Ryan, i see Tom hasnt been here yet... so i'll chime in a lil bit... a 383 is a good all around street engine. can be tame enough for every day driving, and can get a lil crazy for a more performance oriented application. my personal combo will include a compression ratio around 10:1, a Comp Cams XR 276, and a set of Vortec heads. i shouldnt have any problems running this setup on 92 octane, even with its 8.2:1 DCR.
