Big block conversion thread
(Preview)
So a site member and I were talking about him doing a big block swap on his 66 Grande Parisienne, (currently a small block). He said when the time came he would be asking me about certain things he was unsure of that may be required for the conversion. That triggered the idea to do a big block swap thread. I w...

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...

67 and older 4 speed shifter restoration
(Preview)
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...

(

(Preview)
Hi guys I pulled this out of a 67 Pontiac GP lately but have no plans for it myself at the moment. It was not original to the car but the date code on the intake indicates it is a 1967 build and the engine number indicates it came with a Turbo 400 which is still attached. The engine/ tranny is very very complete...

1966 Fuel Pump for 396 or 427
(
1 2 3
)
(Preview)
When I rebuilt my 427 a few years ago, I wanted an original looking fuel pump but wasn't eager to pay the price for NOS. The fittings on the 66 pump didn't carry over into 67, so in Canada it was a unique pump. I think the US cars with a 396 in 65 used the 66 style pump but of course we never had them here. I bought...
