he told me to go with a 275deh, works with stock stall converter and relatively tall gear and the lift is 514/541, I looked around online and some people say the stock rocker shafts is questionable with over 540 lift (with) shorter pushrods, that might be why he didn't want me goin with to much lift but I see your point though ill make sure bring up the question with him, I'm kina excited but how do yall think this engine is gonna run? I'm pretty stoked about it, and thanks for all of your guys advice I learnt a few things I really appreciate it
