Rod weights - Engine Balance
For whatever reason, I blew up a piston and bent a rod in my 383.
5.7 rods, 4.030 Hyper pistion.
This is not a race motor, its in a Jeep street machine that will probably never see 6000rpm.
The crank is internally balanced for the assembly that's in it now.
I need to replace a rod and a piston. How far out can I go on weights before it is a problem?
I weighed the old rod, 588 grams. If I put a lighter rod in, say 558 grams, is that going to be an issue?
Keep in mind, this is a patch job, and were it a race motor I would be putting in all new matched components.
