I got a 5.9 Magnum that I want to put new rod and main bearings, along with rings, oil pump and timing chain. I just want to freshen up the engine before I install it. The cam and heads are stock, but the pistons are .040 over sealed power pistons, and the rod journals are .010 under. I got the engine last week out of the u pull it, so I dont know the history of it. The truck I pulled it out of had a digital mileage setup, so I dont even know how many miles were on the truck, much less the engine. Only thing I do know is it was a 2500 and it didnt seem to look like it was abused super bad. Visual inspection of the bores look fine, still have the crosshatch in them, and the piston skirts dont have much, if any wear.
Anyway, I am worried I should change out the rod bolts. The pistons are pressed on. Most of the aftermarket rods are full floating, so I cant really use those, with the current pistons. And I want to avoid the costs of a rebalance also.
So, do I really need to worry about the rod bolts? Right now the engine is just going in to get the car moving. But I will push it some when its in. Probably no drag strip, but who could keep from hammering on a magnum smallblock in a Dart Sport?
If I should worry about the rod bolts, what would be the cheapest route? I gotta save money for other parts of the car. If I get something like the EAGLE press fit I beam rods, will I have to have the rotating assembly rebalanced? That may not be the cheapest, but I think it would be the best route for the money, as long as a rebalance isnt required.
What would everybody do in this situtation?
