I've had a '76 440 with an Ohio Crank 499" kit in it for 8 years now. That poor thing has has the crap beat out of it on the street and on the track.

Had a 180hp nitrous kit on it for a while that beat the ring lands out of one piston and broke the rings in 4 other cylinders. Lost 2 lobes on a cam and had to have it line bored. Had a balancer outer ring slip, causing me to set the timing too high for a weekend of racing. And on and on.

That engine has consistently put at least 500hp to the rear wheels. Not bad for a "thin web" block.
