Factory hydraulic roller LA cam advice
considering it's just a stoplight eliminator, i figure that you'd be looking at something that's not gonna get full wrung out all the time. so keeping the "small" performer and those 308's might be just fine and dandy.
i'd go with more gear out back for sure.
personally, i'd probably err toward a little more conservative on the cam. XS268S10
but if you were changing the manifold and carb i'd probably say the howards 710525-10 would be a pretty stout piece. i think you have the compression and stall for it, but you would definitely want something like 3.91's out back.
just my 02
