Most of these engines make great power on the dyno but would never run the number at the track. That would be a real challenge. Run them on the dyno then put them in cars and run them.
There is a member here that has a 318 build that was used in the EMC 2010 contest that runs quite well. Also our 2009 471 engine which made 683 hp on our dyno with a single 4150 went into a customers Pro-touring '69 Charger and put down 587 HP at the hubs--runs slow at the track though with no 60' and a TKO tranny that you cant grab 3rd with--runs mid 11's @ some stupid MPH.
Also might ask Brett Miller also a member here what his 2011 EMC engine ran at the track in his car.
