69' Steel 302 Crank - Infor anybody?

Shawn · 08-09-2000, 09:07 PM

I'm asking for any information pertaining to a 1969 Steel crank I am possibly going to purchase. It has the $ sign and B designating steel, it has been freshly cut 20under...does anyone know how much a crank like this costs, what type of steel it is made of, I have heard it is forged from several people-is this true, also has anyone used a crank similar to this and what RPM range it is good until...thankyou for your help!!!!

The term steel crank indicates a forged crank but I would be really careful since someone selling this crank could incorrect. The only 1969 302 crank that I know of that was forged was the Boss 302 crank. The forged crank and the cast crank are supposed to have distinctive sound differences if struck with a hammer or wrench or something.
If it is a cast crank I would guess around $50-$100. If it is a boss 302, good question. If it is as aftermarket forged crank, $100-$200 (just a guess here).
The cast 302 crank is supposed to be pretty good for high rpm use. I would guess 6500. the forged crank in the boss was good to around 7500 I think. I don't know how smaller jounals will effect upper rpm range, but it should wind up faster, less angular momentum.
Some of our more experienced engine builders can probably give you better info.

last post was right boss 302 had steel crank, ford did not use much steel cranks and four bolt mains as the others they saw no reason and had no problems. if in fact it is a steel crank can be worth quite a bit min. $500 the 302 im buiding will turn 8,500 just fine. eagle rods sonny bryant crank ross pistons and lots of block work.....
