I was thinking of rebuilding My TH400 in my 65 Parisienne. As I know this is not the factory trans so I was wondering if I should put in something with overdrive like a 700R4. What seems to be the popular transmission choice if not original

Guys, Can you help me figure out what I need to complete the power steering bracket setup on my 67 327? In mocking it up before paint, I think I have the correct 67 pump cradle bracket and pump. The bracket that goes across from the motor mount boss to manifold is a maybe, but it appears I've misplaced the re...

I suspect there are many others on here who love searching out parts for their old cars when they do conversions, upgrades, whatever. I am almost done my 427 conversion and am making an effort to keep it looking very "1966" as much as possible, but I'm still on a budget (part time worker, you know....) An...

Would someone have a dipstick and tube that they know is from a 68-70 B body 396 427 or 454? I would like to get some dimensions off the stick and tube. I suspect I don't have the right pieces for the oil pan I have on my car which is from those years. Thanks!

When you get tired of me posting up about stuff you can still get new from GM, either just tell me, or ignore these posts! When I was working on my engine swap I noticed my clutch fork boot was basically junk, full of cracks. Low and behold, a part number changeup later, I had a current number, ordered the bo...

So for my upcoming swap I decided on a LUK clutch. I have always heard good things about them but recently someone on here had a bad experience with one. However, I decided to go with a LUK in spite of that because the dealership I work at buys a lot of jobber parts from a local supplier. We buy so much there th...

Guys, What would you recommend or have an opinion on, as to which pressure plate, clutch disc and flywheel I should consider using with my 327/M20? There are so many choices out there from total economy from Carquest all the way on up to high performance (high cost) from summit. I do want something at le...

I have a 65 Parisienne rag top with a 12 bolt rear end. I did a rough spin the tire and count the drive shaft revolution and came up with 2 possibilities being a 3.08 or a 3.23 ratio. I thought the 3.23 was the more accurate but after some reading was not sure if this was an original option (maybe it was change...

How do you clean these small passages that go down into the manifold? Where do they actually lead to? Do they enter the exhaust crossover some way? Thanks, Mark

I was ordering parts for my engine swap today and this came to mind. If this has been covered here in the past, forgive me. I thought this is important enough to put it out there for anyone converting to a manual trans from an automatic (possibly only Powerglides, not TH350 or TH400) on a Chevy engine in th...

Probably probed in detail already, but just as a quick question if I may, Can I use my existing 65 pedal support and simply add a clutch pedal and corresponding smaller brake pedal?

Has anyone here ever plugged off the Carb base heat crossover passage ways on a '68 327 with 4 barrel manifold. The '68 has exhaust running right under the front of the carb. And that gasket can burn out making like a permanent open EGR. If someone has done it, what was used to plug the holes? Pound in plugs...

In looking at bearings on line for my 67 327, there seems to be many types and different manufacturers to choose from. I think I'm just looking to do standard size bearings. But I'll take some good measurements of the crank journals to make sure. What should I be looking at? Any suggestions on which dire...

Cleaning my 327 cast iron intake. I'd like to take the heat shield on the bottom off. I think to clean it properly it needs to come off. Can it be removed...then put back on? How is it even fastened? I haven't tried prying at it yet for fear of damaging it.

This week I needed to remove the pilot bushing from my crank. I've always used the old method of filling the back of the crank as well as the pilot bushing with grease, then tapping in an old transmission input shaft. This forces the bushing out of the crank using hydraulics, the grease does the work for y...

Can anyone tell me what I'll need to fit a rad in my 65 when the 327 goes in. I've been thinking of all I'll need, but I'm kind of confused as to the spacer/shroud configuration. Below is 2 pictures of a 65. One (327) has the short spacer/rad/shroud, the other (283) has the wide spacer/rad/no shroud. How s...

I'm trying to pull the 327 Damper, but it will not budge one iota. It's deflecting the arms of the puller. Do I need to heat the damper to crank flange?

Guys, I took a head off my 327 today to see how much of a ring ridge I had. Turns out there is just a hint of it, in some spots I can't feel any. The engine had less than 50 thousand miles on it. So I'm not going with an overbore. My cheap 327 budget plan was to cut the ridge, and just simply replace the piston with n...
