Thanks for the opinions. I have heard both good and bad stories on the 670. Issues on older models had a few things, one being a lean stumble. Apparently the problem was with the primary metering block; Holley acknowledged the problem and has said to have fixed it on the new ones. Other than that I hear it is an easy carb to work on. It came with 3 secondary vacuum springs (Light, med, heavy)and a new quick change vac cover.

I'll play it by ear and may have to change the jets. As far as the bracket extension I may have to run down to the speed shop for that in the middle of the install this weekend.
