Bolt-on mods??




Picking up my "new" 92' this weekend. All maintenance up to date, great condition, new tranny, etc.
Besides the obvious mods of free flow exhaust & air filter, what bolt-on mods has everyone seen that gives most "bang for buck"?
Budget will be limited so will do mods "bit by bit" over time.
I know opionions vary on this but would love to see what has worked best for you all. My first LT-1 w/ my experience from "many a year ago" being 5.0 Fords in my youth.
Thanks!

I assume you're including long-tube headers in your definition of "free-flowing exhaust". If not, they're usually worth ~15hp.
1.6 roller rockers are generally good for 10-15hp.
An electric water pump is good for 6-8hp.
There are a bunch of little "free mods" that pick up a few hp here and there.
Weight reduction always works, of course.
Go much beyond that, and you're looking at some pretty decent coin for a H/C package, stroker, FI, etc.
Congrats on the "new" C4!
