Interestingly, Bryce's published flow numbers for the Mopar 220's was on a 4.125 bore so I expect the actual flow in the 4.03 bore 633 hp dyno 408 would have been a bit less than the advertised numbers.
On the LS I guess I forgot about the 427" Z06 motor....my bad but that one is kind of a special case that is few in number and only resides in Vette's. does Dart or someone make a 4.125" bore aluminum aftermarket block? I know there are a few iron ones. I have an 06 Trailblazer SS with the LS2 I may look at upgrading someday. Right now it's my tow vehicle
