This project has been awhile in the doing. It has ended up requiring the use of a lot of different tools. Here I am starting the taping of the water outlet holes. I was struggling with how to drill the holes nice and squarely into the end of the head and then realized that my Shop Smith was just right. I started with a Joe Bell casting
Left to fabricate is the intake and exhaust systems. I am well begun on both those items.
With luck I will be ready for the Lincoln Nebraska event!!!!
Looking good. Ive only seen 1 head that was built from scratch using a couple blocks of aluminum (a staggered 8V overhead with offset push rods).
Nice! Can't wait to hear how it runs.
Thx guys. The combustion chamber and pistons copy the 37-53 flathead V8. The cam is a special that Bill Stipe and I came up with
Well Les, I think you are the only one that has done any thing with the raw castings, I sold two others casting like your and have never heard of them finishing them. Any one that has machined a raw casting finds out they are more setups and machining than most people want to pay for. That is why I only made a dozen of them!
Well you made my day!!! Not that I wish anyone else misfortune. It's a heck of a lot of "putting one foot in front of the other ". And a certain amount of one step ahead and two steps back some days
Les have you measured it for how many CC's that chamber is? Looks like it'll make a ton of compression. Also, how much valve lift will it handle? I can't really tell in the photo, but it doesn't look like it ramps very steeply from the cylinder squish area to the valve area. I like it.
I like seeing the real creative old skills like this. Nice work.
I haven't done any volume measurements. Lots of actual measurements so that I am pretty confident that I will have about.040-.050 piston and valve to head clearance. The close valve clearance was why I made the spark plug "pockets. One of those compromises to get maximum compression ratio!!
At assembly I will verify clearance using "plasticine "
