Benefit of Chevy........

what is the reason some guys use the chevy profile on their crank journels?? more rod availability?
~thanks

the same reason anyone buys a chevy or builds a chevy

parts availability and price!

The reason a Chevy size rod journal is used on big block strokers is that it frees up a little room. And rods and bearings may be a little cheaper.

The chebby rod journal dia is much smaller than the b/rb so the Mopar journal can be offset ground for more stroke IE from 3.375" to 3.900" using a chebby rod bearing on the big end of a rod w chebby dimentions. EDIT I meant 3.750" for the (RB) stroke

Thanks! and sorry for the newb question.....

Also, smaller parts are lighter parts. A good thing when dealing with parts that change directions VERY rapidly.
Travis..

Chevy pins are also smaller & lighter

yup, stroker guys use them for clearance, and the performance of them is that they are lighter.

that's why 440source offers a 440 length rod built with chevy ends--smaller journals for more crank throw clearance, and smaller pins for lighter rotating mass.
