I am in the rebuild of a LT1 torquey kind of engine.
I will not be turning over 6200, and probably only reach 6200 in a blue moon.
No NO2. No boost. No stroked.

I have obtained some Speed Pro Diamond Digital Profile pistons (in sub line), and was wondering if anyone has used these before and had any problems??

And if so, what compression were you running at?
And could one raise their comp above stock without any problems, with all things considered; 3.48 stroke, and ***374 gm ported LE1 heads, and raising comp ratio only by using different head gasket ?

I am selling them. .030 over Speed Pro Hypereutetic with coated piston skirts. With re-sized 5.7" rods pressed on and rings (5/64, 5/64, 3/16), +5cc, including rod bearings.
OMG.. I didn't know they were so popular!
