the tall deck is the same oil pump drive as a 9.800 bbc the tall deck needs a longer dist or the intake needs to be cut for the stock dist if you not down ?some thing is to short do you have a tall deck block 10.200 or a 9.800 block? like i said if you have a tall deck you need .400 more on the dist if a slip collar dist move the collar i cut dist down on the lathe and make them slip collars

just measured it , 9.8 , pump shaft and pump are correct but it is about .4 short! ??? is it easier to make a longer shaft or alter the dizzy,? what about the clicking when i primed the pump ? ....... mike.
