Maybe on the big 265 Cu In Chrysler "Big" blocks, or even the 230 Dodge motor, but the 218 Plymouth motors can spin. I had a 48 Plymouth business coupe with a 218 that was balanced and blueprinted, with a milled fenton head at 10.0 to 1 with dual Weber 2 bbl carbs, and a custom reground cam that would spin to 6000 RPM. I did add external oil lines from the pump to the ends of the block "The Lee Petty" mod. to keep the mains oiled. Go to inliners.org There are a few flatties that turn some revs. Honestly the sound a flathead mopar 6 makes at 6000 RPM is very sweet. The biggest problem is piston speed at high rpm, as they are all long stroke motors
