Hello mate hows things? My Cudas still a big pile of bits slowly coming together. Johns Cudas dead and not going anywhere by the looks of it grrrrr. Suspect possible over rev or may just be simply because these INDY rockers are cheese! Apparently they're known for breaking! Not sure on spring pressures etc as the motors pete wisemans old one from the dart and we havent many specs on it. Hauser built it but doesnt know all the details. Hows the Cuda going? Fancy lending us your motor for the weekend?
