Below, the first 7 pictures are of a modified LD-340 with the center divider milled dwon as per the DC/MP booksrecomendations. The sides of the carb flange were filled in for a better sealing surface. You can still see where the divider was making this a dual plane intake. This mod worked well with, higher rpm camshafts and the like mods needed with them. Low end torque was improved over the single plane intakes but not by a margin work talking about since that rpm area is largely ignored by the bigger camshaft.
It was a neat trick. Looks like a dual plane, explodes in power up top.
Below is a "Down the throat" biz end of a M1 single and an Indy intake. All the cylinders feed into a common plenum with as straight as possible runners. I posted these two intakes to show the carb pad, air entry design differences. The Indy (Bottom) is very tall, with a square carb entry for as close to an equal runner length, shared plenum area, as close as possible balanced air and fuel intake charge with a smoother entry from the carb.
The MP - M1 has the spreadbore carb opening for use with the TQ. While the intake has been used for decades with much success, to use with a Holley carb requires the use of plenum floor dams and/or a modified recontoured, welded up intake pad. A worthy modification alebit expensive to the point of it would be better to get another intake. (But thats up to you.)
now also pay attention to how the carb pad enters the plenum. Note the sharp turns into the runners. Not the best. Compare to the Indy intake below with the more gentle and smoother radius turn into the runner.
A pair of single plane W2 intakes.
