Stage 1 cam will be ordered tomorrow. what all needs/should be done machining wise to swap pistons? just curious what the labor and machining costs will be if i decide to go with coated HD pistons aswell.

Id almost lean to the new international pistons myself, with the new bowls.... They are a direct replacement.... You could always have them coated yourself. I send all of my stuff to swain tech (pistons,exhaust manis, hot pipes ect...)

The International pistons are only avaliable in stock size, no oversize options yet. It costs about $30 a piston to machine the bowl of a stock ford piston and whatever the coating company charges.

If you wanted to stay stock size then would it be ok? Or do you need to start with an oversized piston on a used motor?

It should be fine, and no you don't need to start with an oversized piston unless you had to clean up some damage.

Only need oversize pistons if the cylinder walls need to be bored to remove scratches or ring marks.

so if the cylinders look good, what all should be done with the engine out? Balance the rotating assembly? what do bearings seals etc cost?

White_monster · Sep 2, 2012

Ya balance the rotating assembly. Bearins and stuff for the short block are pretty cheap, not sure on an exact price.

Swain tech has some awesome stuff at a great price.

And I can totally speak for their coatings... I know its not a diesel, but I coated the heads and pistons in my snow cross sled and have been able to jet it way lean and hold it wide open to see EGTS of 1350+ (which is wicked high for a sled) and the pistons have held together without a hickup. Looked into the cylinders with a scope at the end of last year and they looked great after two years of abuse. Any consumer sled or snow cross sled with that kind of timing curve and jetted that low would have melted down within 1 ride
