It can be smooth when the bolts turn like new. Even the lines came undone. No rust. Drivers side needed the Vice Grip, but only just (because I wasn't willing to wait for the PB Blaster to work). But I'm sort of worried about the flex line to main chassis line. Cracked it open and pulled the axles. They hav...

I figure I might try to document the conversion of the 65 Laurentian, from power glide to a 4 speed Muncie M20. I'll ad that Carl Stevenson has been a invaluable resource on this conversion, and has helped me out immensely. thanks Carl! And be sure to check out Dave's conversion post sticky as well. I'll...

I've decided to make an attempt at "tightening up" an original shifter for my 66. This is the same shifter body that was used in Canadian Pontiacs, Beaumonts, Acadians, numerous Chevrolets and I think maybe some Buicks prior to 1967. I have it all disassembled and need to order some parts for it. Fo...

I've thought it might of of interest to document my TH400 build, hopefully sparking some discussion around of what is best. Like my rear end build, the transmission was originally one of those things "Black art" and best thought as being left to the pro's. I have had very good success with my 12 bolt bui...

So.....I was thinking about my grandfather recently, and a random thought came to my mind and of course it got me thinking. I have a memory of being with him at a gas station in the 1980s. I think we were in his 1977 Buick LeSabre. It was a full service station and my grandfather opens the trunk. He gets ou...

Gurus; How do I get my Qjet to come off the choke a little quicker in the cold? On my 327 when I rebuilt it, I did the partial restriction of the heat riser passage at the intake gasket, and I used a gutted heat riser as well. Even when I see 180 on the gauge, she still stays on high idle when out on the road, until...

Im in BC, any recommendations on companies that sell crate engines? I talked with CCE in Burnaby and they seemed good, but im sure you guys have been through the process of buying one or two. Love to hear your take on this. Thanks Woody

I have a 1969 Pontiac Grande Parisienne 4door 427 V8 335 hp , but it has dual exhaust. It is original and my grandfather bought it in 1969 from Roy Pett GM in Lindsay Ontario. It has never seen a Canadian winter. It went to Florida until 1981. Stored for 28 years it looks a little rough but it is all there. A li...

Tonight I went on a mission. I'm trying to sort out what bench seat shifter handles fit what cars, and what each one looks like. Quite a bit of info online but from what I can tell, LOTS of wrong info on this topic, so I dug into the limited resources I have. From what I can find, from 64-67 Canadian Pontiacs...

What physical differences are there between an automatic coded Q-Jet compared to a manual one? I have a 1967 7027202 as came standard on my 67 327 automatic.

New extra long cable to the 4 speed. Needle started off decent, but now is bouncing wildly. Any solution to the issue? Anyone experience the same? Thanks, Mark.

Question; Can one change a SBC 2 piece seal with the engine in place, in a 65 B Body? I have just detected a small drip in the 65. Don't think its the pan. If it stays this small I'll not worry too much. Second, Will this wee drip eventually foul my clutch?

So installed new diff. On removing driveshaft, the uni at the diff was tight. Removed and has strange wear patterns. How do you adjust the pinion angle on the 65s when they have a 4 link rear?? Cheers

Was there ever such a thing as a 3.23 ring and pinion for a 8.875" 12 bolt? The reason I ask, is in my thinking, it would be a great on road compromise ratio for a big car with a M20. And I'll be building a 4 leg 12 bolt for my 65 and already have an good open 3.08 carrier. My current 10 bolt has a 3.36 since it was a s...
