I gues it could have also, siamese mega block hemi. I will look through th paper work again but didn't see where it was purchased from. did they sell a blower crank back them? and i wonder who made it? i don't think chinese cranks were available back then?

I guy I know had a crank like that in a B1 motor. We looked it over and thought it might be from Crower or COLA(no longer in business). But still not sure. I can't blow up the picture you posted so I cant tell, but the one this guy had had nicely finished counterweights and looked very high quality.

That looks like a billet crank... notice no forging
lines on it... I looked in my 2000 parts book and didnt
see any listing for a double key way crank

Chrysler sold these cranks under P/N P5249208 and superceeding P/Ns,they were supplied from various crank manufactures.They were forged and could be bought unfinished,both in raw forging or unbalance.P/N P5249164 was raw forged to be machine from 3.75 to 4.15 or smaller for oval track use.P5249503 was machined but unbalanced for aluminium or steel rod applications.Chrysler also produced the the Kellogg crank P/N P360285 and P4529095 fully radiused.

Crower and all the biggies mark them somewhere. You nedd to really if it was done with the little hand held engravers. They hardly leave more than a scratch.

thanks Fred, I am really not concerned. I am pretty confident it's a billet Crower.

Top of the line build forgot to include flat washers under those top of the line main bolts.

are they really needed? is there any reason to have concern?

ARP includes them for a reason. I would think leaving out the hardened and ground washers would throw off your torque value a little. What advantage is there to leaving them out?

Not to mention who uses Oliver rods and billet cranks and doesn't use main studs?

I was gonna go there, but I didn't want to sound too critical.

The purpose of the washer on arp's is to give the radius on the bottom of the bolt head room to sit flat. If not the bolt would gouge into a drilled hole that wasn't radiused.

Either way a hardened washer is good insuarance.

Re: Help ID this hemi cranks - 12/06/10 02:27 AM

good to know, this is the way I bought it, and can't complain a bit

easy fix

it has studs on the top end. guess the builder didn't think it was needed

don't put studs in it now, just put washers under the bolts, and use the correct torque for the lube you use. one at a time.
