You don't want to put a MW intake on 240 heads. That combination would make less power than a good std port intake.

For a budget engine use the Trick Flow intake with the 240 heads. If you have some spare money then send the TF intake to Hughes for their deep port match. If you have plenty of money then send the intake to Wilson or to someone else who knows how to port intakes.

The 4500 intake makes more power for all out racing but there aren't any really good std port 4500 intakes. The M1 is a decent intake but it needs to be ported before it is really good.

The TF intake with a big 4150 carb is probably the best solution for most people. If you already have a Dominator then try the M1 4500 out of the box. If you want to make a lot of power with 240 heads then buy my intake. I've already done the R&D and paid the money to Wilson. You can buy it from me for a lot less than what Wilson will charge you for the same work.
