Subject: 72mm TB to big for 4.7?|

The truck feels about the same when I reinstall my 65 Ported TB.

get an air fuel guage. they are accurate at 14.7 to one. and so so above and below that. it should give you a rough idea if your feeling is right about running rich. remove any resistors or jet chips you have on the iat sensor. .02
