Factory old iron just can't compete ... ??

426 HEMI and 427 SOHC...any others?
Yeah. Halfway through the 62 model year, the 406 Fords were cross bolted and ALL of the 63 406 Fords were cross bolted. There were a few versions of the 390 that were as well. I don't know about any other Mopar engines other than the 426 Hemi.
