Im not sure about that combination. The heads you have could support 400 hp.I dont like the cam.That intake is what I use on a 434 solid roller motor. carb is fine.
If you want to rum high 12s,you need a car that hooks well with proper gear set/transmission. weighing only 2500 pounds makes the task a lot easier. Is the car set up now? is the 355 in it now? weigh it,make a pass,get the mph and actual weight and decide if you need more power or just want bigger numbers?
