72 340 engine

My 340 has 198-205/cyl compression test ,on a 1970 340 10:5.1 pistons lunati 60403 cam air gap intake . The was not a huge difference when I switched intake from stock .The 1970 intake is dual plane , even bore , 1971 0r 1972 went spread bore I think . The Carter is a good carb
You should get between 300 and 400 HP depending on cam pistons and if the heads were worked on
