Decided the other day not to drop the 283 back in without a full refresh. When I took it out, without having driven the car, compression was 130ish after 30 yrs in storage and a real bad timing chain, it ran quiet and didn't smoke so I was going to run with it for a couple of years. In the end, it has 130,000 m...

As part of my engine refresh, see that post for greater detail, I ran into a problem with lack of sufficient clearance between the front of the starter and the new Magnaflow 2-1/2 exhaust connected to the ram horn manifolds. There was less than 1/8 clearance which would have resulted in the starter ov...

HEY GUYS, OIL PAN NEEDED FOR A 283 OR 327 FROM 62 T0 64. THANKS. SOUTHERN ONTARIO

I know the 63s still has a short shaft with the coarse spline. But did 64s??? The chevelles used the long with a fine spline output. That's why I ask.

Changed 2 barrel to a quadrajet on my 64 Parisienne. Have tried adjusting it but can't seem to get it to go into passing gear. Any thoughts?

On a vintage engine (283),.. how nessesary (in reality) is it to add zinc additive to the engine oil. Anyone out there have engine parts failure because they didn't use it. ?

Hi Everyone, I hope October is offering up nice driving weather for you! I've entered the world of no spark again. I have this 45-year-old HEI distributor and coil installed. I tested the coil with an Ohm meter (as well as jumping the spark) and it appears dead. Most HEI distributors have the coil mount...

Not exactly Pontiac but does anyone know what color a 6 cylinder in a 62 Canadian impala would be. Found a rusted out 62 4 door but has a 6 cylinder and its green just like a pontiac 261. Could not get at block casting number but stamping number is W9216635 could not find any information on this stamping num...

Hey guys I just bought a 1962 Strato Chief in Edmonton - 3900kms from my home in Toronto and I intend to drive it home in a few weeks. I am having a mechanic look it over before I take off but any suggestions of things to look for before I take off are welcome. It's got 100k original miles on it and seems to be in g...

Hi guys, I got a freshly rebuilt engine (Chevy Straight Six 230) that was driven for the first break-in about 100 miles, drove great then issues started with carburator.

I am in processes of installing a refreshed 1960 261 'Strato-Six'. It has a remote oil filter. The Pontiac manual says 4qt plus one for the filter. I have 5qts in it and the dipstick is right at the 'low' mark. Either I have the wrong dipstick, or perhaps this should take 6qt, like a truck engine. The...

What's the process for switching my car from a generator to an alternator?

Bake · Bake

I am a proud owner of a 1960 Parisienne 4 door vista hardtop. I'm swapping the original 261 for a period correct 283. I found a 283 and transmission in a 1966 Parisienne for a donor. Then I found that the transmission on the 283 had a "fine" spline while my driveshaft has a "course" spline. My first thou...

So I decided...a while back...after I discovered that my new dual exhaust didn't actually run all the way back...that I would do something about that. My 63 283 2spd did not come into this world with a dual exhaust but I feel that it's a good upgrade. My car had that partially done. Nice new 2" down to stoc...
