    i'm trying to talk myself into buying a new crank. i don't really need a 4340 crank for what i want to do, but i don't have access to any stock cranks either. looking around on the net i've seen a weight of 75lbs, ten more than a stock crank; is that an accurate weight? i've also seen that some eagles, stock stroke, don't require narrow rod bearings; anyone know if that's true?

    Call them and ask them all you want to: 662-796-7373.'

    I have sold a couple Eagle cranks, and they seem to be a good product.

      i looked on hugh's website and they state chamfered/narrow bearings are needed. mancini says they aren't needed,...? best bet is to call now that i have a phone number. thanks.

      I ran a hand me down 496 that ran a 4.125 and it used a hn743 brg. and the radius gives you the strength on the journal so yes a narrow would be needed on all manufactures of good stuff

      Be aware if running a 4-speed with those eagle cranks. Mine was not drilled fully for the pilot. It was drilled and appeared to be correct(which threw me a curve) but just not quite deep enough, found out after the motor was built and installed in the car. Ended up drilling the crank in the car because i had a hemi box and did not want to cut the shaft.

        I must of lucked out,I put a 18 spline behind my eagle 4.125 with no problems. My Pilot bearing did'nt go into the crank hole all the way either like Moparparts said,it in there all but 1/8"

        My Buddy Built a 360 Stroker and used an Eagle Cast Crank. It broke in 2 Pieces just inside block at # 1 Main Cap. It Now has a Molnar Crank. Tom Molnar used to work for Oliver Rods and Cranks. http://www.molnartechnologies.com/index.html

        i just got off the phone with eagle. all their cranks require a narrow/chamfered rod and main bearing. why some vendors are advertising otherwise has confused me. thanks for all your inputs.
