Carlo!
Nice looking flatty!
I hope you have better luck with those Ball&Ball carbs than I have. I finally have mine straightened out.
One thing, You may want to notice the discussion of "long" vs. "short" engines in this thread. The spitfire engines that I've seen are the "long" versions of 250 cid. The trick head to have on the short engines is the '58 heads from HD series engines. However, the earlier ones may have value in the modifications Del and I have mentioned previously. By the way, the top hp listed for the 230 was 125hp in '58 which is the base engine we're using in the tractor.
As I've said before, the only real modifications to our engine, beyond blueprinting to exact dimentions, is the crank/rod work, a dual offy manifold with B&B carbs, and a regrind on the camshaft. We just wanted to see what we could do with the "basic" engine first - then get funky with it.
So far, its doing pretty good just like it is - but I want the next phase in the hopper and ready to go too.
Thanks for your link!
