273 commando Build

update ... update ...
I put on at least 500 miles on the rebuild and just did a oil change and filter .. no silver at all in the oil on my 273 build and it is running Great ! NO LEAKS NO ERROS ALL HOME RUNS ! .. this 273 is making way more hp and torque now after the fresh rebuild and port and polished heads this time around . and will probally make even more after is loosens up some . very very happy ! the 273's rock !
