    I found one at a hill climb but it will not post. It has a mpg at the end of it.

        I was lucky I grew up in a family that had a cement block and gravel business. My Dad and uncles made a lot of there things that they needed. Built there own houses, built the cement block factory building, built there own gravel bins, built a barge with a big gravel pump inside to pump sand and gravel from the pond. Repaired there own trucks. plus much more. So I grew up not knowing that I could not do it. My wise Dad said there is nothing in life you can not do, but there maybe a lot of things you won't do.

              HOLY SMOKES!!

              Do you know how hard it is to burn any rubber with any Model A?

              He not only has to take it easy at the start to not burn the tires off, he chirps in second and third gear!!

              What a drive, THANKS for sharing. I have a whole new respect for the machine work done on that head.

              George, did you even check to see what kind of horsepower you are getting to the tires? Even a guesstimate?

              What transmission you running behind that beast?

                No I have no clue. But I had to put bolts in to the frame to jack the weight on the right rear and left front to keep from spinning the tires real bad. It was fun to drive. I'm thinking over a 100 hp at the engine. One thing you have to have is a radius in the corners of the rod journals and mains or you will be braking a crank shaft. No one wanted to put radius on there grinding wheel so I ground the crank in my lath, with a portable crank grinder from my Dads garage.

                  Ok, need to know, what was the distance traveled, and what kind of time?

                  Short distance, I would bet 4:11 rear ratio with stock size tires.

                    I was running a 39 Ford transmission ,but about that time I changed to a F 150 four speed with 4 gear being over drive. I think that it had the 39 ford then, but not sure. It was one of the two.

                      It has a stock 3:78 I will look up figures.
                      I'm still looking for my time slips, but my guise is 10 tenth of a mile, speed around 60, time some where in the 9 seconds range. There was maybe 10 percent grade.

                            this is how I ground the crankshaft. In my lath with my Dads old probable crank grinder.

                              This is what happens if you do not use a radius on a high hp model A engine.

                                  I remember Andy Blackburn coming over to my garage with his portable crankshaft grinder and turning the throw on my 53 Studebaker that I managed to destroy as a teenager, back in 1960. It held up fine, but when I think back to the dirty conditions we worked in those days, I'm amazed.

                                  George, you are a man above us all with your skills and the things you manage to pull off. Sure wish I lived closer and could just go hang around while you work, bet I could learn sooo much.

                                  Question: when selecting a head to adapt to the model A block (as in the case of the Olds), did you consider any other with a closer match on bore spacing, or is there just nothing that matches up better? I'm thinking maybe a 6 cylinder head or something might line up better.

                                  Also, on the head you filled from scratch, why did you choose to not do a hemi design? Seems like that would get you bigger valves and better flow... Just curious...

                                    Well the truth is I found the olds head at work in the dumpster. I looked at it and said, that is real close to the model A block.
                                    I'm not that fond of the hemi
                                    The Model A has more space between 2 and 3 because the dist has to go there. So no head that I know of would work. with out work to make it fit.

                                          Tom W in particular will be interested in this.

                                          The debate, at least in the Model A world, will rage on in perpetuity, despite that the Service Bulletins state to re-torque hot.
