If you use small filters to cut down on the air going in you can really restrict the velocity (especially with a big volume tunnel ram that won't see much velocity in the first place) which will make the motor run crappy even if it did have a lot of better components and ran higher rpm. The carbs would be hell to tune in that situation as well. If you had a cam that ran from 3500-7000 rpm with those big carbs and tunnel ram, and other components that can stand those consistent rpms obviously then I imagine they could work...but in that case you wouldn't be using the smaller filters anyhow. Think of an engine as an air pump with a certain volume of air capacity. Due to intake and exhaust design, pumping losses and friction and whatnot this air pump usually never ever sees 100 percent volumetric efficiency unless it has a blower or turbo. SO, even if you ran 8000 rpm with a 360 *way overbored 350* and 90 percent efficiency, which is really really good for a naturally aspirated motor, you would only be e to pump 750 cfm through that motor anyway. You would have to run 9600 rpm with a 360 at 90 percent efficiency to get 900 cfm flowing. My suggestion, stroke the damn thing and make a 383, keep the intake, get some 1 5/8 or 1 3/4 headers, big cam, some lightweight but strong (bigger skirt too) pistons (if thats possible) or normal weight and buy some forged rods. Depending on the rpm and power a cast crank may be fine, but if you got money then go out and get a forged (why not, right??). Stud the mains and heads, get some aftermarket heads like Dart, AFR, Victor Jr, or your personal preference. Make sure you have some good ignition for those high rpm blasts. I am pretty sure you know most of this but I figured I would let my opinion out.
and he still wont be able to drive it to the store for a 6 pack. :CRY:
