What do you get when it’s remanufactured? Is it decked? Line honed? Honed on a new machine wising a profilometer to get the finish correct?
Today, dollar for dollar, is the 318 faster than the 340 ???

IMHO, a waste of money on a well seasoned block that measures out OK.
But it your money to spend to keep from being called a cheapskate.
Some like Budweiser Beer. I would not use it to wash mud off my boots. Basically "Opinions are like ......" My opinions are not always right but maybe some of yours are not too.
I think all those prices for machine work are not only in the ball park but pretty darn reasonable. Even so, on my current slant six build, I will end up having done almost all of that, but of course have to spread it our over time. It costs a lot to do one dead right and not a dirt road build.
Right. It's much like buying an engine kit.....which I constantly preach against.....and people run out and do it anyway. You're at someone else's mercy.
Just like a reman. Who did the work? What did they do? Trust me. I've been behind that parts counter and seen first hand how upper management does every single thing they can to get out of engine warranties. Makes my stomach turn. That's why I am constantly telling people to learn to assemble one yourself. Find a quality machine shop. Yes, it'll cost more. But it'll cost more than that to do a cheap one twice.
If something measures good and in spec, I run it. But I can almost guarantee you are not going to find any Chrysler V8 or slant 6 with a deck surface in spec.
Just to kinda slide/make a point the mopar crate engines used new production line engines. Then when they quit producing the factory engines they started using remans. And made pretty good reliable 380hp engines.
And not just mopar done that
The only thing I would be worried about is the head work on the guides.
The thing alot of people are leaving out is that forged pistons are hard on cylinder bores and have alot shorter life span. $3000 can be done reliably and make pretty good hp. Factory has been doing it for years

Me ^^^^ that's how I roll. For a basic 350 horsepower motor people think you got to have each piston fitted to it's own cylinder, and all the blah blah blah. In other words, in 1968 if you bought a new '68 cuda 340, you should take it off the show room floor and immediately disassemble it. Why ?? Because from the factory......
- batch-ran cam wasn't degreed
- batch ran pistons were thrown into any hole
- green blocks weren't always even
- scabs and snags all over the castings
- batch-run timing chains were used.
- heads varied in CC's

May not be the best but I know a few cars that have a Jasper's engine.
The Jasper Process: Engines
3 YEAR/100,000 MILE WARRANTY
JASPER® can offer this beefy warranty on our remanufactured gas engines because every one of them goes through our extensive "Do It Right" process that ensures worry-free operation. Click here for a full warranty disclosure. Our optional Premium Service Plan provides allowances for such items as towing, car rental, fluids and premium labor should a problem arise. Click here for details and limitations.
THOROUGH CLEANING
Every JASPER reman gas engine is completely disassembled. Blocks, heads, connecting rods, crankshafts and camshafts are thoroughly cleaned through a variety of processes to remove contaminants that can result in premature wear to internal engine components and early engine failure.
CRANKSHAFTS
Crankshafts are precision machined to exact tolerances with no odd size bearings or journals. Thrust surfaces (domestic engines) are micro-polished to provide precise surface finishes for smooth engine operation and reduced thrust bearing wear. Every journal is inspected and measured with critical accuracy. After machining, oil holes are chamfered to improve lubrication and every journal polished to a smooth finish for long bearing life. Crankshafts are thoroughly cleaned with special emphasis to flushing and brushing out oil passages to remove any contaminants.
CAMSHAFTS
Camshafts are inspected for wear, dimensional accuracy and gauged for straightness. Camshaft lobes are carefully machined to correct specifications. Each shaft is Parco-Lubricated to improve lubricant adhesion, especially during break-in. Any camshaft not meeting JASPER's exact specifications is replaced.
CYLINDERS
Cylinders are bored and honed to exact specifications. Most gas engines are torque plate honed - a process we learned from our involvement in NASCAR - that eliminates cylinder distortion after the head is bolted and torqued to the block. This process eliminates a major cause of engine blow-by. Blocks are carefully inspected for cracks and flaws through procedures such as magnetic particle inspection. Cylinder finish and size are closely monitored to industry surface finish standards as well as for accuracy and consistency. This assures smooth piston travel and engine performance. JASPER guarantees no odd size cylinders. The block to head mating surface is closely inspected and resurfaced as required to provide the correct surface finish for today's gasket materials.
CONNECTING RODS
Connecting rods are machined and gauged to within a half a thousandth for improved operation, especially in today's engines. Rods are carefully machined to avoid taper and to the standard diameter of original equipment. All rods are checked for bend and twist to assure smooth operation.
HEADS
Heads are carefully inspected for cracks and flaws through procedures such as magnetic particle inspection. Every head is resurfaced to exact dimensional tolerances and the surface finish is carefully monitored for proper sealing with the block. Valve seats and guides are machined to exact specifications or replaced to assure correct valve alignment and seating and optimum engine performance.
ASSEMBLY
Every gas engine is precisely assembled by trained JASPER builders. Attention to such details as a final wash of new and machined parts and pre-lubricated camshafts, pistons, and crankshaft journals assures a clean, smooth running engine that performs to your expectations.
TESTING
JASPER live tests every popular complete domestic and import reman engine with recorded inspections of temperatures, oil pressure, vacuum and compression. Engines are black-light inspected to assure there are no oil leaks. JASPER's testing is one of the many ways we assure your satisfaction.
QUALITY CONTROL
Consistent quality is maintained through a continuous training program of technicians, many of whom are ASE certified, backed with statistical process control. Technicians are also JASPER certified to specific engines and job functions. Quality audits of all areas of the engine are scrutinized for cleanliness, surface finish quality, lubrication, clearance and wear patterns.
WARRANTY
Install JASPER with confidence. Every JASPER remanufactured engine is backed by a nationwide warranty. Complete engines for passenger cars and light duty trucks receive a 3 year/100,000 mile (whichever occurs first) parts and labor warranty. (Ambulance, off-highway vehicles, package delivery, police, snow removal, taxi, tow truck, or any vehicle over 1 ton, 18 months or 100,000 miles, whichever occurs first.) A technical hotline (1-800-827-7455) and 24 hour 7 day emergency warranty information are also available. A full warranty disclosure is available on this website or upon request.

Sales and marketing hype. Unless you're doing business with a local shop, you have no way to verify but to tear down your Jasper or whatever remen engine.
8- $10,000 for a quality built high performance engine carb to pan. $5000 more if your going bullet proof with premium parts and cylinder heads.
700 if ya just want to have fun
Another problem when most people get all of this balancing done is they just do the rotating assembly and never touch the flywheel or flex plate and converter and harmonic balancer when in reality everything connected to the crank needs to be balanced together. Or that balancing money was more than likely a total waste.
Unless a person is making a serious effort towards the nationals there is no reason to get tied up in $10,000 because your forged pistons are going to where the block out in around maybe 30,000 mile being optimistic.
Depends on what level of performance/goals you are building for
The good news is 318’s and 340's have excellent rod/stroke ratios

Your “well seasoned” block won’t have straight bores, decks or main line. I outlined what I consider to be the bare minimum for machine work to do a rebuild on a core. As RRR pointed out, the prices weren’t even unrealistic or unreasonable. You can do it cheaper but what’s the gain except you have a few more dollars in your pocket? And as the numbers point out, and as I said from the beginning the 3k rebuild number is unrealistic and unreasonable. Doesn’t matter what engine you start with.

i got one of there /6's on a stand now less that 3,000 miles with 2 smoked bearings and a wrist pin coming out of a piston!!! i wasn't original buyer so no warranty!
There is a place, time, and a reason for high dollar builds... of 8k - 20k. For the purpose of this thread, 3k is a generous budget. A re-ring kit with new gaskets and fresh heads can be a reliable engine for years and years and offer performance. Nobody gonna tell me different, been running this way for about 35 yrs. Again, 6 years of beating on a 500 - now 750 dollar with dual quad 318 and 5 years of beating on a "now 1450" with aluminum heads 360.
- again, it took me all of a whoppin 498 documented dollars with a 318 to run with a stock 340. I'll take the free 318 vs the collector $$$ 340 on a 3k budget, starting from scratch at fair market prices.

That’s not true. A forged piston isn’t harder on cylinder walls. Their life span is far better than a cast equivalent. Plus you get the benefit of a far, far better ring pack. That in and of itself makes more power, seals better and will live far longer than the thick rings that come on cheap cast and KB pistons. Again, it becomes penny wise, pound foolish. And if we say let’s do your 3k reman, you are stuck with the cam they pick, unless they have options. And on top of that, you didn’t get the China knock off heads that 318WR said he could do for his 3k build.

How is 5000-6000 dollars an expensive build in today’s money? If you are building things today like you did 35 years ago that is a sad thing.
I'm getting old, lol If I'm building an engine, it will be a minimum 700 HP stroked big block.
It's still less than my wife's Durango RT. lol

I’m going through this section by section. It says they reuse camshafts. I don’t care if it’s an OE roller cam, it comes in as a core and at a minimum it needs to be reground.
They only surface a block of they think it requires it. Every block needs to be surfaced.
You still get factory connecting rods. That makes no sense when aftermarket rods are so cheap.
I have to read their warranty to see what it really is. Just the fact that they might reuse a cam, only surface a block if they think it needs it and using factory rods is a turn off for me.
Hmm here we go again lol
What silicon content forged pistons are you running? What are the clearance number's from pistons to cylinder? What cranking compression? Personally I have never seen a forged piston motor last to 100,000 miles no matter what. Some hyper's yeah and cast yeah but not forged. All of the forged pistons I have ever seen run loose clearances to allow for the expanding and then they beat on the cylinder walls and wear out faster
the older i get, the more open highway i want in front of my grill...... classic car grill that would be...

some folks just dont have that much much money in there hole car! to have to spend that much on just the engine would flat run alot outta the hobby all together!! some folks can live happy with what you would consider compromised junk builds and some cant! if i could afford id build erry thing i got along your guide line but in reality i gotta live with in my budget! i know the difference and understand the results of building ether end of the spectrum! telling us we gotta build 15,000 dollar engine for rusted out daily beater or we wrong, might as well just call us plan whitetrash a be done with it....DWB
1650 miles away from home.... Sedona, Az, me and the misses.... best times in a classic,, on the old mother road... route 66.
I was thinking of finding a 68 Fury VIP 2 door like my dad had in the 70's and putting a 700 HP stroker in it.
Highway gears in the highway star and take on some vetts, stangs, maro's and challengers and eat them up. lol
