Hesitation at 3000rpm

Thanks for the responce Guys. As I said there is no technical info available. I bought this blind to keep it in the family when my cousin passed. Is has a "727" withI think a 2500 stall. It didn't run till I put the distributor in it so I have no idea on the timming. To many questions that at this time I dont have or will never have the answers to. I really appreciate your help. It gives me a heads up on thins I have to figure out to eventually get it running good. Thank you all..
