A beautiful combination of skill, knowledge and dedication to keeping a small part of the world "flat.".
 
Walt,

What size are the valves. Looks like they almost touch in the center.

Saw an 8BA block with valves like that Sunday when I bought some parts from another Barner. The guy said the motor came from a drag car and put out 475 HP. Had some super special crank with 4 7/16 " throw and had been bored to the max.
 
Walt, That is sure a great piece of workmanship. Outstanding craftsmanship by the true Flathead King.

D.Jones. Those are Chevy valves, same head dia. 1-1/2in as the Ford. They just look close in the pic. Walt
 
Walt,when was the last time you checked on that engine hanging from the bellhousing? Do you still check on them hourly? E.P.W>

OOOOOOOH no. I'm going to run out in the shop and check it. LOL If you go back a few weeks you'll find a long thread on this same subject. You can see that plate I made for the back of the block and the stand bolts to the plate. BUT, I've built 100's of flatheads and never used a plate until about 10yr's ago. Accually how many flatheads have you seen with broken bellhousings. I saw a pic of one once and if the trough be known, chances are the bolt weren't long enough or bolted up tight. I don't want to tell anybody how to mount there engine. Walt
 
Walt beautiful work. I'm curious how do you arrive at 276 Cu.In? I assume you use a 4" crank. What is the bore size? This is referring to an 8 BA block.

Thank you!

3-5/16 bore 4in. stroke. I haven't got the formula handy but I think it figures 274 something but for some reason 276 stick in my mind. I guess it's been said to many times. Call me a lier over 2ci LOL Walt
