Has anybody ever done a dyno test for 440 a body headers,600 hp level?or switched from under chassis to fenderwell and seen a lost or gain

never did a test on different types of headers...our Duster had a custom set that could be called fender well exits and made tremendous HP..
just recently I had my 499 on the dyno with Doug's headers...they are fender well exits for my B body...great HP on pump gas...broke in at least 700hp on pump gas plus only 10-1 compression..
