I personally would return the throttle body and use that $250 on something else since it is an expensive paperweight. The only thing you will gain is a marginal increase in throttle response unless you are extremely modified (600whp+)
Wow, if ours is 63mm I think someone changed mine out lol, there is no way there was only 2mm difference between the two tb's

BV heads, P&P lower, windstar upper, comp 218/226, 4.2 bottom end, 3k stall, flow 40's, O/R x-pipe, Pacesetter lt's, Xcal2, 65mm tb, CAI, 8.8 w/ 3.73's, MM LCA's
