Are you FCuddy's buddy that picked up the 28-7 with the full race porting? I am guessing so since you quoted Bob's post but I have recently sent out a few of those so I just want to be sure who I am talking with. Glad you like it!! I said it would be strong . Just figure out how to harness it ie: clutching, gearing etc. Think outside the box on this one and you will be fine. I ran the .28's in truggies for years and they are more than doable, just have to gear them up and clutch them down to get them to work well. Alot of people struggle when they leave stock gearing and clutching in the vehicle and upgrade from a stock or modified .21 to a moddified .28. Keep us posted on how you do with it and thanks again for your business!!
