[quote=Quicksilver440][quote=lewtot184]a lot of good single carb info here, but i have to wonder if the manifold is best for the combo? it could be fine and i know it's had some good press but what "IF"? i don't care for single carb stuff much anymore, especially when cost is factored in. i'd open the door to a lot of options. the worst that looking could do is send you back to what you have.
We run ported 300-ish cfm heads and also run a Holley Street Dominator. Streetwize (Bobby) here on the board ported this SD and compared to an as-cast, it picked up a tenth on the dragstrip. Translated to about 12 hp as I recall. We also run an 850 Demon for a carb. For a heavy street car it runs pretty well and has great drivability.
