Well I understand your confusion. Based on what you say everything should be OK. I am stumped too.

do you have access to an oil pressure gauge?

Just seems crazy that it would be equally distributed over all the cylinders and not just one.
Did the guy that did the heads know Nails? They ALL say they know, but are you comfortable with his...

Safe to assume you squirted some oil in the cylinders after taking the first compression test to see how it changes?

I don't want to assume...

wouldn't a compression test be a good way to be certain about whether it is top end or bottom? Maybe this is already known? Or at least narrow down to a particular cylinder?

Hey guys,
Some of you have seen my Riv build. I am selling the motor due to a change of plan. I am going tri power 425 now.
What I have is a fresh 401. Rebuilt maybe 4000 miles ago. Not a single...

Thanks Walt,
I figure it may also be good for people doing their own projects to to see a step by step deal.

Even better for the future owner to see how it was really done!!

There have been SOOOOO many folks who spent good money on the Hirsh "Buick" red paint and ended up being disappointed. Plus, they never returned my inquires after spending $40 or so on a quart.

Shaving some trim, emblems, and door locks. There is a fine line in shaving and I do not want to cross it.

TH400 is definitely awesome. isn't the TH400 a 2.48 first gear? The 200 is a 2.74 and the 700 is a 3.06.

Plus, the 200 has a .67 OD. Now that is cool.

The 200 is a great trans. Plus it is about 3.5 inches shorter overall. Sometimes that helps. my X frame needed it.

Just put one behind a Nailhead in my 65...here:

I am doing every bit of it myself. Hard to say how much at this point. I am going mild custom on this one.

Installed the engine and overdrive trans today. check out the pictures

Hi Guys, Check it out and follow along if you like. Ground up build with photo documentation all along the way. Click the "become a fan" and get updates automatically. Probably about 4 or 5 more...

Yeah, I figured if I have to take it off, I'll be doing more stuff including the updated front seal.

Can a front rope seal be R and R'd without taking the timing cover off?

Forgive the moronic question if it is in fact moronic

TA performance suggested their c110 cam since I do not know much about the compression of the engine.
I did learn that the casting number on the rear is 1238861 which says it is a 71-72 block. But I...

The vehicle is a 71 Riviera.

I am thinking about maybe a low RPM cam to help off the line. I am trying to weigh the difference between $1K on a rear end gear change and $1K in engine mods to make...

Thanks for all your comments, guys. The purpose of the car is simply cruising...and not really even too much exhibition of speed. When I saw the psi numbers and did some research, I thought maybe it...

Hello, I am new to this car and to 455 Buick engines. I have a 71. I did a compressions check and all cylinders are about 125-130 consistently. I read previous discussions and they have lead me to...

Sounds like it can be confusing.
Is there a dependable reference source to learn all the nuances of the 1950 model year?

Some books have multiple errors

Pardon my ignorance and believe me I have tried to find this information on the net without much success.

I am in the market for a 1950. I prefer the jetback model at this point. I have learned...

I just got another ebay scam sent my way.

It is in the form of an "unpaid item" dispute. It basically says that somebody has filed an unpaid item dispute against you and you need to click the...

Also beware of emails that say you have bid on an item you have no knowledge of. If you click on it to find out what they are talking about, they usually have you sign in. That is a false site and...

I have heard that some aftermarket head gaskets are actually a bit thicker and therefore they lower the compression. Don't know if it applies here though

Do any you fine folks know where I can find some of the acorn nuts holding the skins onto the early Riv's??

I know I can replace them with something equivalent, but I haven't seen aftermarket...
