What do you guys consider to be the best header preformance wise for the 400? How about the best bang for the buck? I was hopeing everyone could comment on what they have and their engine output and if they were happy with the power gains and the construction of the headers. I was also hopeing someone could comment on the ultra-cheep dynomax headers. Are they crud or worth having for a heveily modifyed 400? I was considering geting a pair but they said they were for low and mid RPM range gains. Do you think they would be crud for a hevily street modifyed 400 that revs to a max of 6000 RPM compaired to other headers?
Hedman works good for me!!!..I have a set of hedman long tube headers on my 351M. It runs well, like 13.30's in a 1/4 all day long. A daily driver too, but i thin the price for them was roughy like $280...
I've got a set of "Cylcone's" from Hedman that have been on for about 18 years. They still looked so good a couple of years ago I had them ceramic coated.
