i dont have desk top dyno i have a real dyno.you should make around 400hp the heads and cam are holding you back a little.it's a good combo if you were to go up a little on cam it would help the bb breath.soming like 530-550lift and 234 -240 at .050.leave lobe separation 110-112.it would pull good from the hole and give you a little more uptop.750 ok intake ok put a 1inch carb spacer and good ign.
