Hello Gents,
The cranks for the Froggy Flatheads are either 3.75 or 4.00 stroke. I want the 3.75 version, to match up with my rods, which are 7". The "btc" site is the one that had first put some of my fears to rest prior to arranging to look at the block. Just over a week ago I knew absolutely nothing about these engines, now after searching and reading information everywhere, I still know almost nothing! Once I get the block back home, I will make an attachment to bolt onto one lf the exhaust stud sets, so I can rotate it 360 degrees while working on it. In no haste to assemble, and have a couple more books on order, to read before I try anything. Slowly, slowly, catchy monkey!
