Rebuilt vs Remanufactured

[RADIOACTIVE_TOOL_SHED___]

I have a 93" 4.0 with 343k miles with low compression on cylinder #3 (rough idle issue) I'm looking at either having the engine that's in it rebuilt or getting a remanufactured engine from power train products and putting in it, what are yalls thoughts on reman vs rebuilt engines? I thought remans had everything that could possibly wear replaced? Some had said yeah others say it's the same thing as a rebuild but it's done in a factory so it's more professional I don't care where it's done I just want the longest lasting motor possible. If I have it rebuilt what parts should I have replaced regardless of wear? And how much would it cost to have it rebuilt?

remans are good in that theyre "standardized" they replace most everything is my understanding.

rebuilds change whats worn/what you want them to

rebuilds are more customizable, but like many things its the skill of the rebuilder. a great rebuilder can build you probably a better motor than a reman. a bad rebuilder, well you get the idea. a good rebuilder will do more than a reman if they put all new parts, essentially remanufacturing it themselves and they can remedy known issues like the heads on your ohv for example. good part about PP is that they warranty and will reimburse for labor at many places, vs its only warrantied at the rebuilder you take it to.
jmo best tebuild is one you yourself do.

good luck!

for a rebuild imo with ohv main thing is heads, bottom is solid imo

one thing about a rebuild is you build a rep with the shop and as long as theyre trustowrthy you know everything thats been done to it. ive seen in some cases sucky remans that used old parts, potentially from a good parts unit and then just replacing stuff like the clutches (tranny) but some orher trans parts were dated okder than the case, which means they used maybe a parts unit

tldr: good rebuilder >reman but if no good guy nearby then reman is more stabdardized than a bad rebuilder.

If I go for a rebuild I want new cylinder heads oil pump timing set piston rings all new bearings all new gaskets rocker arms push rods should I have the camshaft replaced? And crankshaft?

I spent a significant amount of time researching and pricing out the best engine for my money. I’m not a rich man and had a budget of about $2800 for a long block, and could go a little higher if it required less work to break down and ship it. To have another mechanic do all of the work was around $5k.
I found that many places used the term remanufactured and rebuilt interchangeably. As noted above it seems like local shops call it a rebuild and online shops (which are local shops to the people near them) usually called them remans. Most offer a decent warranty and new items like oil pump and gaskets and a few other items and the prices hovered around ~$2k. The problem I had was that the shipping was a substantial portion of my budget, and I wanted to see where I was sending my engine and what the place was all about. It’s nice to be able to show up and ***** at people if their work is lacking. I found a shop that was sort of close by and had good reviews from the locals (and some non locals) and answered their phone and was willing to chat. He knew exactly what engine I was talking about and quoted me $1,700 or something close to that for a long block. You might be surprised by the prices some local shops charge for a good rebuild and you save some money by just crating it and bringing it over. Anyway, that was my experience

I trust a crate long block WAY more then a local rebuild
Why?
Because the crate engine remanufactures do this all day every day, which is why they offer a reman engine
Power train products is good!!

A rebuild by a local shop is USUALLY a crapshoot and can end badly costing much $$$$
