Hey guys can you guys tell me what vehicle used this engine...9773153. The is the block casting number. That is all i can see right now maybe later on i can give the date code. I know its a 326 CID from 1964 but what vehicles used that engine is what i am interested in.
Thanks
Gabriel

There's a three digit code on the front of the block on the passenger side next to the timing cover. The first digit will be a "9." The casting number is definitely a 1964 326 block.

Q

326 Lemans

You're just saying that because they never put the 326 into anything else that year. I should have caught that myself. Well, at least with the block code we can figure out how it was built at the factory.

Q

Is that the same as saying it was in a Tempest? The models we had up here in those years were different from yours. And to dispel a myth (conveniently started by some SCCA Trans-Am competitors I'm sure), all Firebirds and GTOs had Poncho engines, not Chevy engines (until the advent of "corporate engines").
I almost bought a 65 Pontiac Parisienne (Grand Prix body style I think) with a factory 409 for $250 way back, and apparently the dual-quad setup was available although I've never even heard mention of one existing.

Yep, Tempest and Lemans are basically the same thing, even in Canada.

Q

T'anks!

Hey Quenton where can i check out the specs of the engine..cam, bore, horserpower, torque, ect.
I am trying to see if i can just rebuilt that engine for now. Or just sell both my engines wait and buy my 400

HP CI Trans Block Code CR Cam Heads Carb
250 326 M 925 8.6 441 9773345 2
280 326 M 945 10.5 441 9773394 4
250 326 A 960 8.6 441 9773345 2
280 326 A 971 10.5 441 9773394 4

1964 326...

so it would be 250 Hp for my two barrel carb.? And would it be 280 hp with a 4 barrel carburator? Thanks for the help Tom. You want to check out some pics that i took of the engine...it is my worst nightmare .

No, you have to go to the other heads for the higher CR and HP rating..

I wouldn't waste any serious time with the 326. All the work and money you will spend on it can be better invested in a motor that will have more currently available parts, and not require you to spend weeks looking for the right starter.

Now, if we were talking about an all-original 326 HO, I wouldn't be saying this. However, I have FIRST HAND experience of buying a 1964 Tempest with a 326, installing a new timing chain set, new cam and lifters, doing a complete valve job on the heads - including new guides, valves and springs and buying a new intake, carb and starter. The one and only time I drove the car was from my house to a junkyard where I got $65 for it, since I had the title. With no title, they would have turned me away.

Q

How true... and just as an FYI the standard 326 usually had #140 heads (lower compression) and the H.O. had #141 heads AND the 4V, hence the nicer HP rating...

Brett - 67 Drop Top 455!

True ... for a 1967 326!

But in 1964, the heads were those Banshee described (though I did find a number discrepancy) ... 9773345 for the 2V and 977339(5) for the 4V. (I also found a listing of a 285 HP 4V motor. Not sure which cam it used. May have been a 1965 motor?)
