Default Follow-up...

Tony and I did a leak down check and it appeared tight as a drum. No significant leak down. We also did the compression test again with his gauge and came out with 140-150 readings. Perhaps I didn't let it crank enough times. Tony felt that based on "seat of the pants" driving measurement that I still probably didn't have the compression level that the engine needed to really produce that kick in the pants acceleration. Talking to Keith Craft to get his input on what I should do. BTW running an Isky cam with 250 duration at .050 and .525 lift. Car has the Shelby American aluminum heads with 82cc chambers. Don't have much info on the TRW 10:1 pistons so would appreciate any comment there. Hoping not to get into the short block except for maybe a new cam. Hoping to mill the heads and stage II port to see if I can bump up the compression and horsepower.
Thanks!
Scott
