Better cam and an 1 3/4 primary header will work wonders.

Yep, thats the plan.  I am going to start with a cam, cuz new quality headers cost wayy too much for my pay grade.

x10 Rich =D.

Sounds like you've got a good little setup going...it just needs some sprucing up in a few places is all!

For the headers...take a look around the Corral classifieds.  Often you can pick up decent fox body (assuming there) big tube headers for $300 +/-.  I think that will make a HUGE difference, and set you up for all of the benefits of a good custom cam.

Plus, exhaust is the easier swap =D.

Definitely keep us posted on how it goes.  I'd like to see how it runs once the changes are made.

Ditto, it has a lot holding it back above the current power peak. It should go much higher with that torque peak rpm point.

This is a before dyno.  I changed from Performer 6037s and an RPM intake to the AFRs, Vic, and bigger TB, MAF.  Just for fun, here it is.  Amazing what air flow does Hmmmmm

What's wrong with that chart, one or the other curve is off. The curves of power and torque always cross at 5250 rpm. One of those curves does not match the rpm scale, and needs to move to cross the other at 5250 rpm.

The values of HP and TQ on the sides are different

Ah, they mixed up the values along the sides, that makes the comparisons less valuable. The side numbers should also match, like the normal dyno sheet farther above that.

The normal curves using both parameters matching gives you a good idea of how the curves are, versus how they should be. The power peak should be near 50% higher than the torque peak. Meaning that a 4000rpm torque peak should point to a power curve that goes past 6000rpm usefully.

A guy said his 1 3/4 Mac headers were hurting his low end, so I traded him straight across for my BBK 1 5/8

I know the ass dyno is not accurate, but the gain is VERY noticable, shortly we will see what the roller dyno says about it

Don't expect the roller dyno the whole story. Wink

OK, I added the 1 3/4 headers, installed a Tweecer, and slid in an XE274hr that I had on the shelf (which I noticed very little difference other than idle sound).  It is not the same dyno as my original pulls, so I guess I am taking the results with a grain of salt.  The wideband is screwed, he changed sensors on the next car after his curve looked as retarded as mine.
