OK - anyone know what kind of car this came from? I was told it's from a '69, but didn't ask '69 what. Guess I should've. I don't see a WT for Firebirds, but I know WT is a Pontiac code. Thanks! Should I just look up the VIN on the block?

1968 400 HO MT code for GTO.

65-66 389
67-71 400
High horse power Goat engines

Then shows up again in 73 as a 455

www.teufert.net/pontiac/engcodes.htm

Chilton's shows a WT code for:
1967 V8-400 MT 4BBL
1970 V8-400 AT 2BBL
1971 V8-400 MT 3spd 4BBL
Cross reference that with your VIN /date codes and that will give you a better idea of what you have there. If you haven't looked already, here is a good site to visit while looking up various info for that 68 of yours. Enjoy that car, its a beauty. http://1968firebird.org/illustrated/illindex.html for more info

WT is an option for a 400 GTO & Tempest with manual trans, 4bbl. 10.75 comp. ratio 350hp.

Your Chilton's is wrong. So is Teufert (in this case).

1965/66, 389 MT GTO, not HO
1967/69, 400 MT GTO, not HO
1970/71, 400 MT GTO, GP and Firebird, not HO.
1973/74, 455 MT GTO & Grand Am, not HO

Thanks P.M.I. - I'm always leary of chilton's info and that's why I mentioned where the info came from.

I also wanted to point out that it was the book, and not you.

Even Teufert isn't 100% correct.

I've looked at many, MANY WT blocks in the last few years. I got to know them quite well.

Wow, thanks! I was so afraid someone was gonna tell me it was a Gutlass or something

Hey there now, a few Cutlass setups from 68-71 were awesome! My Dad had one that scared the whole neighborhood, right off the assembly line. I was very proud to be his Son, my Mom wanted to kill him for buying it!

Lets give those "Olds" engineers a little respect. I consider them (during that time) distant cousins to the FGF.

I had 2 '72 Cutlasses with the Rocket 350. You can't mistake those...gold engines with an oil filler pipe. They were torque monsters, as is the Pontiac.

Glad to hear you found a Pontiac under the hood, though!

Gotta love the cutlass/442! Agreed Nash & Vikki. I was looking for one when i stumbled upon my 68'
Nice to have a Pontiac under the hood though.

Yeah, Hemmings Muscle Car mag had a comparison of "big block" engines and what grabbed me was that the Olds engines have a longer stroke than Pontiacs. That surprised me.
