Compression?? L-92 heads I have L-92 heads on a 6.0 block using the new Diamond pistons for L-92 heads. My heads are milled .025 my cranking pressure is 160 lbs. What is the formula to figure compression ratio? Trying to get a idea what my compression ratio is. I was told about 10.7 to 1 thanks for any help.

The nice thing about my new L92 heads is they loves a lot of timing. The more I have added the better it runs also no knock issues even with a lot of timing & 92 octane. I think running a little less compression with more timing has sure made it pull hard. I will be running nitrous 2 stage again after I get a few more miles on my build which included Scat H-beam rods & all ARP bolts. One of the reasons I didn't go big on compression is because I will run stage one 125 hp stage two 125 hp total 250 hp. My times listed where with a stock block, stock heads & cam. I should run easy 11.10's now with better traction (MT DR's 305-45-18") new forged motor with a mid sized cam & weight reduction. SS Trailblazer 4320 lbs new weight.

nice camshaft you have should pull like a train,114l/c makes for broad power range and plenty of torque.
enjoy your new found grunt.
