8ba crank in a 36 LB block
I know its been done but I was just wondering the particulars on the machining especially for the rear main seal and what else has to be done with the main journals besides making them smaller to fit the smaller line bore in the 36... I hear that ol Ron has done this so hopefully he will chime in

Re: 8ba crank in a 36 LB block
I looked at fitting a later crank into a LB block,main reasons for thinking of this was I had a pile of standard flanged rod bearings ,so thought I could machine the rod journals down to 1.999, But it got to be more than that,mains were wider or narrower I can't remember,different dia too.
We are not the first to think of this,and I,m sure someone has done it. Lawrie |

I'm not sure if the power increase of adding a 4" merc crank would be worth the investment of the machine work but it would be a fun project. Why stop there.....wet sleeve for 3-3/16" bore? |
