M1 Sb intake. Best for small blocks?

Make sure that you use a manifold with the smaller 273/318 ports unless you are going to gasket match the manifold to the ports (lot of work for a 318 IMHO). Best small port manifold for a 318 streets car? Edelbrock LD-4B. Cheapest good manifold? a used Edelbrock Performer

LD-48 Looks pretty cool! But yeah, they have a high price tag. Be nice to happen upon a deal for one of those! So sounds like I'm better off with the LD48 or the performer. And I should just pass on the M1 dual plane intake for this engine. I appreciate all the help guys! Going to be looking at my timing, stall converter and gears next. Seems like a project is never done! ( Course that's what makes it fun!!):thumbsup:
