I haven't been on this site in a few days, we have a lot going on in BR LA right now. All of this is interesting. I prompted the OP to start this thread without realizing that there is not a big base of BBC guys on this board. I'm not a bigblock guy, but I do know the gen V BBC is the least desirable BBC platform to use for a buildup. The valvetrain is an issue, as well as the cylinder head architecture. Both of these are barriers to the traditional methods of building the typical warmed-over BBC torque numbers that would derive from a cam swap.
Do you change the valvetrain over? Do you swap heads? Do you just take the minimal gains from cam only while retaining the non-adjustable valvetrain?
The dynamics and principles are the same regardless; build more cylinder pressure, set the duration and lift values where you want to make power, and open/close the valves at the ideal times to support the intended rpm range, and proposed parts combination (vehicle/engine/trans/converter/gear/tire).
Chris Straub is a sharp fella. He may not be a snazzy web designer, but he can cam an engine. Most times the cams he specs are smaller than what's already in the engine, and after the cam swap, they make tons more power & have way better manners. Him and Scott Foxwell know what they're doing, even if you guys haven't heard of them before.
I'd be looking for a cam with timing comparable to this cam (in the mid 2-teens intake & low/mid 2 twenties exhaust), but on a tighter lobe separation angle (108 or 110) as this is usually indicative of earlier ICA so that the cylinder can fill to its potential.
With regard to comp, I'll offer this. Buy a billet core camshaft from them or you'll be buying another cam and entire engine shortly thereafter for that matter.
