Default Bolt-on mods??

Hi all:

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!

JKK

3.75 rear gears and a 2800 stahl makes a huge difference.

The LT1 responds well to gears, so the convertor/gears advice is sound.

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!
