Putting a Solid cam in a Hydraulic Block??

The 360 thats in my Duster now was built in 1994 & I have a dyno sheet from Bristol TN where the guy had it dyno'ed. It made 389 RWHP. Its nothing fancy, just a good running street motor.

72' 360 block bored .40
71' 340 J heads ported/polished
Mopar single plane intake of the M-1 variant, with some mild porting.
Mopar purple 292 solid cam W/commando rockers
750 Holley DP.

Keep in mind this was in 94' whem the motor was still fresh, but it still runs very strong, & it will turn every bit of 7000 rpm's (shift light set at 6700).
