I am planning an old school mild custom for my '52 and I have a couple of books printed in the '50's that talk about "souping up" the stock inline 6. In both books they mention replacing the original Rochester carbs with Zenith carbs when moving to a two carb or three carb set up. Now, my quest...

I hope this does not seem too retarded a question. I was wondering if anyone out there knew what the realistic RPM redline is on a 1957 or early 261 inline six cylinder motor is. My motor was rebuilt stock and the only modification is the Pertronix electronic ignition conversion. I run the original 3 spe...

Hi guys I was hoping someone would have a starting point for parts for my '52 tranny. I've lost low gear and reverse just the other day (I had to push it back into it's parking spot, I had no idea my parkade was that sloped!) It sat for many, many years before I purchased so I'm hoping just the seals have gon...

Finally got to the cluthch & brake pedals that I got from Carl Stevenson's son last mth. They were out of a malibu & they fit up under the 52 dash not too bad, but "appear" to be a "little" short!!! My wife says thats fine for her as Janice is only 5'2" & look like the...

I think a thread on how to rebuilt a PG maybe interesting for some in the forum. All the picture following are with a Canadian (1953) PG already removed from the car. The major difference with the Chevy cast iron PowerGlide is mostly the bellhousing because of the starter side. At first, help yoursel...

Has anyone put in a late model Automatic transmission into their 287 Cubic Inch Poniac motor that they would recommend? I have a 1955 Chieftain Catalina that I am looking to upgrade the transmission on as the present one is really clunky. Thanks, Derek

Hi guys! I'm from the States, and I've been around old Chevy's all my life. I've had seven '53 and '54 Chevys most with 235's. My current Chevy is a '53 210 with a U.S. 261 in it that came out of a 1959 2-ton truck. I have some questions about the Canadian 261's that came in Pontiacs. Maybe someone here ca...

the old 261 in my 57 pathfinder is a little tired. I have a good 350 kicking around and I thought I would put it in while I get the 261 freshened up. The question is, what will it take to put that 350 in? Will it bolt up to the 6 cyl std. bell housing? I don't want to spend too much as the 261 will go back in,...

I have a beautiful 1957 Pontiac Pathfinder Deluxe sedan that i have restored original. The car has a 261 inline but i am not so sure that this is the original 261.

Hello, I have some problem with the automatic choke of my 261 . It is really too automatic !because the valve closes itself when I touch the accelerator pedal with a cold or a hot engine. I tried many things. Isn't it better to buy a other carburator? Where can I find a Rochester single bore downdraft typ...
