    Last question fo the day...I have a pos 2 bbl 350 in my 78 k5. I want it out and new engine in it. I do not want carbueration. I was told Chevrolet makes a 383 hipo replacement that will bolt right in and it includes fuel injection....I was also told that all i need with the engine is some type of computer harness and a computerwith it.....Is this true or is there more to it than that...and do you fellas have any reccomendations on this??? I was planning to get my new engine straight from GM and have it installed at the dealership....

    GM sells a new 383, but it requires a carb. However, they also sell a fuel injected 350. Check out this bad boy:

    I know you said no carburetion, but my god man! You may reconsider if you put on a 4 barrel! Kind of kidding, but that 2 barrel must really suck. Never driven a truck with one, I can imagine its not a fun ride.

    Why insist on counting when the ring gear has the tooth counts stamped in?

    Glad to help! BTW, the 383 can be fuel injected, GM just doesn't sell them that way. You have to start getting into customizing things to use fuel injection on it.

    I can definitely understand that. Fuel injection is hard to beat, thats for sure. I'm sure some of you that live in colder climates have a problem starting your vehicles.

    ok i got one question,,why have a dealer install it ? why not save some cash and get a local shop to install the engine, hell,,maybe even someone on here that's close would do it for a few hundred,,i know i would.and if you want,,all you need to do is buy your new long block,,and spend $1500.00 and you can bolt on a holley pro-jection system or and edelbrock or something like that. and it IS NOT hard to do, yes they give you the computer and everything and it's not a nightmare to do yourself. just like anything else on your rig, do it right and watch what your doing.
    are you wanting to get a new crate motor or are you wanting to just get a rebuilt one ? i can't see you spending more than $4000 on a VERY nice engine and injection system,,labor included !

    oh yeah,,fill out your profile so we know what you have,where you are and whut color underwear you've got on ,,lol

    If you can recomend anyone in Charlotte NC besides a dealer I would be grateful. I hope that it does not run more than 4000.00 but 350 engine listed by Harry in a previous post was 4700.00 not including labor.... I do not mind putting a rebuilt engine in it.

    If you want to spend a lot less money and still have a strong engine, check out this bad boy!

    Doesn't come with fuel injection, but that's a heck of an engine for the price!

    you got a pep boy's or auto zone or napa or western auto anywhere near you ? they all have replacement motors for around $1500 with yours for a core. they are actually good motors,,jasper makes the ones for pep boy's,,i dunno if they do anyone else's or not. plus they have a 12 month warranty on them to.there's a lot of guy's on here from NC i believe,,put up a post about finding a shop or someone doing it them selves for you,,it will save a lot of cash on your part.a motor shouldn't really cost more than $500 to pull and replace, i'd do it for half that just because i like werking on stuff. ask around,,someone might just be able to hook you up with a shop of their own or a good local one to go to.

    Note: This engine is not intended for use in fuel injected applications. For high performance fuel injection engines, please see our Custom Crate Engine selection.
    i dunno why they would put that on there ? the motor doesn't know if it's being injected or not, as long as it get's fuel,and i think the projection or the edelbrock system would feed enough fuel to that thing ?

    I think it's just that those engines won't work with a stock TBI system. The stock 350 TBI is calibrated to deal with a 200 HP engine. To make 330 HP, you have to move a LOT more air and fuel through the engine. [​IMG] They don't provide any details on the page for their "high performance fuel injection engines", but I'm guessing that they would include bigger injectors, or possibly even a complete throttle body and injectors from a stock TBI 454, along with a custom chip to make it all work together properly.

    Well here's my 2 cents worth
    Here's two engines I recomend If you are wanting to go with a TBI system
    <a target="_blank" href=http://www.sdpc2000.com/cart.asp?action=catalog_start&amp;catid=1577> SDP TBI Performance Engines</a>
    Both of these engines have cam profiles that will go very well with a computer controlled TBI. . The 300 HP engine should run on the stock chip.
    I would then match one of these engines up with a TBI system from these guys:

    My carb doesn't give me grief. It fires up with one pump and doesnt stall out. Once you start talking Ramjet and dealer installed, the $$$ really start adding up. Of course I am from the KISS school (keep it simple stupid) and like to have stuff that I can get working with the BFH.
