looking to step up from 306
I have had my 383 running for over a year now. I think I am ready to step up to diffrent set up. it is currently a 12.5:1 cr forged pistons, rods, crank, stock casting heads that flow 289I 199E at .600, com 306 with 1.6 rr, 1 3/4 long long tubes, stock tb. that car makes 411rwhp, 400rwtq. I made a few trips down the track. 3 to be exact on street tires it ran 12.2@ 118 with 2.2 60ft the car weighs 3695 race weight.
I am looking to step up the cam I would like to stay under .600 lift. Because I dont want to swap springs. I am not scared up a custom grind but I kind of like the idea of an off the shelf because the are proven. thank you for any andvice or recomendations. T

a 306 with 1.6 rockers is 230-244 .544-.576 112
a 236-242 with 1.6 rockers is 236-242 .555-.576 112
I might be missing something but it does not seem like it would offer large power advantages.

But your comparing two different cams. The 236/242 is a XE cam. Go ahead and call Comp and ask what the difference is between the 2 but I guaruntee you that they will tell you the XE cam will make more power than the 306. I don't know exactly how the XE works but it has something to do with faster ramp rates and various things like that. Also, XE cams are supposed to produce for vaccum at idle compared to other large cams.
