    Lightbulb Looking for a new manifold/carb combo?

    I currently have a BBC (396") that currently has a Street Demon 750 cfm on top of a Edelbrock Torker 2 single-plane manifold. I got the Torker 2 primarily to avoid hood clearance issues. Car is only a cruiser for street use only. The engine runs fine and I have no problem with the current carb & manifold setup. However, I have been debating whether to go to a dual-plane manifold. I don't really want to ditch the Street Demon carb, but the design of the secondary goggle valve (may) interferes with the plenum unless it's milled down. I don't want to run a spacer, because of potential hood clearance issues ('69 Chevelle). So what I'm asking for, is dual plane manifold recommendations that will work with the Street Demon (1904) setup. The other option is a new 750 cfm carb and dual-plane manifold. Note: Thanks in advance. Cheers, Jim

    Dyno comparison between Edelbrock single-plane & dual-plane intake manifolds. You may want to mill down the center plenum divider anyway. Watch this video (especially from 5:05 minutes):

    May God's grace bless you in the Lord Jesus Christ.

    Good stuff. I figured as much. Just trying to keep the same carb and not spend the extra $$.
