Aug 28, 2008 · The 326 subsequently became the optional V8 engine for Tempests, and later the Pontiac Firebird, through 1967. A higher-output version was offered, called the 326 HO (High Output). It had a four-barrel carb, dual exhausts, and higher compression, and was good for 280 hp (209 kW) for 1963-1965, and 285 hp (213 kW) for 1966 and the final year, 1967.

Dec 2, 2004 · Either you have to put an obsolete Pontiac tranny in it or cut off the chevy bellhousing and put a Pontiac bellhousing on it. Ultimately, you can make more power easier with the set-up they came with rather than dropping a heavier older engine in. I've heard of it being done but never actually seen it.

Aug 5, 2003 · Pontiac engines utilize the same block from the 326 all the way to the 455. So when someone says big block Pontiac, it isn't true. The only difference is the size of the journals in the block thus giving it the cubic inches nomenclature. Take a minute once and look at a 350, 400 and a 455 and you'll see the basic engine block for all of these cars.

Dec 16, 2006 · The '69 428 4 bolt main blocks are pretty stout. If used in a racing application the 4 bolt block is almost a "must have". The 428 2 bolt blocks are still good blocks for regular application but they are more common. The heads are what made the 428 into a brute so if you have some good heads on it then this motor can be a killer on the strip!

Jul 29, 2003 · This 437. You said it was a 455, but destroked. Does that mean it's Pontiac 455 with a 421/428 crank in it? Which cylinder heads do you have? (casting number is on the center exhaust ports) For a lot of great information on the Injun Engine (traditional Pontiac V8), get Jim Hand's book "How to Build Max-performance Pontiac V8s".

Feb 17, 2005 · Chevy 327 is a 4" bore, 3.25" stroke, and the 350 is 4" bore, 3.48" stroke. The Pontiac 326 is 3.8188" bore and 3.75" stroke, and 350 is 3.875" bore and 3.85" stroke. Also be careful comparing 400 Pontiac with 400 Chevy (small block). While the bore and stroke are very similar, that's where the similarity ends. Nothing interchanges.

Apr 5, 2006 · There is no 12" clutch for the Pontiac. In '69, only the 10.4 was in Firebirds. The 11" job came only on "big cars" with the 428 engine. The difference between the flywheels is strictly the bolt "circle". There are a couple of flywheel "weights". We've seen both 30 and 40 lb. versions from Pontiac. For the lighter car, the 30 lb. unit is desired.

Sep 30, 2003 · I also noticed that my running lights dont come on however they did. I only get the Service Vehicle Soon light when the car is in motion. I also have a Service Engine Soon as well. And i expirience jumping and a clunk noise when shifting from reverse to drive or vice versa. Any ideas???? My car is a 2001 Pontiac grand am gt 2 door 3.4l v6 with ...

Dec 16, 2012 · I have a Grand Am SE 2001 and recently, since I got home from college for break, there has been no noticeable heat, and the engine temperature gauge is reading below 100. I checked the heat of the input and output hoses near the firewall and both were warm (warmer than the air blowing in the car) but not hot to the touch and this was after 10 ...
