The cross ram intakes just aren't that good when it is all said an done. If this is just a cruiser and you like the looks of the cross ram then put a pair of Edelbrock 500's on there. At least those carbs will allow you to start the engine without too much drama and you'll get half way decent performance. At the minimum you should install a dual channel wideband. Good luck actually trying to tune that thing though. You'll get lost really quickly if you try to cross jet it or popsicle stick the intake or anything else. There is a reason they don't make those intake manifolds anymore!
