    Replacing Blown Motor, 5.7... suggestions?

    Super informative, thanks for taking the time to write. I'm going with a 383 if I end up needing serious work on the motor I have. Just makes sense. Now off to do some research on exactly which part from what company I need. Wish me luck!

    Wouldn't increasing the size make anyone feel better? Lol if you read the entire post, im sure most of those questions you have will be answered. I'm not a mechanic, but not an idiot. I have ran through all the thoughts of drivetrain and what a bigger motor might do. Hell if the driveline breaks...

    Thats why I decided to do this myself in the first place, you'll take more pride in the rig you're driving, and no one will work on your truck like you. Yeah I might mess some things up... but... I'm willing to learn and have been taking all your suggestions in and trying to figure what fits...

    Seems doable. There's a machine shop near me I'm gonna call them on Monday and see what they say. Would love a 383.

    I'll do some research. Found a 2 bolt main crate 5.7 for around 1900. Ships in 4 months tho... damnit.

    IF I get a crate, whats the deal with 2 bolt or 4 bolt main? I have a 5.7 L31 and looking for something that will bolt right up to what I already have. The 383 is out of my price range. Sorry for stupid questions... all new to me.

    Already mentioned the knocking. I'm good with tough love, like I said I'm way out of my elements here, hence the post and request for suggestions. No bore scope. I could probably purchase one. Should do that. But again, not a mechanic and there aren't many around that do good work in my area...

    Replacing Blown Motor, 5.7... suggestions?

    Well, that nut was tightened down by yours truly so I will back it off for sure, but it never ran with it that tight. I removed that nut to take the rod out and inspect and the spring did not release at all. It is stuck in that position. I know nothing of lifters or springs so thats why I...

    No oil pressure issues, although, these oil pressure gauges are crap I've been told. BAD knock, have to keep on the gas pedal just to get it on and off the trailer. Current status is I have drained the oil, the coolant, and removed wiring harness and both valve covers. Other side of engine looks...

    Replacing Blown Motor, 5.7... suggestions?

    It is jammed in place. I removed the nut that holds the lifting rod and it didn't budge. Engine sounded terrible, with a loud knock. I don't have a compression tester and never even heard of a leak down test (novice here)... sorry guys I wish I could say I was more mechanically inclined but I'm not.

    Replacing Blown Motor, 5.7... suggestions?

    It started with a cylinder 3 misfire code. Accelerating up a hill started a heavy knocking and when I pulled over it completely died. Trailered back to the house, it won't stay running under its own power. Sounds terrible. So I removed the valve cover and the only thing I could see thus far was...

    Replacing Blown Motor, 5.7... suggestions?

    Yeah I do agree, I am currently taking everything apart and inspecting the engine. My problem is, if I'm breaking everything down, why wouldn't I rebuild it, especially after 300k... so do I dump money into this engine? Or find a replacement. And my luck (which is less than ideal) is that its...

    Replacing Blown Motor, 5.7... suggestions?

    The 383 is appealing for sure. Nothing but good things about it, but I'm pretty sure my heads will at least need to be serviced etc before installing. So... anywhere I can get the full 383 with heads and 395 cam as a package? Ditch all my old seasoned parts...?

    Replacing Blown Motor, 5.7... suggestions?

    Pretty sure a valve is stuck or broken, engine had over 300k on it. So its either rebuild this one ( out of my elements ) or buy a reman or new engine.... when I pulled the valve cover, cylinder 3 had a rod completely loose and the lifter for that rod was loose as well. The others are all...

    Replacing Blown Motor, 5.7... suggestions?

    Well, I don't know much about engine specs, doing this on my own. I would love to get a better, more powerful engine than the 5.7 I have. Not sure what is involved with transferring the top end over as you said. If I were to get a HT383 and 395 cam, do I just unbolt my tbi and bolt it into the...

    New to GMT400 from Oregon

    I had a 91 that wouldn't pass when I lived in Portland, all I did was retard the timing and it passed with flying colors. After I left, pulled over and advanced it. This won't fix anything but it will get it to pass, if you can do that on your truck. Not sure if the 94 has the same distributor...

    Replacing Blown Motor, 5.7... suggestions?

    Thought a lot about the LS swap. But I really want the truck back on the road. I'm looking hard at crate motors and wondering if anyone has a suggestion on exactly what I can put in my 98 1500 that will replace my 5.7 without too much hassle. I can do the wrenching, but I am not a mechanic nor...

    Wiring info needed

    If you go to LMCtruck.com you can download a full diagram of the entire vehicle and the blowups are super easy to view. You can also order a catalog (free) for your blazer and it will have the diagrams in it. It's helped me countless times. I hope this helps ya.

    98 3rd door seat belt question!

    New here, I have a 98 with the 3rd door and the seat belt needs to be replaced, can any seat belt from an OBS go in it? Having a hell of a time finding one specifically for that door. LMC wants $300 for the front set... Trying to keep the cost down. Thanks for your input!
