I have a 87 speed density 5.0 with full exhaust and a FRPP 65mm Throttle Body. If I wanted to convert to mass air. Could I use a stock system from a boneyard or use FRPP conversion kit, or forget it since I don't need it.
Yeah the pony lost some horses, but go and try putting a cam in your speed density car and see why its worth it. I would think after reading your other post on all of the other things that you have, it would be time for a slightly larger one, because im sure you will definetly need one in the future anyway with the way your modding.
Will the stock MAF work with a FRPP 65mm T/B....sure. Will it give you any additional power...not likely. Is it a bottle neck....no more than before. Is the conversion worth it without doing a cam, intake and head swap. Nope!
