opinions welcome on build.

Why in the world would I put a year's wages into a street brawler and then idle it thru a park at 1400. I couldn't gibachit if anybody notices me. In fact I hope they don't.
No I'm driving thechit outta mine as much as I can for as long as I can, to get my money's worth of fun out of it. During the first five years I even drove it non-stop thru every winter, stuffing a 318 into it and testing different transmissions and gear combos. I drive my heap. If/when it breaks, I fix it and drive it harder until something else breaks.
While the 367 was out every winter, I freshened it up, and modified the guts to make it more reliable, so I could drive thechit out of it harder again, next summer. I'm getting my money's worth.
And all the while you were doing what on the street? oh I remember; idling thru the park at 1400. Yeah that's helping OP. Get a merry-go-round
And your approach doesn't make much sense to me. You spend all that effort building a nice performance car and never take it to the track. My assumption is that the OP may want some time slips , not just tire spin on the street.
