Installing a C-Notch on C10 PU - The 1947 - Present Chevrolet & GMC Truck Message Board Network

For the properly done drop of my C10 PU, I selected the CPP heavy duty C-Notch kit that comes with all grade 8 hardware. The frame cuts were done accurately and straight using a die grinder and then smoothing everything with rotary sander. Everything went without any problems and the CPP brackets fit beautifully. After all hardware was installed, the brackets were also welded to the frame. Finally, the frame was cleaned and painted.
I also installed a new Eaton TrueTrack posi rear and Wilwood brakes all around. The results were well worth the labor and expense.

nice touch welding it to the frame and using the HD kit. May be stronger then stock now! Looks very slick with the paint too.

Ekliptix: I noticed you are using the 700R4, Eaton posi, with the 3.73 which I will be using as well.
I selected the 3.73 as a mild performance ratio but hopefully would be somewhat highway friendly due to the overdrive tranny.
How has the 3.73 worked out for you? If you know, about how many RPM's do you turn at 60 mph?
