Well, I knew it was only a matter of time before my stock carrier bearing when boom, and it did!!! I guess a heavy wagon with tons of horsepower, a 4 speed manual, a poorly designed driveshaft and a driver that likes to stand on it don't really mix. Since I have no intentions on changing my driving habits,...

Now that' I've solved my wobbly driveshaft issue, I'm looking to swap out my rear end with a replacement unit. I've got a refurbished 3.08 POSI in a spare housing complete with axles ready to bolt in and go. I will be re-using the drum brake assembly. Any idea how long it will take doing it driveway sty...

Well, here I am back again. Just confirmed the gear ratio on the Camaro diff going into the 39 Chevy is 342:1. I believe the diff gear ratio on the 60 Pontiac from which I harvested the 261 engine and 3 speed standard tranny was 355:1. The car from which parts were harvested was a 60 Pontiac Strato Chie...

I am finally completing the rebuild on my 261 ci from a 1960 Pontiac. Don't know how this escaped me before but I cannot find any timing mark on the harmonic balance wheel nor a pointer on the engine. Is this normal for this engine, and if so, how does one set the ignition timing? As a matter of interest...

I got a quote for installing a new carrier bearing and balancing my drive shaft. Good thing I was sitting down. $700-$900!!! Maybe I made the mistake of asking for a custom unit to be fashioned out of titanium plated narwhal tusks. Must be a Vancouver thing, but it sure makes keeping these old rid...

so my straight six has been running rough lately and it sounds like it's miss firing. I changed the push rods recently but when I did I just tightened the rockers by feel. I'd like to go back and tighten then to the right torque pressure. Would anyone know the amount of torque pressure to use? The engine i...

Hey Guys, Having a little trouble with the PG that I am putting into the 61. Its an aluminum PG from a 72 Nova mated to a 350.

The oil dip stick on my 250 straight six engine was broken when I got my car. And I'm having a hard time finding one.

Looking for a source to purchase new hydraulic lifters and cam for 60 Pontiac 261 cubic inch. American sources only have solid lifters and cam that was used in US Chevy trucks.

I took the 2 piece drive shaft out of my spare frame today. Look at the shape the carrier bearing is in. It's one of those parts that I bet goes unnoticed and unreplaced. Imagine how many nice cars are driving around with their original, crappy bearings in them. This one is toast. I'm going with a urethane...

I have two 62 Parisiennes, one ragtop for fixing, one hardtop for parts. Ragtop has sat for 14 years. Hardtop has sat for decades. I haven't verified yet, but they look original, and I assume they both have cast iron powerglides like most of my Pontiac / Chev cars of that era. Question is: How do these tra...

No matter what I do and what position the turn signal stalk is in as soon as the car is started the right turn signal starts blinking and there is no way to turn it off short of removing the flasher unit. Any ideas what gremlin might be causing this issue?
