Thanks James, that is great news, my car is a factory ac car too and I intend to keep it that way. I would love to find out who built that car and ask him a few questions (like did he use the taller bb motor mount frame bracket on the driver side). I'm assuming it had the SS hood?

Do your own homework.......but I believe '67 intakes are lower than the later years. Might get you where you need to be.
I believe 67 tri-power (L71) had higher intakes then in later 68/69 years. If someone needs I have a 69 Camaro with a original cross-ram with repro steel hood if measurements are needed. I remember 67 Camaro with L71's fitting under the hood and it was way COOL.

I've only ever owned the 69 version pictured above, the intake seemed to me to be pretty flat and I had previously read what Chick says, that the earlier versions were taller. I'd really be interested in seeing the bottom of that hood ( "original cross-ram with repro steel hood"   ) if it differs from original round hole ZL2 hoods.

jt did you ever get this installed? I finally think I have a 68 set up coming to try on my 69 Camaro with SS hood.

Gee, no Kelly. I haven't even gotten started on my restoration yet. Too many responsibilities right now. I am excited to know if your 68 version fits under your hood though. I am far from an authority but I understand the earlier versions were somewhat taller, however I suspect the taller ones are 67 versions, since the C4 (68 up)vettes body changed and I believe the hood clearance was reduced. Please keep me informed of your progress. (Pics would be great too!!)

The unit should come next week. We have a 427 on a test stand that I will put it on to tune before I install it on the Camaro. I will post some pic,s.

Well my tripower came in just before Christmas and of course I had minor surgery right after. I am really pleased with how complete and nice the system is for an ebay find. The picture of the 67 Camaro shows a 68 or 69 unit. The heater hose pointing up instead of to the front like a 67 tells the difference. The 67,s are over 1 inch taller. As soon as I can get around we will find out how a tripower fits under a non cowl 69 SS hood.

Got around to starting to sort the tripower out. I set it on a bucket next to the test engine stand and pumped some fuel in it. So many leaks I could not count them. Surprisingly the next day the gaskets must have swollen and I was down to just a couple but the needle and seats and floats worked perfect. Got some part # specific kits ordered.

NICE. That will be a cool looking set up.

Once installed you could tell people " it came in the trunk of your car when new, and the dealer installed it...."

Isn't that what the cross ram guys do? :P  ;D ;D ;D

No, they usually say it is factory original and very rare...  :)   What's really rare with these is keeping fuel in your fuel tank!  :)

The cool factor is what I am going for. Watching people at the cruise ins do a double take and probably that guy who (ordered one new just like it) back in the day. The fuel thing is a non issue. An L78 with 355 gears and my foot can,t get much worse.

Update, two of the 3 specific kits came in and I have them installed. While waiting for them and recovering from surgery I found several Utube videos on Holley carbs. I have what I thought was rebuilding them for years. The videos explained what the specific passages do, testing power valves, adjusting accelerator pumps, and other things I most likely overlooked. I also found some trash in one of the bowls that I said "how the #%@& did that make it in there". We are carefull about fuel filters ect. while not cleaning the inside of the air filter carefully. The open bowl vents tubes are the largest opening available. I found what looked like a string off a rag and a chunk of something in one that could not have made it through the needle and seat. I will be more carefull from now on to inspect the air cleaner housing any particles. One more kit and engine test.

Good post, and interesting topic and project you have going there!  :)    I, for one, would love to see some photos of what you are doing as you progress... and the YouTube videos you referenced would be a good addition... (I've always just rebuilt per the Service/Overhaul manuals...).
