Briggs Flathead / New Flat-Head build...
« on: May 05, 2010, 09:41:46 pm »
Im going back to machinist school to finally get my degree and need a new project. Since I have sold all my pulling stuff I have decided to start collecting some odds and ends for this project since the motors seem to liter the world today.
Project Description: Building a Stroker / 10HP Using 11HP Crank.
Now, I know people are going to start bashing and stuff about my trying this. Saying that it can't be done. Thats fine, But I need a new project so I can do some stuff on the CAD machine.
Now, I have done some math in the process and here is what I came up with and why I have said it will work.
10HP Deck Height: 7.643
11HP Deck Height: 7.6499
In order to find Deck Height (Or Pop-Up)- Measure from TDC and add ***
1/2 Stroke+ Rod Length+ Compression Height+ ***= Deck Height
1.3125+ 4.8695+ 1.436+ .072= 7.69 Deck Height
7.643 (10HP DH)- 7.69 DH= .047 Pop-Up
So, This says to me, That I will have some pop-up but not enough to make a difference. This will allow me ample clearance for the factory head and the plug. One thing that I will have to check will be to see if the crank will clear the inside of the block of the 10HP. Sometimes the crank can hit the side and I may have to mill out a chunk and either weld in or replace with a cover.
I have some other ideas in my head that I am throwing around, but I'll post those up a little later after I get those down on paper.
