Speed density is really the only way to go with a cam that size. Its not even worth running around with a MAF.
One thing I would do is run stock rockers. Aftermarket rockers are going to be heavy on the valve train and you will wind up lossing power on the top as well. Found this out with the rockers we have on our 429. It makes good torque, but the power falls off before we can get up to the top. So now we are putting the stock rockers back on and lowering the lift some.

I only say this because some engines have a problem with heavy valve train and thats why power falls off. If yours makes power, then more power to you and you are doing great. As for MAF or no MAF, you may think its nice now, but try it no MAF.
