Quote: That would be using the 6.358 stock length rod. To run the .990 pin version, you would have to bush the small end of the rod. Bushings are available too.
I've had a few PM's about compression ratio with the flat top pistons. Zero deck, 9.9cc composite gasket, and a 4 cc valave pocket figures out to this:
84 cc = 10.03 to 1
88 cc= 9.67 to 1
Is that with a 4.15" crank? Seems kinda low to me.
I guess my car will be a street motor, rarely seeing >6000 RPM, so I guess I can run the heavier (850g as as opposed to 790g) stock length rod w/the bigger pin and bigger rod journals. That way, I can use a 440source crank w/o having to turn down the rod journals to 2.2".
But racers would want to run the lighter components, but I guess they'd be running 400 blocks anyways.
Let us know when the pistons (for the short rods) become available! I need to get my block squared (to determine the true deck height) before I can order these pistons.
