Caddy

Bored the cylinders .050 over, to 4.350". Installed bronze guide liners and opened the valves seats to fit larger valves. After I did all the block prep, (Grinding and De-burring) I had a shop install the cam bearings. When I got everything back from the machine shop I finished up the dirty work with a light port and polish with some bowl work to compliment the larger stainless valves. I also enlarged the push rod holes to facilitate larger 3/8" chro-moly push rods and smoothed the oil drain-back holes. 

Assembly of the bottom end was pretty straight forward. I purchased a new .010/.010 Crankshaft kit from PAW. All other parts were ordered from the Cad Company and Summit Racing.
