    list of good GM engines

    Why is everyone so hard on the 305 its not a engine for racing but there good little engine for a every day driver mines got 156k on it and yes im in the process of building a 383 stroker for the Monte but my little 305 still runs good and I really cant complain about it other then the lack of hp.

    it's big problem is the small bores and small valves (hard to breathe). it's not a bad engine, but considering there are so many other SBC's to choose from, well, the 305 would be the last on my list. besides, for the most part they were low HP smog engines.

    I don't think there's anything wrong with the 5.0L HO V-8 in the late model Iroc-Zs and GTAs. I don't know much about any other 305cid V-8 you might be referring to.

    there were two late 80's HO 305 engines - the CCC Q-jet L69 and i think that engine actually had bigger valves than the regular 305 LG4. the LB9 TPI 305 was the best 305 IMO for obvious reasons (a baby TPI L98). i think that was the last HO 305 made, i think the last 305 of all was the TBI L03 Caprice engine in the early '90s but i could be wrong. oh yeah, the 305 wouldn't be the worst on my list of SBC engines; i would reserve 'the worst' for the 265, 267, and 262 versions of the SBC.

    if I had to pick some good engines, I'd say the 2.0L 4 cyl is a good engine for a poor college student, or an 85 year old woman. The 3.1 in my 89 olds was a bit testy, but it ran to 210xxx miles with negligable care and work, I have a 3100 in my 94 cutty, and its goddammed fantastic, smooth, powerful, efficient, a true winner all around. 68 olds 455, sweet, not a racer in the cutlass convertable (frame too big) but its sweet for picking up bar skanks. New 350 vortec, sweet, L67 in the olds intrigue, thats a nice marriage. (Come to think of it, there are a lot of Olds in my family.)

    As for the 3.3, its reliable, but not a fun drive.

    Shitty engines: 1500cc, carburated inline four (came in an 88 Nova) It was a lawn mower with go kart wheels.

    L36, laundry list of problems. Seen a 99 intrigue in 4 times for, ignition, exhaust, water ump, and alternator.

    Whatever they threw into the 97+ sunfires. Ewww. Thats just wrong.

    the 1993 5.7L (350) in our Chevy Suburban is my fav. engine, we get 25MPG on the highway with that baby, and it's bone stock, with like 110km/s on it, purrs like a kitten (though, idles low, and my dad refuses to let me fix it... he's out of town though, so I'll probably do that sometime tomorrow, but yeah.... it keeps up pretty decently to a Z, and for some reason, when I drive the Sub, I can out manuvre at late 70s T/A,

    The L67 is the Supercharged 3800 Series II, I don't think that engine ever came into the Olds Intrigue, but the naturally aspirated 3800 Series II did.

    Funny, you mention the L36 for having problems, that's probably GMs most bulletproof V-6 engine of the mid-90s to present.

    The problems that he listed are all peripheral. If peripheral problems like water pumps, ignition, and alternators makes for a bad engine, then that makes my 2.8 and 3.1's the worst engines EVER.

    IMO, I don't count peripheral problems, although my Gen III V8 has never even had a peripheral problem!

    L67 could be ordered for the intrigue for the first year and a half of production, or that is the best of my knowledge on the matter. And peripheral problems aside, Gen 2 engines are amazing. Although, come to think of it, my 89 went through three alternators in about 16 months.

    Umm... no. You're maybe confused with the L36.
    The Supercharged 3.8L Series II [L67] motor was never available in the Intrigue.

    i beat a '00 Intrigue 3.5 DOHC by a nose with my n/a 3.1 MPFI V6 up to 50mph @ 205,000 miles. it probably would have past me at around 55mph, but still - i wasn't impressed with that engine - i thought that car would waste me.

    Yeah, when I mention "best" engines, I mean strictly the engine itself. To me, the qualifications for an excellent engine are:

    -High Reliability
    -Easy Maintenance
    -Decent Fuel Economy
    -High HP/Torque Output

    My first W-Body had a 3.1 MPFI and it had many peripheral problems. I think the only part of the engine that died out was a fuel injector or two.
