I guess, in a sense, they might have as a result of more than one change
in specs. I understand that all '01 4.7's have precats(not all 00's
did). Also the new tb. Possibly more?, Don't know.
I guess the reason I'm asking is because I don't have a feel for the
difference in air flow(cfm or whatever) for a 3mm difference in tb
throat size. Doesn't seem like much.
FWIW, its only an interim step anyway as I've got my eye's on Bruce B's
billet tb along with matched injectors, etc. If nothing else it will
make cleaning stock tb's a little easier(install a clean one and take
your time soaking and cleaning another one)
Just curious.
