holy cow that's an oldy.......
I got a 69, whatcha want to know about yours.......
and how much to you want for your valvecover... it's in much better shape than mine

The drive is not a bravo.... dunno where you heard that one from.
In its day the drive was called a 120 drive, as all the drives where names after the HP of the engines.
basically its a #1 drive or Merc 1.

Hey jcsersca...how much "mid" in Mid-Michigan are you?

I am East of Muskytown about 30 miles and North of Grand Rapids at 43 miles.

Looks like an interesting project there and if we are ever around the area, would be nice to see.

I have a couple of those #1's...both on Mercruiser 160/165's.
