4340 forged crank 3.800 stroke.
PRICE DROP! See Ebay link below.
This is a COLA crank. Forged in Louisville USA, Machined in Los Angeles USA. It is a 2 piece, 350 main, small journal. 6 inch rod, internally balanced. Small journal clears better at the cam and fits in the factory oilpan. Will fit right in a Dart SHP Block with standard cam height even higher lift cams with no machining. Small journal also lowers reciprocating weight. I bought this and had it magnafluxed, checked for straightness, mains polished out perfect standard. Rods 2.00 standard small journal (lighter rods, readily available). Fresh from the crank grinder. I planned on using this in a 350 main, SHP with 4.155 bore to build a 412 but ended up doing a different build. Will fit in a standard 350 block bored .030 over with similar clearancing to a 3.750 stroke but you end up with a 388 instead of a 383 and a 1.125 piston (readily available) zeros out a standard deck and a .040 standard gasket gets you perfect quench. I had a plan for this but they changed. This crank will easily take 1000+ HP and it is fresh from the crank grinder. It is ready to go. It is perfect. COLA is out of business but were one of the premier crank companies when they were in operation. A new USA made crank of this quality will cost you over $1500 new. Compare to Callies Dragonslayer or Lunati Pro series. This one is $1000. Would like it to go to a forum member.

Counterweights are knife edged, It was magnafluxed, Checked for straightness, Nitrided, mains are standard 350, rods are standard 2" Small journal. Set up for 6" rods. This is a sweet crank. If you are building a 500-1000 HP engine, High RPM, nitrous or blown this is a great deal.
