I have 2 engines for the Super Bee. They have both run the same ET. Both are 493s. The engine curently in the car is 14 to 1 with a dome pistons,it is 4.150 stroke, it uses 346 heads that flow in the mid 270s, cam is a solid roller mid 250s with .630 lift.I use 1.5 crane rockers with a stock sixpack. The ignition is a Chrysler chrome box with firecore wires. It has stock exhaust manifolds with no modifications and a Accurate 2.5 exhaust system, mufflers are Ultra Flow SS.

The other engine is a 12.5 to 1 with flat tops. That one has 906 heads that flow a smidge better. The cam is a solid roller that has slower ramps with the same .630 lift. If you want the specs call Dwayne I really can't keep them all straight anymore. Otherwise they are the same really.

The high compression engine never really lived up to my expectations. It has a lighter crank,more comp and a more agressive cam. Just a Dud really. I think the 906s are just plain old better.
