Are their anyone using the Molnar 4.125 small stroker crankshaft with the 2.00 rod journal? If so what length rods are you using? I’m looking to use a 6.300 but I can only find a 6.200 scat rods. Can some point be in the right direction? Thanks

Think compstar makes a 6.250 with that rod journal size
I ran a 6.300 compstar on a 4 inch stroker but not 2.000 size


69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight
418 BPE factory replacement headed stroker, 565 lift solid cam
Best so far, 10.40 @127 1/4
1.41 best 60 foot
6.60 at 103.90 1/8

What brand are you going to use do you have a part #? Looks like the 6.200 will be my choice

I think the box is still in the shop, I'll check shortly. The rods have are for 2.00" journal and .927" pins.
