hp gain ??

I have a 94 firebird with the 350 lt1 in it and was wondering what kind of hp gain should I expect from a .030 bore. Thanks

This guy doesn't know a single thing about whats going on. He is having his motor "rebuilt" but has no idea what the guy biulding it is doing. Like I said on his other post, he needs to really do some research and see what he wants to do to his motor, as well as find a competent builder who won't try to blow smoke up his bum with promises of HP increase through bore change.

Boring a motor over is only to clean up the cylinder walls. You may see a slight HP increase like maybe 3 or 4. If you really want to see HP gains put a big cam in there and get your heads ported or get a good set of aftermarket heads.
