Nope, SBC's in big numbers and darn few big block Chevy's. A few 100,000 mile Fox Mustangs that someone threw a blower on to run 11's ended up blowing steam out the exhaust when the head gaskets gave up. I don't remember ever seeing a Ford, Olds, Pontiac, Mopar or AMC scatter it's engine on the track. One Thunderbolt replica had it's rear end lock up at the 1000 ft mark and slid through the lights backwards at 100mph, one Ranger bodied tube chassis race car launched hard off the trans brake and slammed to a stop when the center section of his 9 inch blew out, and one Charger blew it's clutch or flywheel on launch and took off part of the driver's foot.
