Exactly same here, lazy 66 built 428 on my gal !

It accelerates ok from 30 mhp to 70 mph,

0-60mph very slowly , max rpm ca 2500-2800 rpm,
when secondary vacuum venruris open , sboooooooo sound and nothin happends.

At normal traffic, typical zero to 40 mph, goes easy, rpm 0-1600 rpm.

Very drivable, but no way burn rubber.
