I am swapping a 4.9 out of a 93 Deville to a 88 Pontiac Fiero, and I read somewhere in this forum, that a Throttle Body Spacer will help a little bit on performance, and, I also need to raise the Air Hat a little bit, so why not a TB spacer.
I can not find any specific TB spacer for the Cadillac 4.9.
To what can I compare the Cadillac TB ?
What GM TB base is the same as the 4.9 ?
