Originality / 68 Big Block Radiator Codes
« Last post by rod396 on June 26, 2017, 02:55:11 PM »
I am of the understanding that the 67-68 Big Block radiator code on the pass side tank for manual trans is "OL", and this is for a 4-row core (?) but I can't seem to find what the code would be for a 23-inch, 3-Row core, Big Block, manual trans.

Does anybody know what the correct code for the pass tank would be? Original/survivor examples.
Thank you.

Carb is hot.  Not the fuel line.  You are cooking the carb.

Mild Modifications / Re: The Hugger goes ZL-1....

Weve had a Midsummers holiday here in Sweden this weekend but I managed to get some hours off to continue the build of the ZL-1. :)

A proper, and hopefully period correct, fuel pump from AC Delco have found its new home:


The aluminum water pump is also in place now:


Since I choose to use the factory installed exhaust manifolds, they went in as well:


Rocker covers made the all the parts getting more and more looking like a real engine!




Its always something missing so Im waiting for some parts from US & A to arrive...maybe in the next coming weeks?!

I'll have look, it's a factory 3.55 12 bolt posi, from having the cover off, but I haven't looked at the numbers on the tube. It has the round rod traction bar.

Thanks for the reply, I will sure post pictures whenever it's done. Right now I drive a set of FC wheels (drums brakes) with P-01, Firestone wide oval redline and it looks great.

I'm planning for my second set of FC wheels, to have them painted yellow, with dod dish and Goodyears Wide Tread F70-14 white letters.

Also have a set of rally repro 15x7 with BF Goodrich.....

Your carb is too hot and it sounds like the fuel is boiling. You don't say what intake you have but make sure you have the right gaskets between the intake and carb.  Here's a post on the subject from the Corvette forums:  https://www.corvetteforum.com/forums/c1-and-c2-corvettes/1978466-q-jet-carb-base-gasket-tech-info-the-hot-slot-manifold-problem.html

The XT wheels I have are all black with car color on the cap side only.
 
I hope you like the yellow. I found it to be too much yellow & added trim rings to mine. That's just me though. Love to see a picture when you're done....Joe

Originality / Original wheels paint for dog dish

Hey guys I'm planning to paint a set of OEM steel wheel and have dog dish installed to them. I know the outside of the wheels is suppose to be painted the same color as the car (Daytona yellow for mine), who about the inside ?

Does all the wheels we're originally black for the factory, then only painted on the outside the same finish color as the car ? Or the inside was also painted ? Or it stays in black ?

Thanks to all

1968 L48
Headers
1965 #461 heads (1.94's)
Comp cam XE262H
Cast iron intake, Q-jet
180 thermostat

Temperature outside was 93... although this has happened at lower temps also... in the 70's

Car runs fine for about five miles and then when you come to a stop it stutters and stalls out.

Opened the air cleaner operated  the throttle no fuel, only a little vapor.... poured some gas into the carburetor and could hear it sizzle!!

Fuel pump was hot to the touch, so I got a bag of ice and set it on there for about 20 min. Car started after that and I was able to get home. This is happening more than one occasion

Insulated the fuel line near the rear tail pipe with high heat tape, had no impact. Thought that was a problem because it was only a half of an inch away

Here are a few shots under the hood, I have the steel fuel line from the fuel pump to the carburetor and you can see the distance from the rubber hose to my radiator hose, and my steel fuel line to my headers.

I'm not sure what to do here other than perhaps and electric fuel pump. I do not know what temperature the engine is so I will put a gauge on it this week and see if it's running crazy hot. But the car did not overheat at all.

Any ideas suggestions comments?

Thanks everybody in advance
