As provamo said earlier, get out and race it. The suspension, carb, and intake aren't deal breakers; just changes made over time. Performance is something you can worry about when you get seat time. Most people would probably just like to see the roll bar fixed up first.
Your friendly SCCA Solo/AutoX people could likely refer you to a few people familiar with Vees in your area, and I think almost any racer would lend a hand to get it safe for you. You may need to add a currently dated safety harness, as I don't see one in the pictures previously posted.
The VSCDA operates in your area, and they have a race at Blackhawk Farms Raceway this weekend, that's about 5 hours northwest of Indianapolis. They may be a good resource for you to find another vintage Vee owner near you that can offer some on-site advice as well. Whether you go to the race or not, I'm sure there are vintage Vees near you.

Vees won't drive a large $$ on the market when completely restored, compared to other open wheel marques/classes. But that's because they're also not terribly expensive cars to race and maintain, compared to other things. I'd love to pay Vee prices for my British stuff...
