there is some detailed math involved when choosing the right size carburetor for your engine. the equation looks like this. (CIDx max power rpm)/3456x volumetric efficiency=cfm.in your case you would need at least 507 cfm's to feed your engine.your best bet is to go with a 600 cfm carburetor and do your fine tuning with the jet sizes once the vehicle is running. The engine looks good, Id say go for it but keep in mind that its not a good idea to put a blower of any kind on that motor.
