can i run 6 or 5.7" rods with stock crank?? i see theres 2 pistons with difernt pin hights. im geting eagle h-beams and kb forged pistons. also what do i need to get balanced? hope i dont sound to dumb thanks.

 

you can run a 6" rod with the stock crank. As for balancing, you need the rank rods and pistons....Talk to the machine shop and see if they want the bearings as well, some shops may.....

 

So i can run a 6" or a 5.7 just have to have the right pin height piston? is there any advantage disadvantage? I think in the unforeseen future I may or may not build a 383 so that would be a reason to run a 6” rod right? Thanks for your help guys

 

Yep, in fact I will be running a 6.125" rod in my new motor.

 

and still only 350 ci? wow what the anvantage to a longer rod? shorter piston? lighter?

 

Longer rods increase TDC dwell time, which IIRC makes the engine a little more detonation-resistant. It also improves rod/crank/piston geometry, which can reduce the wear rate on the cylinder walls. Handles high RPM better too.

 

Exactly.....now as for with a stock 350 I don't think you'll get too much out of it, but with a longer throw crank you'll not only pick up cubes, you'll get some tq and power

 

wow ok sounds good 6" rod it will be thanks for your help guys hay what about rings anything special? im pushin about 6psi

 

The differences between them will be minimal.

Because cubes = torque and power.
