Lessee: you have a good block, 16 rods, 16 pistons, and need machine work anyway, unless this is a dingleberry hone and send it type of deal. Take everything to the shop and get it balanced and align honed with a cam bearing install= build confidence.
Where you gettin these extra 8 rods/pistons?
I got my '76 that spun a bearing, bad crank, messed up rod(s?), needs baked and cleaned out and new cam bearings, and everything else. It's just the block and heads right now.
I got the new to me '71, which is the engine I'm messing with now, that ran and drove until 6 years ago. Sitting in a guys garage on a stand since then. He drove it around in a 71 skylark it came from, and had it in a 4x4 truck.
And my exploded '70. Of which, probably the only usable parts left are the cylinder heads, exhaust manifolds, and aluminum intake I
just put on it.
I only have 8 rods to play with.
My original "plan" was to take a new/used crank I bought for my '76 motor (before the '70 exploded), and jam it in the '71 motor as the crank in the '71 motor had some scoring. It was never an "I'm gonna do it 100% no matter what" situation. After comparing both cranks, and along with all you guys banging your heads on the wall, I decided to not go through with that plan due to the potential catastrophic issues that could arise.
Now, if you refer to my post about peeking inside the '71 engine, it's in remarkable shape for being 48 years old. With the rebuild kit parts being delayed, that's another reason to just have the '71's crank machined. I'd have to wait either way. So, that's the plan now. Refresh the '71 with it's own crankshaft, new rings, bearings, gaskets, cam and lifters. That's it. It even came with a starter. hooray.
