in a nut shell:
Sounds like you have a stout motor and for what you want to do with it is you might need to de-tune it some. Aside from the high CR, (what fuel are you running atm?) unknown cam and converter but knowing the gear you have, the weight of the car and how you want to run it, for intakes an RPM variant or dual plane of some sort would be a much better choice. Perspectives from street, street/strip, and pure race guys will vary. That M1 is a race piece, that can be made to work great on a street/strip setup but the whole package has to be really matched and complimentary. (Like anything)
