With my experience with my 383 build I make power/torque with less cam and at lower rpms than my 350 (355) counterparts...Thats just a general statement, but I run stock ported LT1 heads with 2.00/1.56s and a 226/234 cam...I make peak power at 6300rpms and run a 3600 stall/3.73s...Most of the time to run what I run with a 350 set up, its got more cam and consequently moves power and torque farther up the rpm scale, requiring more gear/converter...383s tend to make more power/torque under the curve at lower rpms...Not spinning this thing to the moon has surely helped my motor last for 12 years, not to mention having a big time bullet proof bottom end with a Callies crank, Oliver billet steel 5.85" rods, and JE pistons...Just my .02...

On a local Mustang Dyno it made 385/375 thru my old Borla cat back... I've since added 3" TDs and ax X pipe and haven't been back to the dyno yet...My sig times/mph were made with the 385/375 numbers...But I've out mph'd people with dyno sheets claiming 420 rwhp, so I don't hold a whole lot of faith in dyno numbers...I just use them to get my tune right...
