Plenty of options besides Zippers. If ya love grief, no customer support and attitudes, go to Zippers. If ya want something other than that, look elsewhere. The SE 251 is a good bolt in cam. Your dealer, if they're capable enough to assemble top end parts (they better be for this new "campaign"), can do it at the time of your "Product Enhancement". If you're looking for better performance than that, speak with a good engine designer/builder about what you're trying to accomplish. If he's any good, he'll listen to you and be able to recommend a package to meet your needs. If he doesn't, you're at the wrong place.
I use CR 595 cams from CycleRama. They did my heads and designed my engine for 9.8:1 CR. A much larger TB is required if you're doing substantial mods. If you use the SE 251, the 50mm TB should be adequate. I see you have the FatCat already. So you have many options.
Who's doing the work? If it's the dealer, it's important you and he are on the same page. But Zippers would be the last place I'd look personally!

Good luck with your mods!

Hoist!
