440 power gains/ aluminum head advantages?
Getting my 440 swapped 74 dart dialed in good finally thanks to help on here and lots of tuning. it rides good and runs great. but i'm a bit disappointed by how much power it has. it's a mild build but i expected more out of it and wanted to know what you guys would do to get more out of it. it's a strip car that i drive on the weekends. stock stroke 440 with cast open chamber heads, 2355f pistons, stock rods and cast crank, .505 hydraulic flat tappet lift cam with 108 lobe sep and 280ish advertised duration. and an 800cfm holley. with the 3500 stall converter, fmvb, 4:56 gears and caltracs with 10.5in slicks it'll spin if you punch it from a dead stop on the street but if you mash the pedal cruising in any gear it doesn't pull like i'd expect. and i've got it tuned pretty good with my setup. would going closed chamber aluminum heads be a good place to start? idk if the better compression and flow advantages would be noticeable with my setup. at some point i'd like to go roller valvetrain with a better cam. any other places you guys would see as a bottle neck for torque? i'm sure i left some stuff out so any advice or questions would be appreciated!
