Cam choice questions, sorry long post

I like the short rod combo in this with the tunnel ram. But, I'd go up .5 point in static compression with that intake. As far as the cam goes, I'm not a big fan of hydraulic rollers. Either stay flat tappet hydraulic, or step up to either flat tappet solid or solid roller. I don't run Hughes products for my own reasons. Personally I'd be pushing for a solid flat tappet if you want the best results for minimal spend. Anything around the 250° @ .050 area will make plenty of steam provided the heads are set up properly. As far as hydraulic cams - the Engle K-7HYD, Crane 684571 or Comp XE285HL in that order. As far as solid flat tappets - I like Stroker's recommendation or Crane 681321 or Comp XTQ286S-8 but I'd run the 1.5 rockers with any of them.
