[GOPAPA]

I will stop here with this info about what I want ,,and learn from some of you more about what I should look for or do or not do ... I will putting it in my 83 K10 Chevy Truck. I will appreciate pros and cons

I would consider a 383 Stroker too

[Rickysnickers]

Larry, what is your budget? That's one of the biggest pieces of the puzzle. I have a Blueprint Engines engine (that doesn't sound right) in my truck. It's been great and I have had no issues with it. Lots to look at here, https://blueprintengines.com/collect...ock+Compatible

Another for Blue Print . Haven’t been driving it long but as of 450 miles I’m happy with it

Not to be rude but that's far from enough time to recommend a builder.

GOPAPA- You could buy a GM HT383. Its just a 383 version of the vortec 350, strait from GM.

Just hearing of all the engines that don’t make it through the break in some right here on this forum iI think at 450 miles I can recommend them

Not for nothing but the HT383 puts out 323 hp?

Aint that the truth. My dad has a pretty new blueprint 383 and he is really happy with it. The GM 383 HT just needs a better cam to wake the eff up.

Yeah its super low. But its literally a vortec 350 stroked with a still puny cam like he was asking for.

Personally, I don't get the love for crate engines. Rebuilding is so much fun. I like picking parts myself.

Thx guys ..Blue Print sounds good ..I was wanting to stay under $5k and some of these are Rick ,, of course there is tax and shipping and then cost to pull my old motor and install the new one ..around $4k would be better,,
I want a motor with HP just a litle over 300 as that will pull my small Travel Trailer .
What all do you get for a complete engine ? I want vortex and 4 bolt main and could use my edelbrock 600 that is like new that can bring the price down??

No shipping if you order through Summit . They came with a box truck with a lift gate .

I have some metal flakes in my oil filter when changing it ,,this is aft erI had the cam lashed with my solid rockers that it was found ,,and coming home it was a hot day but going 55 mph my oil guage was tapped out at 80 and then some.. can one figure that for every 1000 RPM's a 10-20 psi ? in these old chevies 350's

That looks like the way Buicks run, varying pressure with RPM. That looks like good oil pressure to me, mine almost pegs the gauge hot on the freeway, and about 30 psi at idle. It depends on what bypass spring is in the oil pump.

The 350 that was in my 72 would peg the oil pressure gage too . I’m going to reseal the motor and put it into the 68 Anniversary truck . Ran well just leaks oil everywhere .

I built my own. I started with a 5.7 block from a 98 1 ton - 4 bolt main and drilled for a mechanical fuel pump. I had it bored .030 over, new pistons and cam, had the heads modified for the springs, and I was into it about $2,400 for parts and machine work. That was in 2020, so I'm sure it would be more today. It helped that I have a friend who owns a machine shop, so I got parts at his cost.

I ended up with around 330 HP and 400 lb-ft of torque. And it makes the torque nice and low.

Thanks guys ,, I am undecided on what I will do ,, I appreciate all the information I ask for..

You don't need to be hung up on a 4 bolt main block for what it sounds like you want to do. I will also give another thumbs up for blue print. I have a 427SBC from them that came as long block, their heads accept regular and vortec style intakes, I've used both and both seal. I've also used a SBF302 and rebuilder series 350's, all have been great. They also have a warranty and they are really helpful over the phone.

Could you source a block and work with a machine shop to build you an engine, sure. Might it be cheaper, maybe, might also have to wait for parts, find a block and hope it's good, etc etc. For $4650 you get a virgin block, a warranty, roller cam, throw your carb, intake, and distributor in and enjoy your engine, plus it's in stock ready to ship from summit. https://blueprintengines.com/collect...ec2dbf43&_ss=c

That's a very decent price for a good engine. If I were doing mine today I'd probably go that way.

[GOPAPA]

You know what.. I read on here that some of you have 350 engines that run at 80 lbs preasure and it is seems ok for the motor to do that .. I could with (( help)) change out the spring to a different one and get a lower PSI ,, as for changing out the motor ,,I would need lots of help and after reading and looking at summit and others , ,the motor would run me 5 plus thousand dollars plus Tax which is 6% guessing the cost would be over 7 k

I think i need to fix what I have as I did not know the cost of new , thanks again for the help ,,I am backing off a new motor as my truck is not worth it and my age tells me to not do so.. hope you understand my thoughts on this and did not want you all to think I was dead set on a new motor..

[truckster]

I re-read through the posts. It seems your concerns are metal flakes in the oil filter and high oil pressure. I would recommend taking an oil sample to a heavy equipment dealer near you (call first). Most can do an oil analysis and give you a good idea of the condition of your engine.

Secondly, how confident are you that your oil pressure gauge is accurate? I would use an oil pressure test kit to verify your pressure before you make any changes. They're cheap on Amazon, or you might be able to get a loaner at an auto parts store.

If the oil analysis is good and the pressure really is high, you can just replace the oil pump with a standard displacement unit. I like Melling, but there are other good ones, too.

This is very good advice. Any equipment dealer should have oil analysis kits, typically runs about $30 for the kit and test. Deere, Cat, Kubota, etc all should be able to help out, heavy duty truck shops should also have the kits, I think you can even get them on Amazon. An oil pressure/Auto trans pressure test kit should be readily available through the loaner tools at your local chain store, if not, again they are cheap or another mechanical gauge to verify. Years ago we had a 2000's G van that would literally blow the oil filter off as soon as it fired up. Dropped the pan, pulled the oil pump and sure enough the relief valve was stuck. Swapped a new pump in and problem solved.

Whatever you decide to do, I'm just glad to hear you're keeping the good ol' SquareBody going!

[Rickysnickers]

Larry, I got your PM. I can probably help you. Before committing to changing out anything, do as the others have suggested and have the oil analyzed. I'd as change the oil in the engine, again if you already have done it, and cut the oil filter apart. Look through the pleats in the filter and see if it has any metal shards or flakes in it.

Thx Rick , When I had the lash set on my rockers / cam there was a few little pieces of shiny metal flakes around the rockers,, figured it could of been from an over haul the engine had ,so I changed the oil cut in to the filter and found very few metal flakes.. did not see any in the oil ..I have run some 3 thousand miles on it since buying it ,, the owner of the truck before me had the truck over hauled some 25 thousand miles ago .. ..I called the place in Portland Oregon and the owner of the place verified the over haul ,Yes ,,I am going to look for a place here that does the oil check ( you know of any to recomemd ?)and then go from there to checking the guage to the pump .. I guess in that order.

I don't know of any Larry, that are local. However, try the John Deere tractor shop in Nampa, as a start, and see if they do it or can refer you to a local place that can check out the oil.

[GOPAPA]

I have found a machanic that builds race car motors to help me find out about the small metal flakes in my engine ,,He is going to run a camera down inside the motor and see what it looks like for flakes .. then he is going to check my oil pressure guage out to see if it is accurate ..then after that I can make my mind up with what next I want to do .

Where can I find a new Oil Pressure guage to fit in my dash for this 83 Chevy truck ? If I need it ?
