EGR plate delete on a 1979 7.5l 460
 
[B[Hello all, the old holley 4 barrel 1850 carb needed a rebuild so while pulling it off I noticed that the EGR was a plate sandwiched between the carb base and the intake manifold base.
My question is can I remove the EGR and the plate put carb spacer in its place? Currently the EGR isnt hooked to anything.
What do you think or has anyone had had any experience doing this?

You can get an adaptor that will replace the EGR plate. I put the transdapt 2199 on mine. It is a complete kit so you wouldn’t need anything else. They are getting expensive though. They are currently running about $65.00

Thanks Gary. I ended up just sticking it back on unhooked up of course.

i could get an older non-egr gasket set and fill the egr hole with jbweld. Off the engine of course. Any body ever tried that?

Thatís an interesting concept. I have over the years used JB weld to patch up all kinds of things all the way from cracked blocks to cracked motorcycle cases. I have even raced motorcycles across the desert that was patched back together with JB Weld. But you still have one problem; a square bore carburetors secondaries will not open on that manifold unless you do some grinding on those secondary holes. I am not sure how the JB Weld will hold up with all that expanding and contracting that the hot exhaust gases is going to make the manifold go through. That exhaust really heats up that EGR hole. Another advantage of the adaptor plate is keeping the carburetor cooler. I added the Edelbrock wood fiber spacer on top of the adaptor plate and it completely stopped the carburetor percolating the gas when the engine is run under hot conditions.

Hi Gary, Thanks for your input. I tried looking for the adapter looks like a carb spacer but has a ear on the side between the primaries and secondary at the mating surface.
Could never find one that completely covered that ear area.
I think after the points that you have made i will go ahead with the pre72 gasket and froget the JBWELD.
Thanks again for your input, Jon

Doesn't your 79 have a square bore intake and the Ford/holley square bore 4-barrel ?

bullnose1985 08-15-2015 04:18 PM

Hello redroad, yes it dose however its betqeen the primary and secondary on the passenger side a spacer only covers part of the egr hole.

My mistake, I didn’t pay attention to his post. The 79 was a square bore. 78 back had the mickey mouse large secondaries. I hope I didn’t throw you off.
