Cheaper way is a rubber expansion plug from lowe's/home depot. 1 3/8" IIRC

Manifold plugs are easily made by cutting the tube off and welding the hole shut in the stock plate. I ground mine flush afterwards and they look like aftermarket block offs

Any auto parts store has 1 3/8 rubber expanding freeze plugs for around $2 vs $20 for the GM plug. Worked great in my 99 LS1. (Thanks again to this forum for the money saving tip!)

I have the gm block off, it came with my intake manifold. I really don't like the look of the freeze plugs or the gm part. It looks unfinished.

I thought about using the gm part and putting a billet cover on top of that. Has anyone done this? Seems like a 1/8 or 1/4 plate would work.

It would be cool to do something like that and have the engine size (5.3) engraved in the top of it.

Street & Performance does basically the same thing with their billet block-off plates, they are available with a few different engravings, but like most other S&P parts, they are high $$$.

Yeah I'm kind of anti-S&P because of thier high pricing, sad because I can actually drive to thier place.

You think with all that money they make they can pay someone to update thier website to be easier to navigate and do away with all the pdf links. Plus having an actual website with online shopping and check-out feature would pay off in the long run.

I may get a raw piece of aluminum and play with it. Thanks again

I agree with you on both of those statements!
