318/360 heads,with thumper cam

No the m1 is a single plain intake,90 or best offer,is that not a good choice,if not a can try n find an air gap,or an rpm at this months mopar show,thanks for all the help so far.

I think with your cubes and rear gear the single plane is gonna be way too weak at low rpm's. Not saying it's not worth buying at that price for a future project, but i wouldn't use it here. If you can pick up either Eddy, regular RPM or airgap, used for a deal that's what i'd do.
