header question Does anyone have any info. regarding the gains of going to a 1 7/8" header from a 1 3/4" header on a 402 with L92's??? Just curious of the swap would be worth the $$$$$$$$.

i dont think your gonna find many people who's switched from 1 3/4 to 1 7/8 as most will go 1 7/8 from the start on the l92 setups. and the other fact that this setup is still new. honestly id say the 1 7/8 w/ ls7 style (d port) flanges and big collectors from kooks or american racing should show you considerable gains over a traditional ls1 1 3/4 header. but would love to see a dyno comparison for sure. good luck

I appreciate the responses, I would like to see the gains as well. I just don't want to spend another 1K on new headers when the set I bought is less than 2 months old. I guess I'll wait to see if anyone else does this and makes alot more HP.
Thanks!
Thanks!

It is my understanding that the ls1 headers are big enough to cover the D shaped exhaust port. If the header circumfrance is bigger than the exhaust port, should shape matter?

Great question. I am wondering the same thing. Would Hooker 1 7/8 header's fit the L92 port design with out any flow/power problems?
