440 source has the .4.25, 4.375, and 4.50 as well.. Are you stating no one else has anything in stock other then 4.15 right now?
not as a seperate crank or a kit, as far as 440 source I am not too sure about their pistons, not a brand name as far as I know, thought they used to sell Ross, and I definately don't like their H beam rod's, have seen too many loose the bushing in the small end, looks way to thin and fragile to me and they just mash and desinegrate, I would conside their crank as long as nothing else is special to their product line, I do like the fact that their rod's are wider on the big end and the assembly has way less rod side clearance that a standard chevy rod on a mopar crank which seems to me would sling a LOT of oil and create a bigger windage problem,,,Thanks Andy I checked out Molnar and they have a crank listed.
