Has anyone took a 77 block and had it sleeved to 4 inch and had the crank underground to 4inch? I already have the crank done and I have the sleeves for the 4 inch bore. I was just wondering if you could get 70+ horsepower from this moter. It will run 2100 rpm"s and the cam is set up for that rpm, also the head has been ported and and bigger valves. Running the new intake manifold from Murphey"s and a 1650 carb. Should I run the roller rockers or just keep the stock ones? Thanks for you help.
