Unlike the 426, the Olds 455 has no limit on valve to piston clearance and when combined with the 1/2" longer stroke, much more duration can be used than with the 426. They came from the factory with the same rating but they are worlds apart in HP potential. It looks like only the 442 convert will make it down to G at it's current rating.

And with just a 5 horsepower penalty,the Dodge gets Edelbrock Aluminum Heads which are NO better than 1964 technology?

Dick, I agree with you. I'd say slapper bar cars are at say 9lbs. per cube start the class. Ladder bars add 50 lbs. 4 link cars add 50 lbs. let them all in. Slapper bars limited to 10.5", ladder bar 12.5" 4 link 13. 5.
What say you? Heads up, pro tree. Brodix spec head

Maybe have cars 82 and newer add 50lbs. Just a thought.
