I want to build a Engine

[Win]

Do those shortblocks come bored?

Our economy short blocks are just the ticket for that budget build! Our remanufactured short blocks start as good cores that are dissassembled, then placed in state-of-the-art, environmentally safe burners, followed by steel shot blasting to clean. The blocks are magnifluxed, inspected for cracks, bored and precision honed to manufacturer's specifications. They are then fitted with new, .030"-.060" over cast aluminum pistons and cast rings*. 50-oz. cranks are precision ground to recommended specifications, and micro-polished. Short blocks do not include cam or timing chain. Each economy remanufactured shortblock includes a 90-day, 4,000 mile limited warranty**.

*Cast aluminum pistons and cast iron rings are recommended for naturally aspirated combinations only. Not recommended for superchargers, turbos, or nitrous. Always check piston-to-valve clearance when installing aftermarket performance heads or cams.

**Some conditions apply. This is a replacement warranty only. Labor and shipping costs not included in warranty. Overheating, abuse, or lack of regular maintenance may void warranty.

If you can't afford $700, you can't afford to rebuild a motor. Especially a 331 with ported heads/intake.

QFT! If you think $700 is too much, you shouldn't be modding cars man, sorry! One thing you HAVE to come to peace with when modding a car is that you will never see that money again. I got over that and haven't regretted a penny I have spent on mine.

Dude I never said that. Im just saying that on my Teenager-ass budget, I was trying to find something cheaper. Damn you guys rub it in like no other. I didn't say I couldn't do 700, But more that I DIDN'T want to. Hopefully if my teacher comes back from his vacation he can show me how to port heads n stuff. Trust me I know about spendin money on the car. If I could I would spend all my money on my car since I dont have any living expenses lmao.

Me and Rice are both 17, we know alllll about teenager budgets.

there is absolutely nothing wrong with buying a junkyard engine and rebuilding it. to an extent it doesnt really matter what happend to it before you got it. thats why you are rebuilding it. depending on the condition of the engine when you get it, you can possibly get away with new bearings and just boring the cylinders and replacing the pistons. ive even seen just honing the cylinders again to get the cross hatch and just replacing the rings and bearings. I would preplace the rod bolts while i was at it just for extra measure but its not technically necessary. if it were me i would disassemble the engine and take it to a machine shop and have them check the crank and block out just for peace of mind. to build a decent street engine, its really not difficult. all you need is a list of specs of bearing clearances, ring gaps, and torque specs to assemble it. your not gonna be revving it to the moon. thats what im gonna do with the short block in the garage.

Heh yep! You have to realize this, if your teacher has a brain he will tell you NOT to buy a used engine and upgrade it. 1. You don't know what it has been through, 2. It's used and there usually is a reason for it being sold and 3. Would you buy used underwear? Same principle. You MAY luck out and get a good one. Just save the money and do it right. My engine has 215000km and running strong, burns about 1/4 litre oil every oil change. Putting higher flowing parts on an older block can cause many things to go wrong. Take it from me and everyone here, just do it right the first time.

Yeah the car could have been wrecked or stolen or whatever. Doesnt mean automatically the motor is bad

Thank you for tellin me what I wanted to know instead of what "I should do".

You also are taking the chance that maybe when you think you have found a good motor then you take it to a machine shop to get new bearings and boring the cylinders plus the cost of the motor your still looking at about 700. So why go that route??

 

[Rice_slayer]

Let him learn I guess. I have been fornuate enough to learn that used is never good. He'll spin a bearing some day and come back crying. Best of luck with your build I guess.

Lol dont wish that on me just like I wont wish you crash into an 18 wheeler and ruin that front fascia of yours. Honestly I have no problem with constructive crits, but I dont need the extra.

 

[Rice_slayer]

lol I crashed it last winter by driving it when I shouldn't have been :violent1: Thats why the hood/front bumper are on it now. Just saying, you get what you pay for is the most true for the automotive world,and if you plan on doing anytime of racing/owning the car for any length of time, the smartest thing would be to start fresh. Plus, as it's been mentioned, it's cheaper to get the $700 block then to get machinists to redo an older block.

 

[duh09]

You asked, we gave our opinion.

If you want a good budget engine, the LMR shortblock is a good way to go. That $700 is a set price. You go into buying a used junkyard motor, you're taking a big risk there because you really have no idea what'll be in there and what you're getting into.
The cheapest route isn't always the best. Sorry if thats not what you wanted but there it is.

Good luck.

Were trying to help you not have to go through what others have gone through. We don't want you to find out the hard way. It would suck to hear you post after you have done all that hard work to find 20 miles down the road you spun a bearing or something.

 

[BruhBrahBrad]

I know, I know. LMS says they have it .30-.60 over what is .60 a 308?

I know you already have a game plan together and are just sorting out the details but there is another option. If you have the will power to set money back, you could just save money till you have enough to build the complete engine. In todays economic times there are deals to be had if you have cash in hand. While saving up your money continue searching classifieds in search of someone that has fell on hard times and needing to get rid of their already built engine. You could luck out and find someone selling exactly what you are looking for (for half of what it would cost you) and you'll have the money in hand vs half the money and a box of ebay parts. If, at the end of saving your money and not finding any deals you'll have the money to finish your project from day one. Plus, when planning out an engine build you'll change your mind several times. Over the time of saving money you'll know exactly what you want and wont waste money on selling parts off from idea changes. It took me years to finally come up with the plans and money for my build. Just the shortblock plus heads and oilpan cost around 7500 and hasn't even been installed (actually hasn't been delivered yet). If I walked into work tomorrow and found out I was losing my job it would be in the classifieds for 4500ish because I would need the money to cover me until a new job was found. No matter what route you take good luck with it.

+1

But it would be better to buy one from corral, or a car enthusiast site, because usually they are in better condition, or peaple are upgrading and selling their stock blocks. That short block from LMR was used at one point too. But its been rebuilt for you. A easier goal to acheive (and alot cheaper) would be to just rebuild a stock block and wait to build a stroker motor when you have saved up all the money. It isnt a good idea to build a "cheap" stroker.

just my .02

 

[BruhBrahBrad]

OK thanks for all the advice guys. I think If I just rebuild a stock block, I wont stroke it. Im still in decision and planning mode anyway. I doubt that this will even begin before the end of summer

 

[LAFENATU]

.040 over is a 308. I wouldn't have a motor any more than .040 over, that is just my opinion.

If your not in a huge hurry, why not collect parts little by little??

Keep this saying in mind.

Fast, Cheap, Reliable...Pick two.
