If you were to ask Roger about a cam for a heavy ass SUV with a manual trans I’m sure he would be full of answers. The guy is super smart. He designs/ engineers their cams. But I understand your time issue too.I remember reading your review on Vinci awhile ago and it stuck in my mind. I think I'm fairly sold on using the 224/228 I have and then getting with Vinci for a custom cam for my Silverado where "Max power" is more important to me. Plus I don't want to wait for a custom cam. I think I can have this thing together sometime next week/weekend depending on my choice of what to do with the heads.
Also on cam consideration, it's difficult to find much info on cams for something heavy and stick shift but in the short time I had the 224/228 in my Silverado it drove very well out of boost. Plus it sounded cool
