Use an s475 works just fine. I’ve done it myself w a dead stock 350 ran 11 flat at 10 psi. Worked great on the street. 70 350 2bbl motor out of a lemans. Raced it for a full season that way. Ran good yanked it out and put it in a 67 bird n/a ran well for another 6 years before I lost track of the car.
