I built this for a lady's 71 Duster. Her old 360 was a turd. She also requested it "sounds good".
8.8 to 1 using speed pro H405CP pistons
2.02 1.60 stainless valves
Stock replacement rockers, shafts, and pushrods
J heads with a little pocket porting
Hughes 2336 Whiplash cam
Performer intake
Recurved old Mopar Performance distributor
With my 750 Holley HP it made
353 hp
388 ft lbs
Using her 600 Edelbrock it lost about 10hp and torque.
Ignore that little curve at the beginning of the pull. It has something to do with loading the dyno.
