273 commano on the dyno wooooow

That is sweet. It pulled pretty fast too. In the description it mentions that it is a FIA motor which is a NHRA Super Stock motor with 450 BHP at 7400. That is one trick piece, would take a lot to make your garden variety 273 to make that. Back in the day my 273 ran 14.33 at 101 in my 68 Dart. It had 8 to 1 compression and I wish I had been smart enough to build a better 273, I think I could have had a 12 second 273 which would have been cool. Even with no compression mine revved to 7000 but had no low end torque. Thanks for sharing
