If and 806 is a hard starter then it is time to pull her down and do a rebuild On the head and block . Valve resshion will cause hard start as this will drop the comp. ratio . When a D361 is wright they will start down to near 0 with out either . Now one thing you should know is that rebuilding a D361-407 is not for the novice mechanic as it has it"s quirks and i have seen way to many rebuilds done by guys that tell me OH I CAN DO THAT no problem and in anywhere from a few min. to 50 hours they throw a rod out the side of the block and bust the crank. Over time the block tweeks and when i do them i get them line BORED and decked and cut the counter bores then set the block up in the boring bar and bore off the center line of the crank and install .010 over slevesand PRESS them in not drive then ya must use a bore gauge and check for wrinkels and hone to fit each and every piston to it"s bore . THen ya double cross your fingers and grit your teeth and do three hail marys and if it makes it past the 50 hour mark it just may live 10000-20000 more hours .
