Quote: The k-frames are physically the same pieces, the difference is where the motor mount perches are welded onto the k-frame. My car came with the 440 in the small block k-frame with original type 440 mounts. It fit in but I have since changed to the schumacher conversion mounts. When I first got the car, the 440 sat too high in the front and too far forward. The conversion mount dropped the motor down about 1" and moved it back about 1". I now have more fan-rad clearance and it got rid of a pinion angle mis-match which was causing a vibration at speed. It fit with the mis-matched stock stuff but I now have more clearance for aftermarket intakes/air cleaner and my el-cheapo summit headers fit great.
....And the whole trouble and confusion begins with the fact that the big block WILL just sit right in there tricking someone into thinking it's a done deal...They should have spread the mounts from BB to SB to avoid the confusion...
