The 296 looks like the same Pat kelley had in his 350 in his 67 elky and it ran 11.50`s. I would think that would performa better in your 383. That 304 mega you have in your 355 would work pretty well in the 383 as well. I know a guy who ran that same set up but less compression and it ran hard. He never had it to the track but he beat a 11.90 car on the street.
Which cam?11.80s possible
Building a 383 right now with about 10.6 comp,old set of sportsman 2s with 2.05-1.60 bowl blend 62cc.Vic jr 750 dp,1 3/4 headers with 3" full exhaust.3500 stall,4.56 gears with 29x10 tires.3360 race weight.Basically taking my 350 combo with a 383 shortblock.Now the question which cam, comp cams cs-296AH-8 HYD 246 253 .050, .510-.507 lift 108 lsa or solid cam xs282s 244-252 520 540 lift 110 lsa.I have 1.5 and 1.6 rockers to choose from also.I kind of want to stick with a hyd because of a better chance of not wiping out the cam.Alot of horror stories with a solid cam not breaking in properly.I don't want to take out the inner springs either.Anyways trying for 11.80s is it possible with the hyd cam.Anybody running a hyd cam in the 11s without some expensive AFRS or some aluminum heads.

do a search on the 294S. There are a few guys on the camaro board that have run that cam into the 11`s. your 304 mega should be enough if you wanted to stick with a hydraulic. I remembered another guy I know with that cam in a 327 that ran 11.70`s in a 69 chevelle.Has anyone tried a xs 282 or a 294s with a similar combo running in the 11's
