Quick Check on my Shortblock before buying the Pistons So here is what I'm planning on running on my turbocharged LQ4 shortblock with 93 octane.
LQ4 6.OL Ironblock bored to 4.03
6.100" Connecting Rods
Stock 3.622" Stroke Crankshaft
stock 317 heads
the compressed thickness of the gasket is 0.051"
Mahle L92-LS3 Flat Top Pistons 4.03" Bore, 1.314" Compression height, -4cc volume, 4032Aluminum
I'm coming up with a deck clearance of -0.015" and a compression ratio of 9.53:1.
What do you all think?

Yeah after sonic testing a bunch of 6.0L blocks I stick with 4.005" when ever I can. Mahle offers that 2618 piston in 4.005", and 4.070". There is nothing wrong with the 4032 piston either if things are right. Im selling the 2618 mahles because when I orderd them I wanted 4032 alloy.

Sorry buddy they sold last night. Wish I knew you were interested. Been for sale for awhile nobody seemed to want them then it blew up today could have sold them 5x lol. Give me a pm or text I have a set of .005" Autotecs I might get rid of.

Ok I did a little more research on the stronger 2180 aluminum pistons and found some from Wiseco that would give me a slighly lower c/r for about $150 more so I think I'll go with those.
