pick one tr's 224 or comp xr275hr pix of heads
which one?
going in a 5.3 heads have been worked: .05 milled, larger valves cc has been unshrouded
7.35 pushrods
truck already has 3k stall in it with 3.73 rear end, will eventually have full compliment of bolt ons. Will turn around 6500 rpm at wot, looking for cam that starts around 2k rpm.
thunder racing cam: 224/224 .563/.563 112
comps XR275HR: 222/224 .566/.568 112
lpe ls1 gt2-5: 222/222 .566/.566 112
not a cam guru
ultimate goal 350/400 rear wheel

Those 3 cams are virtually identical, you don't need to be a "guru" to see that. There have also been numerous "success" stories from people running each of the 3 different manufactures. I've always liked Comp Cams. I have run several Hydraulic cams from Comp in the past in different cars, and I have a solid lifter cam from Comp in my '57 Chevy now. When degreeing in the cams from Competition Cams they have ALWAYS came up "right on" the money. I've run Crower cams and also a Competions cam in other small block Chevy motors (non-LSx Gen I motors) and have had their Cams come up off as much as 6 degrees! I've never run a cam from Thunder or Lingenfelter, and I'm sure they are great products...but I CAN tell you that Comp Cams is definately a GOOD choice. Do a search in the internal engine section under Cam Degreeing and you'll see what I mean.
