Exausting question

[waterbum]

Will 3" inner exaust tubes choke big block power on top end? Gill type exaust.Merry Christmas to all!!

Depends dude! what are the details on the motor? a gil will do better than a stock exhaust but if your rig is an aluminum headed roller deal go for a imco, or eddie marine deal or better yet tube header like CMI's

The engine is a slightly modified h.p.500 carb version.

3" i.d. dual will easily support 600 hp if it's got headers. So most likely, no.
