    350 Vortec VS. 5.3

    Hey everyone, Im thinking of getting a new truck and I am torn between a 96-98 vortec 350 truck or a early generation 5.3 vortec truck (99-02). How does the vortec 350 stack up to the 5.3??

    go with a 5.3, you wont regret it.

    Drive the two different trucks and you will notice a huge difference going from a 350 to a GEN III small engine.

    This is my opinion and im not bashing the 350s

    There is a huge difference. At the track, the 5.3 will run all over the 350. On the sled, the 5.3 will be run over by the 350.

    I was referring to my neighbors but ok.

    Couldn't pull said equipment with the 5.3?

    The 383 is a far cry from the 350.

    I don't know. We need stock equipment to test with.

    The 383 makes me think of the older diesels like the 7.3 or the 6.5 or the 12 valve. Sure they aren't all that fast, but nothing is really going to slow you down when you hook to it.

    Re: 350 Vortec VS. 5.3

    Honestly, both are great trucks. If you want power the new gen III motors def have a few less irritating things to fuss with than the vortec 350's...spider injectors for instance. Some of these things only matter if you're doing power mods though.

    I dropped a mild build vortec 350 in my brothers 98 scsb and that thing walked all over stockish 5.3's...crushed them...

    I think you can get a 96-98/99/00 obs vortec 305/350 truck @ a really good price leaving more for upgrades.
    If you go 99-02 nbs you'll pay more but will likely have a lower mileage truck.

    Pros & cons to both...what's your budget & what is your plan?

    that makes sense, but i feel like its whats around the motor that couldnt handle it. if we're gonna get technical here. that being said no gasser should pull a skid steer and 3 pallets of stone

    Maybe not a gas V8 which I like for it's performance unloaded and for light loads, they sound nice and are cheap to mod, but for work when you don't have a diesel you can always turn to a straight 6, a 225 slant, 300 or 292 is bulletproof and pulls like a diesel. a buddy of mine has an 84 F250 with the 300 that he put the EFI manifolds and 2.5" exhaust on, a 4bbl and 4.10's with the 5spd and that thing could uproot a tree if it could get traction. That truck amazes me, we towed 2 trees cut up in logs on a 20 foot flat trailer and it handled it like a champ, pulled up hills with ease never straining. The trailer we figured had to weigh over 8000 and it didn't sweat it at all, not bad for a 200k+ old truck.

    I'd rather have a diesel for stuff like that daily but you still have to give it credit, they can't beat a diesel but sure give a good fight. I like V8's as cruising motors, straight 6's are work motors. I think all the big 3 are stupid for killing the straight 6's, at least GM still makes the 4.2 and it'd make a much better base truck motor than the 4.3 which they should stick in the Trailblazer, leave that motor for the smaller trucks and SUV's and put the inline in the full sizers. If I had a truck with the 4.3 and it blew when I was towing or just because it was so old, i'd swap in a 4.2 and keep working. That'd really make a beast of a work truck, be like the good old 80's again when straight 6's ruled the half ton work truck world.

    Sorry, got off topic there but I had to put it out there, that's how I feel about it all whether anyone cares or not. I'd like to hear what everyone else thinks about it.

    "the big 3" didn't all kill the inline 6. you can still buy a brand new Dodge with an inline. they just took away its spark plugs and put a turbo on it.

    not sure what point in the 80s I6s were ruling the work truck world... i've probably seen less than 20 I6 trucks newer than 1980 that still had their inliner under hood... i owned 7 that lost them due to the more powerful small blocks.

    215 ft/lb vs 300+ ft/lb... its not hard to see which comes out on top.

    Re: 350 Vortec VS. 5.3

    If you start with the 5.3, you'll have all the parts (computer, brackets, etc.) you need when it's time to upgrade to a 6.2L or larger. I like to tinker, I'd find a truck with a blown 5.3 and score a 6.0L with an iron block and give 'er hell!

    Re: 350 Vortec VS. 5.3

    My gasser will pull a skid steer and 3 pallets of stone NO PROBLEM. I pull 1 some times 2 skidsteers on my 30 Foot Gooseneck trailer once or twice a week. Not small skids either T-300 Track bobcats. Thats off topic not no gasser should pull it. LOL LOL LOL


    All that a side for a second. Not knocking the 5.3L not my point. But until someone puts 560,000 miles on a 5.3L or 6.0L in less then 10 years without taking the valve covers or timing cover off I'm still with the GEN 1 Small blocks and big blocks. That truck which was mine 2 trucks ago is still on the road with 610,000 last time I saw it. Since my 1500 ext. cab half ton I have had two vortec big block powered CCLB duallys. I have over 190K on my sig pictured right now. But I do a lot of driving every week.
