Long Rod

[chevybanshee350]

I was just wondering what is the advantage of a long rod crank over a standard length rod crank.

new to this but what i've got out of it is that it put's less stress on the piston skirts because you have to run 795 series pistons which the is up higher in the piston.

It does put less stress on the skirts but not because you are using a 795 piston. You are using a 795 pistpn because you went to a longer rod and have to get the clearance back somehow. The less stress is because the longer rod changes the relationship between stroke, rod, and piston and puts less side loading on the piston when it rocks over at Top Dead Center. It is a good mod to do when you have to rebuild or replace your crank, but I would not spend the monet to do it before your crank is done.
