On a 5.0 (87-93) the stock TB is 60mm and an upgrade is recomended to a 65mm. The 65mm is said to work well up to 500hp or so.
My question..is it worth it to go up to a 70mm or will 65mm be cool? Will 70mm be overkill? I know our engine is not a 5.0 but I have to ask.
Luckily we have 2 people that just did both
