piston deck ss engine

Yes. The .004" difference probably would be insignificant otherwise. Next time its down for a rebuild, get the deck heights equalized.

I am not sure you can run a deck above block. That is the way the rule use to read.

If deck height is suppose to be below deck that's what it has to be. Even when it's suppose to be above block it has to be above.

At least that's the way I remember it.

Oops. I didn't remember the legality of that issue. I never had a plus deck engine like that. Better find a way to make it a minus deck engine. If you have rods with the small end bushed, it might be wise to rebush them and offset the pin bore a few thousandths. Otherwise, it's block time again.Best wishes on your project!!

Since we are talking an SS engine, just deck the pistons.

Guys , That plus deck , minus deck rule had been rescinded 6-7 years ago.
I remembered that, but I called the guys at Rick Watters to confirm.
They build them either way as long as the math adds up, and have been for a while.
