Throttle Body Upgrade?

Is there any throttle body upgrades for an 87' 4.0inline cherokee?:dunno:

1. If your talking other wise bone stock 4.0? With no plans of other engine mods'
2. Buy upgrade are you talking about a mod that will show some kind of real performance improvement?
Then IMO no.
How put a late model intake manafold under that oversized TB and a new poop pipe with a bigger hole in the end and you MAY see some REAL HP gain. Cams are nice to.

PS: The oversize TB still don't count for much but bragging rights.

A good bud is hard to find!
Even harder to lose.
Work safe.

well i planned on a bigger tb and a 95 ho exhaust manifold, bigger injectors and a snorkel and possibly a msd ignition.
