johnj92131 Posted August 1, 2013 Share Posted August 1, 2013 A fellow not too far away from me is advertising a 4.7 long block with "23,000" miles. He is parting out a Wrangler. What seems like a reasonale price and what should I look for? I am looking at spending some money to get the current engine, but with 240,000 or so miles. Maybe it is time to look at a Stroker for replacement? My truck is a 91 with AW 4 two wheel drive. There is another fellow with a 2001 engine out of a wrecked Grand Cherokee for $450 that may be interesting. Any thoughts appreciated. Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted August 2, 2013 Share Posted August 2, 2013 Depends on what kind of abuse he's put on it and the maintenance he's done. I got mine built for $1800 brand new, but after everything was said and done, I tied up about $3200 total into it between intake mani, header, HO power steering pump, HO fuel rail, Hesco FPR, 24lb fuel injectors (which I got free), 62mm throttle body, etc. etc. But... I was putting into my '88 XJ which is Renix. Could have reused a lot of my old stuff despite the intake mani ports not lining up right but I chose not to do that. Anyway, bottom like is, if all is well with the engine in question, $1000 is probably fair, assuming it's just the block with no accessories.

What seems like a reasonale price and what should I look for? John, what year is the Wrangler and what's the reason for the part out? Wrecked? Was the engine running before the part out? Do you have any build specs for the 4.7L engine? Bringing a used non-running stroker engine back to life can be expensive. Since it's 4.7L block it's been bored and unless the seller can provide the engine build details I'd pass. If you don't need a stroker I'd opt for a known running low mileage stock OBD1 engine from a wreck or yard. Link to comment Share on other sites More sharing options...
Pete M Posted August 2, 2013 Share Posted August 2, 2013 he better have some paperwork that proves what it is. and that paperwork better have a block number on it that matches the engine. and that paperwork better also have a phone number of the place that did the work so you can call and verify with them what's what. and I think you can pop off the oil pan and check the crankshaft to check of it is from a 4.2, though I've forgotten what you'd be looking for. :( part number maybe?

87Warrior Posted August 2, 2013 Share Posted August 2, 2013 That 01 WJ motor will not bolt into an MJ/XJ. If the Wrangler is a TJ, that stroker will not bolt into an MJ/XJ. Link to comment Share on other sites More sharing options...
HOrnbrod Posted August 2, 2013 Share Posted August 2, 2013 That 01 WJ motor will not bolt into an MJ/XJ. If the Wrangler is a TJ, that stroker will not bolt into an MJ/XJ. Exacerly Brett. That's why I asked for the year. In a perfect world Pete, that's cool. But a wanna-be DIY engine builder using a stroker recipe he found on the web, built one himself or farmed it out to a local machine shop, and it actually ran (for a while), that's pretty common on the stroker forums. While I admire the DIY attitude, it can end up costing a lot more in the end than buying a built crate from a reputable supplier. And sketchy paperwork at best.

Pete M Posted August 2, 2013 Share Posted August 2, 2013 absolutely. and if it was done is a DIY fashion, I wouldn't touch it. (unless maybe I could drive it around first) Link to comment Share on other sites More sharing options...
johnj92131 Posted August 2, 2013 Author Share Posted August 2, 2013 My thoughts exactly. Why pay for crap built OR unknown. Hesco wants $6K for a long block + freight OUCH. My current engine and transmission are hemoraging oil and cost to fix will be high. Thinking might be a good time to rebuild, to to find a good shop takes a bunch of leg work.

HOrnbrod Posted August 3, 2013 Share Posted August 3, 2013 Kevin - I respect and admire you for giving it a go. I didn't have the guts to even try. Been following your build; your truck looks super mate. She will be up and running soon. :cheers: Link to comment Share on other sites More sharing options...
johnj92131 Posted August 3, 2013 Author Share Posted August 3, 2013 where is it losing oil? Front main seal and maybe other places. Trans leaking from seal on tail shaft (again) less than 15K miles on a NOS seal I got several years ago from Don. Something must be wrong in trans. Seal should have lasted much longer. Original owner installed used engine at 98K miles, now 240K miles on truck but it does start easy and run smooth. So maybe cheaper to just get the engine oil leaks fixed properly is the way to go. Still leaves the trans leak as a problem. Stroker long block is gone from CL, asking price was $800 2001 Grand Cherokee engine still there for $450, supposedly 150K miles.

FrankTheDog Posted August 3, 2013 Share Posted August 3, 2013 As far as which engines you can use in your 91 (which if it's running good I would just reseal it) you can use any non coil pack HO engine. Wrangler engines will work as long as they're not coil pack engines. You just have to put your throttle body and sensors on it. 97 and 98's will need the distributor swapped for your old one. Also put your water pump from your 91on the front. They have different length water pumps There is even a boss on the back drivers side of the head for the temp sensor that you can drill out on the 97-99's. One thing to be careful with though is 92 and up engines have a different size pilot hole in the end of the crank. You can use any auto transmission up through 96 will plug in. Oil leaks, valve cover, oil filter adapter and rear main seal are the biggest culprits. Link to comment Share on other sites More sharing options...
