My oldest son wants to have his 350 gone over for his 71 chevelle. It is a 350 with a TH350 and a 4.11 rear. He asked me if he should have the factory 5.7 rods rebuilt or go with 6.0's. I told him in a 6000 rpm street motor that goes to the track for fun, it would not make a difference. Engine builder told him 5.7's are fine. Any opinions? Thanks. graemlins/beers.gif

Never heard of a 350-357 with 6 inch rods, only with a 383, but of course Im no expert. I think I would opt for the 5.7's, in fact I did opt for 5.7's in my 357 last early spring. smile.gif

6" rods are great for a 350.. They allow for a lighter piston and help the rod angle. You can buy 6" H beam eagle rods for 325.00 with 7/16 bolts at http://www.cnc-motorsports.com/product.asp?ProdID=8089&CtgID=8077

5.7

Eagle SIR 6" rods are the same price as 5.7" rods (mine were $220 but I've seen them for under $200). 6" pistons weigh a bunch less than 5.7 pistons and the cost is the same. SIR rods weigh less than factory 5.7 rods. The engine will rev quicker with the lighter pistons and rods.

id like some more information on this as well please
