We are newish to the world of A7s but having built a trials special over lock down and undertaken a few trials in recent months including the excellent Dave Wilcox event over christmas we have become quite keen. We are a husband and wife team and share the garage duties mostly on our regular Thursday evening date nights. Our special seems to be a good strong build with plenty of ground clearance but our almost standard engine is leaving us a bit short in the power dept. I would be interested as we have just started to build a new engine what the best mods are for trials? So far we have procured a pheonix crank and the main castings crankcase and block. We also have the pheonix crank and the rods soon to arrive. So far we have bored the block out in our little workshop using the milling machine to about 57mm and reshaped/ported the inlets to the 1"sq. I have plans to regrind the valve seats and reprofile the valves a bit 45deg and 30deg as per standard practice. Now thinking and interested in cam, carb, flywheel,clutch and head choice. Engine is a 34 Mk1 ruby engine.
