Small block + 4 speed build

in this case a wider LSA is possibly the better solution. Less "peaky" torque production. I also would prefer the TrickFlow single plane intake over the air gap.....especially with the rpm band you expect.

Regarding the pistons: i run hypereutectic KB356 with good results, but strictly no power adder - and with the plans of using nitrous i´d absolutely suggest going forged.

Regarding the HR cam with SR lifters we have to talk separately....i´ll go this route for next season.
