Hi Rusty - I know you want something close but offering this for consideration..........
I purchased a 1940 Coupe from an estate sale. The deceased was restoring the car. I have 1-1/2 248 straight eights with two bellhousings, clutches and flywheels
Also a three speed manual transmission.
I put one motor together loosely, the bore is standard size, the head has been gone through with all new exhaust valves.
All parts are there to finish and includes duplicate manifolds (no cracks), carb and other parts
Unfortunately I am in Madison, Wisconsin...........
If You are interested or
