:drama: Bring on the 500 HP low revving 318. :rolleyes:
They say it can be done, I'd like to see it. :D
It's coming to a dyno near you soon.:popcorn:

Had a chat to a friend of mine who built a 290 ci 273 (large over bore) with ported 273 stock heads and a big solid roller with webbers that went into a local circuit racer that he says made 458 HP @ 6500 Yes that's 6500!

That's 1.57 HP per CI.
