Mr. Wizzard

I'm not familiar with your injector set-up, but my cross-ram individual throttle body combination works wonderfully. I have have a vacuum "plenum" of sorts for the MAP sensor, and I'm using the Holley Dominator ECU.....which I might add, has tuned itself! Throttle response is instantaneous....it'll "bark" at you.
It cranks and lights off quickly, regardless of temperature, and I couldn't be happier with it. While I still have plenty to fool with on my car, screwing with a carburetor isn't part of it.
Perhaps you should have used a combination from Kinsler. Their linkage is like jewelry...

Mr. Wizzard

It only took me eight years to make my lightweight C2 instrument cluster. It uses the custom Classic Instruments gauges I've been using in my flat panel dash. I even planted a clear shift light in the center just below the turn signal indicators. Couldn't resist putting my company logo in the trip odometer....
Overall, I think it's a great improvement.

Did you make the faceplate from a 63 cluster or have you own cast? I know there was someone trying to make a plastic cast cluster like the original light weight GS parts.

Mr. Wizzard

We pulled a rubber mold, (actually three) from the piece that's in the car. It began life as a broken C2 cluster I found on Ebay for $200.00. After a lot of welding (really touchy with pot metal), grinding, sawing, etc, I was able to reduce it to essentially a flat backed panel. Making the gauge buckets accept my Classic instruments also very time consuming. The instruments mount in from the back-side, so they.re essentially pressed into place from the rear. I'm using non-GM accessories because they're too bulky and heavy (remember, I'm all about weight). I cast small housings for the LED's (turn signals) from Devcon Liquid Aluminum and they fit in the back-side like they were made for it.
After a lot of cursing about junk Chinese lights, we found that those little LED's are sensitive to positioning (positive/negative)!
Once I get a descent part from my latest mold, I'll replace the cluster, but right now, I'm really digging the way it looks.

Just bought this a couple weeks ago.

I took the decals off later.

Congrats!

Mr. Wizzard

And now the grill has gone black along with the rest of the side trim. I like it...

Wow. That photo is stunning. I enjoy this Gran Sport thread a lot..!

Thanks, the Grand Sport thread is my favorite

Mr. Wizzard

Just happened to notice that the Brawner Hawk Indy car's Halibrand's look an awful lot like the Halibrand's used on the Grand Sports....

Thanks for posting that, Larry. AFAIK, what we affectionately refer to as Grand Sport wheels were originally designed for Indy cars.

Fellow 1963 Grand Sport fans! My 2017 Grand Sport, Tribute, is in the running for the Corvette Forum's C7 of the Year and is the ONLY 1963 Grand Sport #001 Tribute Corvette that I know of. If you have a spare second, please consider a vote for Tribute. Thank you!

Here's the link for voting: https://www.corvetteforum.com/forums...fications.html

And here are a few photos showing most of the tribute paintwork along with my 1963 #001 GS replica. (Big announcement coming soon about the replica...I'm taking it to a new level!)

Question what intake did you use on your 001 car ? looks like it matches up perfectly with the 66 cold air hood. All the GM intakes I have found are too tall for that hood. ------- Ken

Hi Ken...it's a custom hood, which is why it matches up perfectly.

I used one of the Mongoose 66 cold air hoods on my 66. With the factory intake on the ZL-1 I had to raise the center of the hood blister almost two inches. It sort of destroys the look I wanted. Just trying to find out what intake is used to get the proper carb height to use the hood as built. My GS uses the louvered hood . ---------Ken

Does anyone know if a 66-67 round (chrome lid) 427/390 HP Air Cleaner assembly will fit on a new Holley 870 CFM, 4160-Style 4-bbl Carburetor, used on the ZZ502/502 crate engine?

The ZZ502/502 is installed in my '63 GS roadster replica.

Thank you for help on this one.

Good news on my GS. Discovered the problem with the Hilborn EFI. My slow throttle response problem was caused by some gas issues that I had late last year. Seems The throttle shafts were coated in varnish which made them tight in the injector bores causing the throttle sluggishness. Andy from Hilborn was here today took everything apart cleaned up the throttle shafts and bores and butterfly's. Reset everything and we took it for a ride and it runs like it should ! I also now have 100 % throttle with some adjustments. Only had about 85% before. One of the wonderful issues with 10% ethanol in the gas here and a very short shelf life of the product compared what it used to be . ---- Ken

Mr. Wizzard

That's wonderful news. I really hated to think you'd end up running a Holley 4-bbl on it. Good work!

Very interesting informations here, thanks.

I look for specifically this halibrand 5 pin replicas with such golden line rims for my GS replica. I think front wheels 8 " and rear wheels 10". A friend told me, that the golden lines and letters are painted. But perhaps I can buy exaktly this combination,if they would be available. For me the best combi for my GS.
I have a set of original 6 pin halibrand 8,5 " from a GT40, but it´s to complicate to adapt and the real wheel is to small I think. Also 5 pin is more original to the GS.

I would be happy for a tip.
