I didn't think there was a dual plane M1 for the MPI. The only version I've seen is a dual plane M1 for carburetor. Or are you talking about modifying the carburated one by drilling holes and welding bungs on for the injectors?Neil F. said:The single plane M1 is the same height as the stock intake.
There are not really many alternatives. Huges engines offers ported stockers with modifed runners. There are not a lot of people who have gone that route. It is touted to keep the low end HP and torque. The single plane M1 is more of a racing intake with shorter runners so it makes more HP in the higher rpms. Some feel low end torque loss with the M1 alone. The dual plane M1 has even shorter runners and is better suited for motors making 400+ HP. The dual plane also requires minor modifications to install it.
You list a custom intake. What is it?
I don't know how much they are currently going for. I believe 350+ plus the install kit which is an additional 50 or so.

Some of the smog laws I just don't under stand. I ran my 69 on the smog machine one time with my other motor in it just to see what the difference in readings would be and it ran a lot cleaner then the smog legal one.Neil F. said:Sometimes? That kind of crap every two years would make me hate it year round. Who cares what is under the hood, as long as what comes out meets standards. That's the way NJ handles it.
