360 build. Is this good street build? Heads work?

If you already have this bolted together then run it. It will be fun on the street. If not you may look at a different cam to get a little more out of it.

What kind of adapter are you using on the air gap to run the thermoquad?
Just an 3/4" spreadbore to squarebore spacer. I don't remember if I have another spacer in there or not. I brought one to the dyno but I wasn't there when it ran and don't think it was used.
