1'3/4 headers vs 1'7/8
 

wondering how much power i might be leaving on the table running the 1'3/4 headers on my 402. Its an all motor 402. Tfs heads and 239/242 .605/.610 lift cam. When i had it tuned the tuner suggested i step up...

give Allngn a pm.. he has a 402 and has results going from a 13/4 to 17/8. i think ron from vengeance also has info. with a big motor like what you have, i would defintely run 1 7/8.

I couldnt find a member by that name. help locating him would be appreciated
