Block off plates...
Block off plates...
I searched using the p/n on shoeboxes site and apparently the LT4 block off plate was either discontinued or p/n changed. Where can I find one?
Also, I haven't been able to find a block off plate for the EGR pipe entry into my LT's.
Thanks

I also have to get some block off plates. Is SJM-1001 the correct part number if you're installing race headers and removing the AIR and EGR systems? I think I would only need to block the two ports on the rear of the intake.
The SJM parts are for the EGR system.... the 3-piece set includes one for the connection on the exhaust manifold or header (#8) for the flex pipe, one for the connection on the intake manifold for the flex pipe, and one for the hole the EGR valve goes in. Except for the 93's, EGR has nothing to do with AIR.
AIR typically requires threaded plugs (metric) if you have connections on the exhaust manifolds or headers, and a vacuum cap for the connection on the intake air ducting.

Thanks for the clarification on that. I'll need block off plates and vacuum caps. I'm going with non-emissions headers and offroad y-pipe. I hope I don't end up regretting that.
We have everything you need to remove the EGR and AIR systems from your car:
