Very interesting video and results, thanks for passing that along! His stock 4bbl dyno numbers are bang on with GM's published results for a 350 with a 4bbl of that year, 275hp & 350lbs of torque. I haven't made a decision yet but just keeping it stock and adding the 4bbl might be the way I go as I'm not looking for crazy power..

On the other hand, a good set of heads and a little cam could bring me above 300hp reliably and closer to 400lbs of torque!!
