1 7/8 headers?
1 7/8 headers? Guys I have 1 3/4 Pacesetters on my car right now. I will be putting in a 383 in the near future. Would it be better if I go to 1 7/8 headers for the larger motor? Thanks.

i would say not necessary unless you are going with a good flowing set of heads intake and cam. even then they may move the power band higher in the rpm range than you need, unless this is mostly a track car.
Its a weekend warrior. But will see some track time. Motor has a GT2-3 cam, LS6 heads that have been worked. I also have the Fast 90/90 already which I will be putting on the motor. I'm eventually going to put either a Maggie or ProCharger on there also but not right now.

The 383 will benefit with the larger headers. Your current motor will likely only see slight gains above 5500 rpm and may lose low-end torque compared to the 1-3/4" headers.
i have pacesetters and i also have plans to do a 383. if i do go with the 383, i plan on running ARH 1 7/8 headers. so yeah, i would go with some 1 7/8 to get as much out of that setup as possible.

I'm confused. Are you aksing about headers for the current motor or for the 383? Are you planning on using the GT2-3 cam with the 383? That is a very very small cam on a 383.

when you say "worked" heads what do u mean? ported? milled? hit with a sledge hammer?
it's hard to give you a good answer when you give vague discriptions.
if its just ls6 heads, low boost, and that small cam, i'de say the 1 7/8 headers are too expensive for the gains.
however if you are running stage III cnc ported ls6 heads, high boost, and a nasty cam then i would say yes 1 7/8 would be worth the extra green.
