Buick 350 V8 ?

You guys with the older Wags that have this engine, how do you like it? I found one with the stock 4 bbl manifold and was just wondering.

I think you'll find that the Buick 350 here has a bit of a cult following. (runs for cover)

But it's probably the best V8 Jeep ever put into a FSJ.

I have a 69 with the 350 in it and like it great. no smog equipment

I do not think JEEP had a 4 barrel on a Buick 350.

Right, only the cars got a 4V manifold.

The Buick 350 is a very good engine. I have some experience with Buick engines.

It had the lightest weight of all the GM small blocks (lighter than the AMC), so its power-to-weight ratio is excellent. It also had an extremely long stroke (3.85") that was larger than its bore, making it an undersquare engine. That stroke is more like what most big blocks sed. I cannot think of any other domestic OHV V8 of less than 400 cubic inches which had a longer stroke than the Buick 350, let alone was undersquare. Needless to say, the Buick 350 will develop monstrous low RPM torque. Even so, they make good high RPM power too. The 4bbl high compression 350 made 315 horsepower and 410 lb-ft of torque! That's more of either number than AMC's 360 ever did, and more on-par with AMC's 390.

Layout is very similar to the AMC V8 actually, especially in the timing cover area. They both use an aluminum timing cover which doubles as the oil pump, water pump housing, and mount for the distributor and fuel pump. All these components are in the same location on a Buick V8 as on an AMC V8, so if you know your way around an AMC V8 you will right at home on a Buick.

They have some peculiarities about building them that you have to be careful about.

One ting I have read up on is the aluminum timing cover/oil pump housing. The oil pump gears can sometimes wear the aluminum housing and decrease the oil pressure?

Same thing as an AMC V8. Virtually the same exact design with the exact same advantages and disadvantages.

In all reality though, the oil pump usually doesn't wear out until the rest of the engine is also worn out, so it's not like the oil pump is a weak link or anything like that. Also much like the AMC V8, they are not big makers of oil pressure. 10-15 PSI at 600 RPM idle is perfectly normal on a Buick. Ask most any old Buick mechanic about what oil pressure is needed and they'll usually just say, "Some". We put far too much emphasis on oil pressure, but it is actually not that great of an indicator of how well the engine is lubricating itself.

ok, so how hard would it be to find a flywheel for a manual tranny for this engine? I have a T176 or a NV3550 5 speed. or, are there other easily found options?

T56 -- why go for 5 speeds when you can have 6?

Love my '70 with the 350. Lots of power, no smog equipment (and better yet, smog exempt here in California). Mine doesn't seem to like 87 octane though so I run it on 89. On the highway I get 16+ mpg cruising which is great despite not overdrive. Hell, that's better than my 2.5L 4 banger Wrangler!

Loved the Buick 350 in my Gladiator! Had one first in front of a 3speed and then converted over to a t18. Wish I still had the truck.

Keep It!

I just finished rebuilding mine, semi warmed over for a bit more performance. It wasn't that bad and I've never touched an engine before. If you are looking to make crazy power, they will do it but it's more expensive. From a stock re-do point though they aren't that much more expensive than other engines. TA Performance is great, good people. I have yet to see how mine runs rebuilt, but it did a good job pushing my truck before, and that was with essentially no rings and no lift in the valves. Plus, the block is a "deep Y" and is very strong. The stock crank is pretty stout too. Buick just used good metals back then.
I'd say rebuild it, and keep the 4v.
Also, to answer your flywheel question, TA does sell new flywheels for the 350s.
