The mild grind keeps normal drivability but still increases performance. Wild gives max performance but you sacrifice everyday driveability (rougher idling, may not pass emmissions). As for incorperating cams, it's defiently better if you get a cam from the same model range (86-89 carbed, 86/87 EFI, 88/89 EFI) so you know you can get the most out of it.
As for payment and stuff, I haven't decided yet but I will talk it over with Geoff and see what is best for both of us. My responsibility would be to get the guys together if we do the group buy and stuff but I'm not sure if that includes collecting all the payments and cams too. But it doesn't really matter to me since he's close by so I don't mind helping him out a bit by doing some work for him.
