I was dangerously close to the Ritter deal in 12..... but was convinced by a couple to go the R3 route (were still in the system in 12) especially since I work at a dealer. Later through the small block brotherhood I learned why. A lot of folks were guinea pigs for his (Ritter) venture. To be fair there is a member here in Kansas that has his aluminum piece going and it's alive. There another built at Trumble racing engines recently with the new Ebrock heads up and running. Light at the end of the tunnel I guess, but not sure I'd risk it. Brian at IMM has had one on order to do a build. I'd like to see more successful builds so there is a viable option. As for me.... I'm probably nearing the end of this hobby. If I destroy the 9.20 piece in the car, I do have a 9.0 piece here I could play with. I'd just have to procure the dry sump tank etc... I'm not making huge HP so my stuff "should/hopefully" last a long time.
