This morning I was photographing items needed for the CCAS submission. I thought some of you may find the suffix mark on the front of the right cylinder head interesting.....

Great car Tim! As always you're bring it to the next level

Very nice car Tim, congrats. I think it will take Al about 5 seconds to certify that pad. It's beautiful.

Thanks Steve!!

Here is one of the pics I sent Al.......

The 67 has aftermarket parts store exhaust on it. I knew that going in.

A friend of mine took an interest in the car, and hooked me up (for a sweet deal) a set of gently used GM Off Road mufflers and pipes (welded). I was then lucky enough to find a pair of the correct NOS sweged front pipes.

Some days you are just lucky!

Dad's 67 L79 had the welded GM off road system and there is hardly a sweeter sound than a factory hi-po small block exiting through that system (except maybe a solid lifter big block with factory side pipes.....)

Tim, that exhaust system will be perfect for that car. The only thing needed to make it look assembly line would be to remove the part #s from the mufflers but I am sure you know that. Great car.

I remember he would buzz that thing to 6 grand and the gurgle between shifts! What a sound!!:worship:

I did a workshop on removing the part numbers from an over the counter GM exhaust, we repeated this seminar at the 2023 Texas Regional.
The results were fantastic and this N11 system is on my 1967 L79 coupe.

Yesterday, I had a chance to install the NOS N11 exhaust system on the 67. I got the mufflers from a friend in New York. He's probably had them for about 20 years. While Gardner's does an impeccable job on their product, nothing seems to fit like NOS. As you can imagine, it kind of fell into the car if you will.

So I get everything finished up and go to light the candle. I'm thinking to myself.......this doesn't sound like N11 exhaust?? And then this started flying all over.

Looks like my buddy sent me a little more than the exhaust. Now it sounds like N11 should:)
