yea it does, its hard to navigate around, he makes the kits look like you slap em on and your good to go, little to no machine work required.... obviously thats not the case
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.

I spun a SADI core cam to 7600 a few times once, then it broke in half lol. I buy billet now.

I was aware that there is a small amount of big block fellas in here.. this is my first one... usually when I see cam suggestions, its all over the place, many times the thread starter doesn't realize what has to be done to the heads for high lift cams or they want a cam for its rough idle noise and hope for the best on performance. (enter ***** thumper cam) Since this forum doesn't seem to be chocked full of engine builders, I went ahead and looked elsewhere.
Ive searched for Comp cams parts being made in China, I have seen responses where they say they do not buy cores from China but from 2 U.S companies EPC or LSM which really doesn't answer the question if there Chinese billet cores or not, although I may tend to believe they are because Comp Cams says GM, Ford and Chrysler Also buys Cams from EPC or LSM and sadly most of us know where most of those parts come from, that makes those vehicles.
the search continues...

I used to work at Engine Power Components, their cores come from all over depending on the application, including the COMP line.

Im a dying breed in California, but "Made In America" still means more to me then price, Its disappointing how many items are made overseas now.

I'm not quite there, which may seem funny, as I'm in the Auto industry, but I buy alot of tools at Harbor Freight for instance. I'm all for quality stuff, especially where it counts, but to hell with giving the Snap On guy 30 bucks for a wrench.
I was going to buy something, milwaukee brand recently, based on it being Made in America. It was something I was going to have forever, and count on. Looked it up, flipping made in China... I think it was a Sawzall, idk. Pissed me off though.

I'm Awesome
The **** have really high quality stuff but there is allot of fraud *** stuff too and I don't know of any power tools made in US and even allot of snap-off is renamed junk.
Sorry I blew up off topic.
Here is my recommendation:
