^This and...

The 427 LS7 is used in the new Camaro Z/28 and the Z06 Corvette. (Dry-Sump) Also sold as a wet sump crate motor too.

The 396 is a LS3 block that is found in many trucks, SUV's, Camaros and Corvette's.

The 350 is also uses the LS7 block but has a smaller crank.

All the above motors have been run for some time in the hot rod street car world.

90% of whey they are not street legal is due to the removal of Emissions equipment and the crash safety equipment. I.E. On the Camaro's the stock hood is one of the cars crumple zones.

No clue on the Fords or Mopar's...
