What are your intentions with this thing- street/strip or drag only? pump gas or race gas? Either way I wouldn't be using that cast crank - how many times do you want to build it? The large plenum M1 is not the hot ticket for 360 cubes and as mentioned a 950 would be a better choice. If your wanting max power there can only be 1 choice- solid roller- how high do you want to spin it?
- how many times do you want to build it?
