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...

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'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...

As the subject heading asks. Does anyone have info on how many 396 and 427 cars were built? I can find that 10 2+2 convertibles came with a 427 but what about other applications. The VVS I got for my 69 396 2+2 only indicated that 1943 2+2 coupes were made but no power train break down.

my 67 impala instrument cluster was rebuilt many years ago. It seems that every year I have a noisy speedo cable. Pull it out and lube it but not perfect. The speedo needle has a minor fluctuation but settles down after a bit of lube. It seems to be a yearly ritual. The transmission is 3 speed th350. Any...

looked at a number of sites and see all kinds of different answers. 60 over I think all would say ok but what about 70, 80 or 100? what do you think about sleeving back to standard? This also has to do with saving an original 66-69 427 block

Hi.. Went for a drive on Friday, temperature was 85F +. Car runs at 180-200 F most of the time, cooler on the highway. But Friday the temp was up over 210F driving thru town. Might have got to 215F but I was back on the highway in a few minutes and she started to cool down to 190F. When I got home in the garage I l...

Yet another incident that I cannot explain, hoping someone here can. Rocker tension seemed ok, can tell in the images that the nuts are not loose. Replaced the bent rods, replaced the rockers with roller type, then the other side did this:

Hi guys, I recently installed a new carb on the 68 2+2 and I am wondering what this rubber hose is for, coming out of the bottom of the breather. Does it attach to the carb somewhere or does it just dangle ? Regards, Scott (LandShark ...)

Hi all, so the F40 RPO all our aussie cars got is for heavy duty front and rear suspension. I know that means 4 link and possible shockie ratings but what is the difference for front suspension over standard? Just shockie ratings? cheers all.

I have an aluminum rad in my 67 350 crate and air conditioning. I have a flex fan and a spacer to position the fan. What I am experiencing is the temp continues to rise when left at idle for a few minutes. The temp will go to normal once I get moving and get some air through the rad. I want to consider putt...
