Topic: Boss 429 Crank?

[76cobra]

Hello, I'm new here and found my way here looking for some info on this crank I acquired in a package deal (Dove CJ block,Boss Crank,Aries Boss 429 blower pistons 8-1 and a few small items). The block is what I needed for my 76 cobra stroker motor.Anyways this crank has # C9AZ 6303 E, V48 is also forged in one of the counter weights, on the snout end counter weight where its obviously been balanced it says 9HM266 and some other # I do not know where to find info on this crank, another fourm I use wasen't very helpful, I'll try to post pictures if I can figure out how. Thanks

I looked for about an hour for information about the 9HN266 number, but to no avail.  The C9AZ is for a 1969 Mustang engine.  Ford started production of the Boss 429 in January of 1969, so it is possible that it is a boss 429 crank.  You will need that number broken down first.  Sorry I couldn't help.

I am not sure if it's from a 429 or not but it's coming from a Galaxie.
Here is the info I got:

C9AZ 6303 E


C = 1960
9 = 196(9)
A = Galaxie
Z = Ford service parts
6303 = Crank
E = 390c.i. ?
