92+ Headers on Premag Engine
#11
#13
I've disabled it on several different vehicles, and I really didn't notice any difference in fuel consumption. But then, I have a neutronium foot anyway.....

Heh.
Different motor, different tuning.
But a friend of mine was carefully monitoring over some West Texas runs; EGR at max and 80MPH yielded a 20% improvement in gas mileage; from 20 to 24.
Shower down on the throttle, EGR will shut off (to enrich the mixture), and presto, no savings.
YMMV natch; and "one anecdote does not a data set make". But still, it's worth keeping for a highway car; worth disabling for a race car; make your own choice in between *grins*

I assume this question has been asked several times, but my Google search skills aren't up to the task. I have an 87 LA block. Premag headers (like the Edelbrock 68512/68513) are more or less non-existent. However, 92+ headers are rather available from many sources. The question is....will they fit? Are there any additional concerns?
I believe something like this will bolt to your engine. https://www.ebay.com/itm/FOR-92-02-R...9aBJQL&vxp=mtr
You could simply block off the egr mount on the header.
Then you could use this headpipe. https://www.ebay.com/itm/Walker-Exha...xaAnKz&vxp=mtr
You would need to extend the wiring for your o2 sensor.
But, the one concern I have is, will the headers clear the cab? It seems member Robertmee had a problem on a 90 truck he has. You may want to shoot him a pm and ask about it. https://dodgeforum.com/forum/members...robertmee.html
