Removing Exhaust Manifolds

I have written on this subject over the years and will repeat my experience in parting out almost 60 63/64's over the past 25 years:

It is indeed much, much easier to remove the exhaust manifolds with the heads (or complete engine) removed from the car. I have never successfully removed an exhaust manifold that has never been removed from an engine while it is still in the car and would never attempt it anyway knowing what I know now.

Three Driveshafts used in 1963 & 1964

There are 3 driveshafts used in 1963 & 1964 Cadillacs.

Since the Hydramatic transmission was longer than the “new for 1964” Turbo Hydramatic transmission, the front section is shorter than the ones used on TH equipped cars. This basically means that all regular body style 1963 Cadillacs, and the "62 series" 1964's came with the driveshaft…

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 13 Comments 0 Likes

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…

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
