FWIW I have a 360 crank also with drilled counterweight holes, just like yours,and some rounded corners, although some are beveled. the rod and main journals have grooves on each side. the number is 4027169-3 followed with a circle with 6 pie wedges in it, and the the letters CFDafter that. the number is cast in, by the way, and there are other castingmarks and ridges also visible. I read that all 360 cranks are cast ,,,but I also have heard that if you tap on the crank with a tool or stick/whatever and it rings like a bell, which mine does, then it's a forged steel crank? so I'm not sure about that test? I also noticed some grooves cut in concentic circles on the side of some of the throws? My crank also has grease pencilmarkings on it, but I wont confuse the matter any more with those.I was and still might use this crank for my Poly stroker project some day,when I can afford the machine work.

It looks really nice inside. But I will have to messure all the parts before I will make any decisions. Anyway the crankshaft has number 3418640-2 and in one of my books it is said to be a cast shaft. In another book it is said that the 360 were made with a forged crank that are internally balanced. The difference is the counterweights. Forged is rounded and cast is sharpcornered. It looks like mine are round cornered. And the counterweights are drilled with holes somelarge at the end of the crank. And smaller ones at the other weights. Please help me someone?

[mailto:spigot2039@xxxxxxxxxxx] Sendt: 20. marts 2009 13:30 Til: 1962to1965mopars@xxxxxxxxxx Emne: aluminum - steel flywheels (was Re: Fw: Flywheel) I believe the aluminum flywheels are favored by the circle / dirt trackracers as for fast rpm increase heading out of the corners. Mopar engines put out good torque by design so don't mind the steel flywheel on street ordrag use. Thanks, Gary H. -----Original Message-----This brings up a question I have had and may help Knud in his decision. Iknow aluminum flywheels being lighter , will overcome inertia quickertherefor gaining RPM faster. In a big block B body with about 3:50 rearend ratio - 4 speed-5500-6000 RPM limit - about 375-400 Horse -any advantages or disadvantages to running an aluminum flywheel. Drivenstreetand every so often on the strip? My thoughts: a 413 has enough torque to get you off the start line ( or from a stop sign) without the inertia ofa steel flywheel. The aluminum flywheel would wind up quicker, Any experience out there with the aluminum flywheels?...................MO.......ew iowa---- --- ----Please address private mail -- mail of interest to only one person -- directly to that person.
