.060 Piston Recommendations?
I'm looking for a set of .060 pistons for a roughly 550 hp stock stoke 440. Most of what I've seen available is .055 overbore. Does anyone have a suggestion? Are Probe srs pistons any good?

Slice, did you get the block bored out already? Did the machine shop sonic test the cylinder walls? Going .060 over is a lot and makes the cylinder walls pretty thin.There are special cements that can be used to partially full the water jackets,but is recommended for a race only engine.

Slice, 67GTX is right. Bring the block to a machine shop first. Have them clean the block and check for cracks first. Have them check the cylinders to see how much they need to be taken off the bore, I would go for only what is necessary. If too much is taken off the walls they can actually flex, causing a loss of piston ring sealing and therefore power loss. See what the machine shop says.

Sounds like a bad place to start. Think I'll use another block. I have a 78 block running in the car now. I think is .030 over. I liked having the car up and running while I worked on the other motor, but I guess I'll pull it and start fresh. Thanks for the valued opinions.
