zz4 cam vs comp cam

Hey guys Iím new to the forum but Iíve been researching on this website for a while. I joined because Iím building a motor for my 91 c1500 rcsb and I wanted to get some advice on cam choices. The motor is a stock 99 350 with the exception of some mild porting, ls6 springs and comp 787 retainers on a pair of 062 Vortec heads for more lift. Iím trying to decide between the zz4 cam or the comp 08-304-8. The specs on that cam are .210/.220 @50 .500/.510 lift on a 114 lsa. The truck is my daily with mostly highway driving and occasionally pulls a small trailer. I want something that gives a decent amount of tourqe but has a power band up to about 5500. The person that owned the truck before me put a Stock TBI flat tappet cam and and 810 heads on it so that it would work with the stock computer and intake so right now it falls on its face at like 3200 rpm. I apologize if this has been covered before but I couldnít find anything on this site about the comp cam and wanted to know if anyone had any experience with it. Any advice and help is greatly appreciated!
