    Yes . Its the 7622. Very nice well cast manifold. Much lighter than the Edelbrock Vic Jr. with a better finish.

    I think you would be surprised see Lil Red 406 posts with his 555. near identical setup as you. get the suspension right and high 9's will not be a problem. My build is almost identical. Straub Solid Roller though and 315s dynode in the high 700s and had a 700 tq table over several thousand RPM. I'm right at 10:1 port matched intake. Jessel shaft rockers. Nothing crazy. Vortech Pro has built a lot of 496 that make 700 hp and have run deep in to the 9s at 3500 lbs.

    His set up does sound like mine ,should run good.

    I still have the 2 inch headman headers .I took a saw to them and cut the small 3 inch collector off and put bigger ones on.
