I would strongly suggest reading Ch 8, page 8.1 in shop manual to understand the ventilation.

The ventilation from top of engine, under intake, to PCV Valve, to inlet under carb at intake to carb insulator (circled in green from shop manual picture) is the same regardless of what state the car is from.

For California emission cars the oil filler tube cap  (circled in orange) was sealed and ventilation was instead recirculated from left valve cover directly into the air cleaner housing and drawn into engine via carb air as indicated in the serviceman bulletin I provided link to.

You indicated your left valve cover has a vent hole so assume you have a California car. Regardless, your ventilation from top of engine to carb insulator should not be disconnected or blocked and should have the PCV valve inline before reaching the carb as seen I diagram below.

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…
