Carrillo Crank Kits
BB Chrysler (lighter assemblies)
Performance High Quality Kits at an Affordable Price.

I don't know anything about "flatlander racing"
anybody dealt with this company?

Sound like good parts, but what do I know.

Looks like they only come with short rods. Depending on the stroke, you're going to end up with some pretty low rod ratios?

whe sell essentially the same kit, but with longer rods and diamond pistons. we don't make little footnotes about adding rings or bearings or upgrading bolts. we simply make the better parts, part of the kit.

Flatlander is basiclly a mail order storefront , most everything is dropshipped from a warehouse. I live a couple towns over from him , runs it out of his small home. When I went to pick up a scat crank I bought from him years ago he was building an engine in a shed with what looked like a dirt floor ...

I'm sure there are a few heads here that can steer you right.
My experience and choice is anything machined, balanced and blueprinted by the BEST MACHINE cats in Detroit is first class act.
They know their math and science behind all this history.
