Hey guys, I have an 84 Monte Carlo SS with the factory 305 HO engine.
I also have a set of ported aluminum Corvette heads that I would like to install on this motor along with a set of emission legal Hooker headers I bought.
What are my options to keep the EGR wit the heads on a carbed intake?
AS a last resort if I just install the EGR on the intake as normal with these heads even though it wont funuction or I just block the EGR mounting plate will this cause any codes or check engine lights?
Thanks guys

 

Why are you keeping the EGR? It will decrease power and fuel economy, but if you have to have it, the system should run through the intake and exhaust manifolds alone, I don't recall having any air ports on the head. You will still pull a code if the O2 mixture is not right for the picky '80s computers though, just be aware.

 

EGR doesn't reduce power or fuel economy. I don't know about the '84 G-body HO, but not having EGR functioning can trip the knock sensor, which pulls timing, which reduces power and economy. So, depending upon the tune, not having EGR functioning can hurt you.

The computer looks for a load on the EGR solenoid circuit. So, at a minimum, keep the EGR solenoid hooked up electrically.

I haven't verified this, but have been told the ECM looks for a vacuum drop coincident with commanding the EGR open. I haven't checked for trouble codes lately, but apparently a code can be set for this without turning on the SES light.

The old "350 HO Camaro Conversion Kit" originally came with a tube that connected the exhaust to the intake manifold via the hot air choke boss. The factory manifolds don't have the hot air choke boss, but the ZZ4 (GMPP q-jet EGR intake) did. The later versions of that kit deleted EGR from the kit and PROM, however. So, hooking up EGR really depends upon what intake you'll be using.

 

five7kid, I had planned on reinstalling the EGR on the intake when I change the heads, I just did not know if I would run into issues with the SES light and was also worried about the knock sensor pulling timing.
I already have the heads and they have very few miles since they were ported and they flow pretty well so I thought I would put them on when installing my Hooker emission legal headers and Y-pipe. I just dont wont to run into problems by using them since they do not have the EGR ports.
I am familiar with the Vette set up but how would you connect a set up similar to that on a carbed intake with only 1 EGR connection point?
Thanks for any and all help and sugestions.
