How do I know what size rod is my 350 with out taking it to a machine shop?
Thanks

 

Where is the rod, still in the engine, still on the piston, what?

Chances are its a 5.7 rod, thats whats in there stock and most people dont go to the trouble to change the length.

 

If it's a stock 350, then it's 5.7" rods. I think the only other rod that'll work is 6.0" rods, but they would have been put in by someone. GM never made them for a 350. Is that what you were asking?

Yeah the rods are still in the engine I was needing to know cause I am building or well having built another 383 and I just got to wonderinf about if there was different rod legnths factory from GM.
Thanks

 

Well if its just stock 350 rods, they are 5.7" long.
