I am looking for a Air cleaner decal "Turbojet 430HP".Anyone know where I can find one? Repo is fine.
-
"Repro" stickers can be found on ebay. There's lots of vendors. If you google "Turbojet 430HP" a buch of options will come up also.
-
Tried all the places I could think of including Ebay and no luck yet.Must be a rarity.

It's more than a rarity - it never existed as a production item.

The only 430 hp engine of the timeframe was the L88, only placed by Chevrolet in Corvettes, and it did not use an air cleaner decal.. as the 'hood itself' was the top cover for the Air cleaner.. :)

The ZL1 was also rated at 430 hp. The few period engine bay photos of ZL1 Camaros show either no air cleaner lid decal or just the 427 crossed flags.

you're right William; I have always thought of the ZL1 as an 'all alum' L88... :)
and I didn't even think of ZL1 Camaros.... Is that what the OP was asking about? Does he have one? :)
-
The ZL1 didnt come to mind at the time,but I dont think I've ever seen a good pic of one either.I have an L88 for my 68 Camaro.
I did come across a Ebay seller that can make the decal,so I may go that route.

Someone over at Team Camaro makes custom stickers.. I had him make a couple for me a few years ago. 383 Turbo-Fire 425 Hoesepower sticker for my ZZ383 crate engine.

L88's speak for themselves... :) .. you don't need no damn sticker.. :)

I dont know,It ONLY has 430hp @5200......and its old Horsepower also. :)

From everything that has ever been written about L88/ZL1's, the horsepower is well above 430.. especially with headers to let it breathe. Chevy rated the L88/ZL1 engine at 430 (5 hp below the Tri-power solid lifter version of the 427) .. I suspect to discourage orders of the engines by the 'typical buyer'... Only the most informed racers knew of these engines at the time... :) ...with headers and supertune, I doubt that 500-550 hp is out of line..
-
Old Chevrolet engineering dyno test show 575@6800rpm for the ZL-1. Mine was right on that figure.

My comment was tongue in cheek.. :)
I have done a bit of research the last couple years on the L88/ZL1 also.Theres not alot of info out there on these.From what I have come up with and having seen a couple dyno charts on them,they are quite impressive.GM as you stated wanted to discourage sales to the inexperienced and also due to the scutiny from the insurance companys they kept the HP rating lower.GM could not mis-state it for obvious reasons.Whereas the 427/425 and 427/435 engines were peak hp ratings they used Approx 1000 rpms below peak rating on the L88/ZL1.(430HP@5200) The dyno chart I seen on the L88 (1967/1968) with headers and good tune produced approx 557hp@6400.The ZL1 produced 585hp. As you may be aware in 69 the L88/ZL1 had a redesigned head/pistons with open chambers, venturi ports which breath better and a change to the camshaft which would account for the increase although the factory rating was not changed.
IMO the second design L88/ZL1 was pinnicle of success for Chevy.By todays standards maybe not so much,but going back to the late sixtys and to see how these were beefed up.7/16 pushrods,7/16 rod bolts using Boron steel with ground shanks,etc.According to my old info the L88 with a valve spring change (which I have done)the Redline is 7600 for drag racing and 7200 for Circle track(like Daytona).I paid $4500 for my L88 engine in 1982.
I think it quite fitting that it be nestled into my 68 RS/SS :)
My Camaro will be stock looking on the outside.I dont expect the project to come to fruitation for 1-2 years.After this project is complete,I may build a 496 bb engine as a spare. :)

Thanks for the dyno chart.You posted as I was typing.lol
I had thought the L88/ZL1 to be in that ballpark.

What is the deal with the Vacuum can in the L88 pic. ? There is no port.

Check out a more modern ZL1 dyno test on the engine from #26:
http://www.camaros.org/copo.shtml
With today's 0 weight racing oils and the latest piston ring technology Camaro Hi-Performance is seeing 550hp+ on their ZL1 rebuilds.

L-88 AND ZL-1 did not use vacuum advance, only mechanical, as they were intended to be strickly race cars. So the stock vacuum can is factory sealed. These motors run much better with an adjustable vacuum can and manifold vacuum advance, as these motors love LOTS of advance due to the high piston dome.

Man, the idle of a l-88 or a ZL-1 is like NOTHING out there! your going to love it!

That vacuum can operates the wiper door that covers the windshield wipers and linkage on '68-'72 Corvettes.

So would you recommend a Vac Distributor for "Hot" street use? I was going to go with a Small cap MSD with mech advance.Even thought the L88 doesnt have much vacuum, I think I can get things to work ok by tying the systems into the RS Vac tank.

12.5:1 compression ?
If you plan to run a MSD checkout p/n MSD Programmable Digital 6AL-2 Ignition Boxes 6530. More to chose from, but appears a nice street/strip unit. Very popular with the bracket racers around here--can take some timing out at shift points ,launch etc. based on track conditions. Very user friendly with laptop. One of my buddies chases points ,and installed the next unit up last season. Loves it. He has a 900+ HP BB which puts his Camaro in the high 8's ( and on the rear bumper once) His daughter runs the car around a mid 9 dial. If I was going a different path with my Z , A MSD set up would be my ignition system of choice for it. Proven in our Gasser. Probably more a TC response, but thought I'd add.

Yes It still has the 12.5 pistons.I will check out the 6AL-2.Thanks.Not that I will do anymore street racing (unlike my younger days)Just going to drive around with it and enjoy it and also try not to break it.lol

Racing aside, I see the benefits of integrating some modern technology into these older race bred engines. Drags are easy, make a pass ,back to the trailer to cool off. Street is far more demanding. Plus the benefits of soft hit rev limiters.....when Shut Down comes through the speakers, and your right foot gets a little heavy ;D

To clearify my ? (Vaccum advance diaphram) not can . So why is it there if it has no funtion?

The vacuum can still has the advance rod, although it does not move, the rod still needs to hold the advance plate in position and limit it.

Thanks for the explanation. I figured they would just lock the breaker plate with a screw.
