I have a 160 GMC straight 6 in my 1968 thunderbird tri-hull cuddy.
In doing some research, I find some economical 4cyl rebuilt long blocks but
no 6 cyl. Would a 4cyl 2.5L have enough HP to make a reasonable replacement?
I was just given a 1968 T-bird tri-hull with Mercruiser I/O featuring a GMC
160 straight six. Has not been run in about 10 years plus stored outside.
Would this possibly be worth fixing?[/ATTACH]
