: What's the compression on a stock LT1? teardropT60 03-16-2010, 12:29 PM Secondly, I was looking at some head gaskets for a future project and found that there are a ton of different gaskets one could get!!! Over a dozen atleast! I thought that was alot of different choices for something I would have thought would be really simple. robs1988 03-16-2010, 01:41 PM Different gasket thicknesses effect compression by raising or lowering it. Many things go with this in a performance application; rods, rod length to wrist pin, piston choice, location of the compression ring on the piston, machine work on the heads, head choice, block decking, etc. vetteoz 03-16-2010, 02:44 PM Different gasket thicknesses effect compression by raising or lowering it. :iagree: Stock LT1 ( Vette ) is 10.41 chappy 03-16-2010, 03:29 PM Standard engine i beleive is around 175psi or so, but i dont know exactly what the spec was on those.
