I guess this question would be directed towards Blair , maybe Brent and Barry , who makes the 4.30 crank and whats the price range ? and any other info on this item .. Thanks Bud

RPM makes a 4.375".   You can get them for around $750-ish out of the box, but they will require a touch grind on the rods and mains before they will be usable.

Brent is correct.  Not sure you could see much diff between a 4.250 and 4.300 in most situations.  Crower, Moldex, and Scat can all create billet 4.300s for a price much more than a steel 4.250.  You get what you pay for in strength and quality.  The question is,  what is the requirement?  The high end cranks can be needed, or can be overkill, depending on the use.

I remember you using them in a build or 2 , and was just wandering where the piston pin was in relation to the ring land on the piston ?

Thanks Blair and Brent for the feedback.. Bud

I have a 4.375 forged crank I bought new from Barry R and had it balanced ready to go, found out I made a mistake and it was supposed to be a 4.250  I am going to sell it if interested, you would need to balance it for your rods and pistons.
