I only use cloyes chains in my engines. Ran the billet race roller sets in my 548 and 565. Even saved one of the take out chains to go in my street car.

Mark said, there is something off with there recent pumps. Multiple pumps feel notchy, they should be nice and smooth.

My Daughter dropped off the ring set and rod bearings. Now the Mahle pistons now attached to the Molnar rods and the 330 forged crank is heading to the other shop for internal balancing.

So the saga continues, the machine shop called and gave me the number of the balancing shop. He said, they could not internally balance my crankshaft. I called the guy, he said they didn't have the capability to add Mallory weights, WYF? Really, this is the shop you sent my crank to for internal balancing! I told him, weigh my pistons and rods, they are about 600 grams each. This 330 crank was supposedly balanced with heavy 18cc dish Speedpro forged pistons on heavy stock rods. I told him to please check first, if anything, weight should need removed from the counter weights. He was going to check, I left Wayne my number🤔.

Weight should only need to be removed for externally balancing. If it is internally balanced, all of that offset outside the engine STILL needs to get INTO the counterweights. So granted your pistons and rods are a little lighter, it may still not be enough to meet the external weights.

It should be 600 grams lighter.

 

[olds307 and 403]

Actually the pistons and tods are 400+ grams lighter. I will talk to them at the end of the week and see what they found.

So all 8 pistons and rods are less than 1 lbs lighter total? How much is the counterweight outboard of the engine?

 

[olds307 and 403]

Good question, the counter weights aren't super heavy according to Mark Remmel. Not sure how to accurately weigh one, I have another 330 crank, I could try to weigh. Like I said it was supposedly balanced for much heavier pistons and rods. I think the Speedpro forged are even heavier than stock pistons. But if it was externally balanced, that doesn't mean squat. I will call them this afternoon and see what they found.
