[6T7 C10]

I am running a new crate L31 that I installed this past winter. My setup includes the GMPP serpentine belt kit GM12497697, Summit Stage 1 intake manifold 226018, Edelbrock 500cfm carb 1802, Fel-Pro head gaskets 1094, Comp 1.52 rocker arms 1617, Summit HEI distributor 850001R, ram's horn manifolds, and dip stick tube GM12551154. The rest is stock. I have and electric fuel pump SP1130 and electric cooling fans. My dash has the warning lights and I found that a Standard TS81 switch is 240* and fits the head for the water temperature. It is probably running right under or about 300 HP as it is and has strong low-mid range. Hope this helps.
