is this a good deal?

I have a built-up 340 and a slant six. The 340 has always seemed fast enough already, whereas the slant has been fun to play with and try to get to go faster. After planing the head, porting and radius work, the engine has really perked up. I have an overdrive, and am gearing the differential down a little for quickness. It depends what you're looking for, but I think you'd enjoy messing around with the 6. I had an extra cylinder head in case I screwed the original one up, but didn't need it. Also, the 6 is in a ragtop, so I didn't want to drive too insanely in the first place. It's been a good learning experience.
