Holy crap!

Impressive deal for sure. That thing sounds sooo good all wound up! I've always wondered what a stock stroke 400 could do with a big roller, VERY good heads, and induction. What were the Pro Stock cars pushing for power in the early 90s? This reminds me a lot of those.
It kinda does put Pro Stock in mind, doesn't it? ....and those had a 500 cube limit, right? I think that's right.
