They seem to be okay. The owner has never even driven the car yet, but, .030" over 440, 3.75 stock stroke. 9.9:1 compression, six pack, 590 HP and 574 lb-ft all before 6,000 rpm. 574 lb-ft @ 3,500 rpm and 502 lb-ft @ 6,100 rpm. I think it will move the Road Runner if he ever starts and goes someplace with it. Busy making it pretty.
