For the, externally balanced, 303/324 based 371, only. Three belts for Air conditioning, two belts for non AC.

Your profile shows an Olds with Tr-Power. Is it a Pontiac engine, or was a Pontiac manifold adapted to an Olds?

Or is there another explanation?

It Is Olds 1957 371 c.i. V-8 Engine , i.e. Either Olds G M C Part #'s Above I Listed = Harmonic Balancers Will Work Irrespective Of Belts Or A C...

1957 Version (See My Photo) Fits 1957,1958,1959,1960 371 c.i.V-8 Engines...

Thanks...

Your use of caps is unnecessary.


In that case, I'll repeat the second, and third, parts of the question:


Since J-2 manifolds/carbs are more plentiful, I see no reason to adapt a Pontiac manifold to an Olds engine.


OK, you do not have air. This one should work for you.




Not very useful. Could be anything from '49 to '58. Your valve covers are '49/'50.


Yes. Both 303 and 394 based 371 should use the same balancer. Damper Doctor will know for sure.

My Valve Covers Are 49/50 Because I Have Hi-Lift Engle Cam, Solid Lifters And Isky Adjustable Rockers ( Fit Easier Under Covers ) Ain't Got Nothing To Do With Anything...

It Is 371 c.i. V-8 Engine 4 bbl Or Tri-Power Carburetors Is SAME,i.e. The Harmonic Balancer In Photo Will Fit: 1957,1958,1959,1960 371 c.i. V-8 Engines...

G M C Are Factory Numbers, For 1957 & 1958 Harmonic Balancers...They Can Be Rebuilt, But I Need Used Or New For My 2nd Engine Building Now...

No problem with oil leaks?

Isky was the only one with the adjuster on the bottom. It was so it would fit under all Olds valve covers. Good for "sleeper" situations.

I used factory adjustables and "dimpled" covers with my Isky cam.


A simple comment. Nothing more, nothing less.


Is English your second language?

Is Espanol Englese Your 1st Language... You Pretend You Think You Know What You're Talking About...Forget It...

Explain.


In a language other than English?


I asked a couple of simple questions.

Questions that you do not seem to be capable of answering.


English is my only language.

I do not use it, to flame/insult/deride someone who asks me a simple question.

I do use it, to answer any/all questions, about my posts, posed during a forum discussion.

It is the way adults comport themselves.


You have me confused with 91buickman.

I was simply asking how you got a Pontiac intake manifold to fit your Oldsmobile engine.

Nothing more, nothing less.
