2270 Deck Height and CR, Pistons sitting proud of the deck, how many shims is too many shims? Options

[vjb206]

Hey folks! I have the bottom-end of my 2270 assembled and spinning freely. Thanks to all who helped me get to this point!

To quickly recap: I bought the 2257 kit from AA Pistons (78mm stroke, 5.158" rods, etc.). And when I threw a P&C on for a test-fit last weekend, I immediately noticed the piston sitting proud of the deck height at TDC (negative deck) by about 2mm.

Before I overreact, or buy the wrong stuff, I thought I'd ping the community...

1. Is this normal for a stroker set-up?
2. Can you stack multiple shims when getting up into the .06 >> .09 range?
3. (If no-stack) What's the best place to have custom shims cut?
4. I recall Jake saying using large shims requires lots of advance, anyone have experience here? What am I looking to adjust for upon start-up?

Once I figure out whether or not this is normal (I.E. verifying that I don't have to backtrack), I'll get into the CR questions (just waiting on clear plastic from Amazon so that I can measure my CC volume this weekend) (IMG:style_emoticons/default/biggrin.gif)

Thanks!

The picture of intake port is from the moment of tear down and my comment was (this should be blueprinted and there should be no extra material to cause any flow turbulence) . You can see the port work on the RAT HAM heads.

The Windage tray modification was a RAT deal innless this Eng. was rebuilt after Jake built it.
No matter what you see the spun bearing. We opted for Tuna Can as it must have been oil starved at one point. It had a rear next to trans auxiliary oil cooler, and the decision was made to change that out to a front GT style cooler at PMB Performance

This Engen was in Oscars blue car and the guy that bought the car just wanted the body and sold us the Engen and trans. He was going to a huge Mopar and custom trans. His car is a spare no expense resto mod. He also did some great hot rods so that body should end up as a nice car.
