Maximum lift?

OK guys, I need some advice here. Quick rundown on my engine. 360 bored .030", J heads w/ 1.88 intakes, approximately 9.6 to 1 compression ratio. Stock 68 to 70 340 exhaust manifolds w/2.5" exhaust. Six pack manifold & carbs with a scoop sealed to the air cleaner. 4 speed (my choice of either a close ratio or an OD), with 3.91 gears. Street driven "play" car.

I've been offered a good deal here on FABO on a custom ground Comp Cams roller cam with lifters, dogbones, spider, etc. Here's the specs.

230/236*@50 110CL 4* advanced w/510/520 vlift (1.5 rockers)

I compared this with the cams in Comps catalog & it's close to an XR280HR-10. I had been looking at the next two smaller profiles in the same line. I had also looked at the Comp "Thumpr" cam with these specs.

Dur @ .050 .227/.241 .513/.498 LSA 107*

The guy with the roller cam also has a Hughes hydraulic cam with matched lifters that is about 2 steps above the 1928AL & 2328AL flat tappet & 1828AL & 2228AL roller cams that Hughes recommended. It has these specs.

230/237*@.050 with 515/535 vlift 110cl 4*advanced.

Do any of these sound suitable for my build? My main concern with them is that they might be a bit much as far as duration. People are always warning about over-camming an engine. These two cams are both very good deals, but I don't want to get the wrong thing just because it was cheap. Plus, the flat tappet is probably a bit better suited than the roller, but I kinda' had my heart set on a roller. AAARRRRGH! I hate trying to pick a cam. :cussing:

Help, please!
