If they are dead stock then it will be a snooze fest. We've tried to run a few Hemi engines on the dyno with stock distributor and stock carbs and they usually don't run very well. It takes a lot of work to find factory original parts that actually still work.
They used a stock cam in both same grind, headers on both.
On the 440 an Edlebrock Aluminium sux pack intake 3 Holley carbs not sure if originals or the replacements.
The Hemi had a non stock 2x4 aluminium intake but said it was close to stick but had both AFB and Holley 4150 patterns so ran 2 Holley carbs.
Both non ported iron heads. Think 440 was 906 and the Hemi were Mopar Performance but had original valves from an old Hemi.
Was he said 440 with stick replacement type poisons was 9.5 ish but Hemi was heavy forged and was in same neiborhood compression.
Stock Mopar Performance Hemi block they said was available since 1994.
Stated they wanted close to same compression ratio on both, same cam grind both and non ported heads on both.
Not exact but what they could do. Steve said the same heads on a 383 and was on the money at 335HP just like MA said it should be. But fell short of the 375HP on a 440 on the past
This time they worked on the 440six well.
