looking for steel 3.85 crank

Post  72mach1 on September 11th 2013, 9:55 pm

i screwed up my block that had 351c journals, so I need a steel crank to put back in my new a460 block. Does anyone make a steel crank with a standard stroke, all I can find are 4.14, 4.3, 4.5, I don't really want to get rid of my rods and pistons and change the whole combo.

Someone said that king bearing makes a spacer bearing but I talked to them and they have never heard of such a thing neither has clevitte. If someone could provide a part number that would help.

That's a custom part..... You can make one out of a 429 steel crank if you do Chevy journals.

Pro-Gram Engineering makes the bearing spacers to convert 460 mains to Cleveland mains. They are expensive for 5 of them (uppers), and very expensive for 10 of them (uppers and lowers) assuming you don't just buy the uppers only and then use them with main caps that have Cleveland mains.

Forged steel 429 truck cranks can be converted to 3.85" stroke cranksafts. This requires the 429 steel cranksaft core, the offset stroking, the snout re-work, the flange rework, etc. By the time you are done modifying the 429 steel truck crankshaft you could have bought an offshore stroker forging and put the extra remaining cash back in your pocket. But if you need a forged crankshaft with less than 4.14" stroke then this is one way to do it, and probably the most economical way at that.

Adney Brown can fix you up w/what you need. The last one we got from him was close to a grand finished.

Ford Racing and Federal Mogul recedtly used to offer main bearing spacers to go from 351W to 351C main journals.

They work well in a Big Block if you can find a set.

My rods are already the 2.2 journal so offset grinding a 429 truck crank I could do but it took me several months to find a usable truck crank for my 450ci motor and had a little over a grand in it when I was done.

How expensive are the bearing spacers. I can see them being high dollar since it would take a full ring for only 1 bearing half

The way it's looking I may be selling my brooks rods and .080 venolia pistons and starting over with a stroker

Post  514Fox87 on September 12th 2013, 9:30 pm

I have a 429 truck steel crank that has been offset ground to a 2.375 journal, 3.71 stroke. Still has room to go to 3.85 stroke with 2.200 rod. PM me if interested.
