Why not build a 340?

Thanks for the info. The 340 is being hot tanked and prepped. Harder to find a 360 than a 340 at a reasonable cost? I would of never imagined it would turn out this way.

The Performer dual plane manifold I bought is a spread bore. At some point I'd like to try a Thermo quad on it. I had a 780 on a 327 and it worked better than anything else I had used on it. Everybody (mostly) says it's too much carb, I found it worked great, the most problem free carb up to that point. Keeping in mind, that was back in the day of problematic Holley carbs, power valve issues using the 600. God those were a pain in the ***!
