EGR for duraspark

[kimcrwbr1]

I have been trying to get the EGR on my 2.8 working after the duraspark conversion. I think I have it figured out I bought a universal EGR tomco 10427 with two ports one is connected to ported vacuum on the carb and the other I connected to a vacuum restrictor that is vented to the air horn on the carb bringing in filtered air. The way it is working is it lowers the vacuum to the egr to about 4hg max with manifold vac at 20hg rpm around 3000. The EGR comes with a variety of washers I am using the second smallest one I cant remember the size. Anyway the engine seems alot peppier and I am hopeing for better gas mileage.

I figured since my 2.8 is giving me 10mpg, Ill just drop a 5.0 in her, still get 10mpg (or maybe better) and have that much more engine to get me around.

My truck does great but wont go over 60 mph easily and regearing will cost more then I will want to. With my 5.0, gearing I have should do the trick plus I plan on upgrading the rear end anyways, would do that for regearing anyways.

But for guys wanting to keep their 2.8, keep finding out what it takes to get the most out of them.

One of the best things I saw guys get out of them was to make them TBI. I did it but didnt have the time to fine tune it, let alone tune it much, and was getting like 8mpg. But knowing now about the TBI swap and using a 2.9 harness would have helped alot. Guys have reported getting 20mpg with TBI.

Right now my 2.8 is getting 16 mixed and hopeing for 18 or better with a new torque converter.
