410'

thanks for the advice crazy 340. at this point i just want to get the engine up and running. i mean im willing to spend the 1000 bucks to get the heads worked on and use them for this spring summer and fall and than next winter id love to get a set of w2 econo's. why was the m1 single plane a bad choice??? would you rather go with a dual plane like the performer rpm or airgap??? and the highest stall im really willing to go will be about 3500 as my car is street driven 95 percent of the time. i dont know what your w2's flow but is your cam really to big? or is the ideal operating rpm for that cam just to high for the 4 inch arm?
