
A friend of mine ran a 392 in his '66 Charger until he could afford to get a 426 done up for it. Car was a real 426 Hemi car that he bought without a powertrain. I don't know what he did for engine mounts, since his had Hemi crossmember. I think if you use small block mounts, the old hemi will drop right in on a V-8 crossmember. The engine will bolt to a small-block 727 transmission. You have to buy a spacer plate, because the drive plate mounting surface is farther out of the block on an old hemi than it is on newer motors. 8-bolt new Hemi drive plate bolts up
His crossmember was different than yours, unless you too have a Hemi crossmember. I am pretty sure the old hemi engines had the engine mount ears positioned on the block identical to the old 318 Poly blocks. When the new 318 was engineered as a thin wall block these ears remained the same, since the old 318 and the new one were interchangeable in cars. In 1967, U.S. cars got the new thin wall 318, but here in Canada we still had the Poly.Yes, I have the Trans-Adapter and SB 727. Do you still have contact with him to confirm the K-frame and mounts?
Thank you!

The 392 weighs a ton! better off with a big block it will be cheaper, lighter and make more horsepower.
The 392 weighs a ton, 740lbs! Better off with a big block 440 (670lbs) or 400 (620lbs) it will be cheaper, make more horsepower and parts are available.
