408 Cam

Looking to get a 408 short block from Muscle Motors. Going to top it with a set of 308's from a 360/360 Commando crate engine(2.02 valves). I have a few cams lying around. What does anybody think about the old DC 528/284 solid? I have a 10 inch converter and a 4.10 gear already in my Demon. I want to get back into drag racing. Going to pull the matching numbers 340 out, so I can't hurt it. The car ran high 12's-low 13's with the stock 340, looking to get high 11's. Or should I just get something new from Comp Cams? I also have an old Ultradyne solid, about a 550 lift. Thanks.
