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!

Yes, agree with post #18 from the ninja above.

An example is the 2615 we are starting to build. Some of the particulars are: coated pistons, DFL on skirts, starting with brand new bare heads with modified & coated exhaust ports & combustionchambers/valves, special/custom valve train components (including cryogenic treatments), "nickies" cylinders, custom dual pattern "big" cam with more exhaust duration, etc, etc. Lots of time invested in researching and developing the plan before starting to acquire the parts and starting to machine parts.

As already mentioned, stroker motors are a lot of fun, but lots more work to get right.
