Crankshaft - What is it...? - SOLVED:Kellogg - 11/08/22 06:04 PM

Rifling through some old boxes in the basement and came across a crankshaft I am not sure what it actually is. In a Direct Connection crankshaft box with no part numbers on the box. Found some numbers on the 1st counterweight.

It's an 8 bolt flange crank with a pilot bushing installed. Doesn't appear to have ever been drilled for balancing, probably new still.

With that wide collar on the front it's a big block crank is about all I can tell you.

Did some more research and found crankshafts in an old Direct Connection Catalog. One crankshaft available at that time carries the last 3 digits 285 in the catalog. Maybe that's what it is...

Post a better pic of a main and rod journal showing if it has a full radius journal or undercut.

If full then AAR4Fun nailed it.

Both are Full Radius. Guess it's an old Kellogg crank.

If I recall the only difference between the SS and ProStock cranks were runout, more select (less RO) for Pro.

They were great cranks.
