Check my math plz
Check my math plz Using 9.025 as stock deck height, the pistons are 1.563 CH. (Thats what Summit says, I was off by .020 in my calculations) Anyway
1.563+1.742+5.7=9.005
CH CT RL*
9.005-9.025=.02
Piston is .02 in the hole????
I will need around a .02 gasket to keep ~.04ish quench?
The only one I can think of that close is the Mr. Gasket .026, or the stock Impy gasket. Is that to thin for a possible 200 shot?
*CH- Compression height
*CT- Crank Throw (Storke/2)
*RL- Rod Lenght

The math looks fine, Swing, as long as the dimensions are all verified. When the GM engine plants are machining blocks, they tend to cut as little metal as possible in the interests of time saving, so blocks can end up above spec. height. On the other hand, used ones can be way below! A buddy of mine had trouble hot starting his home-built 350. Turned out the block had been decked so far, the pistons appeared to be hitting the heads just cranking with the engine hot!
Moral of the story: Always do a test assembly and check for yourself.

Thanks. I will still check everything, I was just trying to run some numbers. I am worried about using the thin gasket. I plan eventually spraying upto 200.
I am going to have to find a new block. I finally pulled my heads from the motor that was in my car. Guess whats stamped on them. 040!! I already bought 030 pistons!!
