Got pump put bk on.  Poured in some AF into the pump.no sign of leak but only poured in bout 2 or 3 quarts.down the crossover tude directly into pump.  Dnt kno if that will indicate further leak or not but thought worth a try before re hooking everything bk up.

Regardi g fat o ring.  I had a little bubble up there on first fill up, wondered if two would work.  Anyone tried that? 2 w sealant?

Yes,  i nvr got it started and the leak was coming out of bottom of seal.  Unless pressure builds during filling, shoukdbe any pressure shouod therr?

Other thing is, these are like fat little do nuts, as opposed to  a sk8nny little o ring.   . 2 is ok?  Less goop

I dealt with the same leak when I changed my water pump a few years ago. Rather than using 2 O-rings, I turned a sleeve that fit on the crossover tube fitting and forced the O-ring down into the water pump and it worked great. I think I ended up making it about 1/8" thick. You could probably get the same effect by using washers if you can find some the right size.

Ok, thanks

Well, i got it put back togeterher up through the crossover pipe.   Filled it up,to bout inch from top of radiator.  No leaks, albeit not under pressure. So late today or tomorow,  hv to get oil parts back on, and starr tonight ir tomorow.

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
