360 Crates

Hey Craig;

Any create engine from anybody should be torn down and inspected. (IMO)
The best dyno run I seen on the older 360/380 HP create was 410 HP with what MoPar recomended to attach to it. (750 cfm, 1-3/4 tube headers, etc..)

Big blocks weight can be drop very well. Down to a S/B. But you can drop the S/B weight further. Then stroke to 400+.

Tough call. It is really down to what you want. Not a thing more.
