Looking for chassis and engine photos 1970 GS 1971 1972

Looks like a 455 to me. No air cleaner support bracket so it is big car and you don't see the water valve for a/c, but like you said it's a very early book so who knows

 

In AC cars that hose to the heater valve was only 5.5 inches long and it looks longer than that. If it’s a big car it is a pretty rare one with no AC. Test mule is still my guess.?

 

The 70 ST1 4-speed for sale in the other thread has a tower clamp in the same location.

 

Almost too coincidental with the early engine picture to be added later, it would have been a hardware store worm clamp otherwise. I could not read the build date on the cowl tag of that brown stage 1 it was on.

 

Not a 7, there is a line at the bottom. Possibly a 1. Look at the other numbers on the plate.

 

I still say someone swapped those towers in. There is plenty of documentation showing wire clamps belong there. Try passing concourse with the towers on a Flint built non AC car.

 

Original towers have date codes on them. To add to the confusion year one offered date coded towers for a while. I know of a November and December built cars that both had wire clamps. I doubt January was different. I even got a short 70 style heater hose bracket off the January junkyard Skylark for $5. It went with my GSX.

 

If you guys are thinking about a rehab clinic please save me a seat.....

 

They reserved the rubber room for you already.

 

Duane will make sure the rubber is correct durometer rating.

 

At least in '68 the tower clamp was an option

 

That is proof that is a very early picture. I am guessing Buick was screwing around with 455’s in 68. If they only knew the stress this would cause us 50 years later after many are dead.

 

This is from an old Steve Dove book. He took all these measurements off an original car. A good painter like I worked with was able to work with these. Mine would not use the stencils. You can’t do better than this. Also every car was a bit different depending on how the factory guy put the stencils on.
