not sure about the 8 but I have seen it done and provided some assistance to convert a 7 to 7A. it required new engine mount, new gear and gear brackets for the mains. some adjustment of the cowl to spinner interface was required and some cowl fiberglass patches where the gear penetrated. it's a tight work space to drill the main gear brackets but doable. upside was 1/3 cost for insurance for an 7A model and easy landings.
RV-9A, Tip-up, Superior O-320, roller lifters, 160HP, WW 200RV, dual impulse slick mags, oil pressure = 65 psi, EGT = 1300F, flight hours = 600+ for all
Simplicity is the art in design.
