Reman/crate/rebuild June 10, 2013, 11:53:12 AM I have a 91 302 ho motor, that needs rebuilding. Should I sell it as is and get a reman/long block, or crate motor on summit racing. Couple reasons I am thinking about this is, warranty, and I am not looking to drag race car, I just want a good cruising car and sound good. Any advice? Quote Selected
Reman/crate/rebuild Reply #1 – June 10, 2013, 01:49:50 PM Rebuild, if the cylinders aren't funneled out. If you do go with a remanned engine, do some research...some cheaper outfits don't care about longevity. At least with a rebuild, you KNOW what's inside the block when you put it in the car.If you can still see crosshatching on the cylinder walls, then you're already at a good point. The HO cam will live for a long time if decent oil changes have been done. They're roller, so they tend to be longer lived than say a flat tappet cam.Throw some GT40 heads on during assembly, and an Explorer intake and TB, and you'll be up on some power over the stock HO stuff.My own opinion: I wouldn't dream of dropping coin on a crate engine....unless I had a lot of cash, little time, and needed a built engine...then I'd go to Ford Strokers for my need. For a stock type rebuild, it;s easy enough to do it yourself, if you have a clean dust free place. If you have a good basp00get with an entry door, you can make your own little dust-free "operating room" with some 2x4s and some sheet plastic. The rest is just simple cleanliness and common sense. If it's clean enough to make a sandwich on, it's clean enough to put in a car. Quote Selected
Reman/crate/rebuild Reply #3 – June 10, 2013, 09:14:49 PM I got a motor from autozone for 850 shipped to the closest "hub". picked it up with just me and my dad, set it on the back seat of the van. no core charge. this was about 2006 and I never did put any real miles on it though. Quote Selected

Reman/crate/rebuild Reply #6 – June 11, 2013, 03:04:58 PM If you are lucky and I mean lucky you might be able to get away with a hone job and just re-ring the pistons. From there (staying with the really lucky theme) the crank would get polished and new rod and main bearing would be installed with a new oil pump. Put your stock cam, lifters, and spider back in and install a new double roller timing chain. Now you have a freshened up short block.The heads would need a valve job at a minimum and I would have them check the block mating surface for squareness. Add a new water pump, thermostat, check the harmonic balanced (replacing it is super cheap and good insurance), and new gaskets. Now you have a freshened up long block.My biggest question is how many miles are on your stock 91 HO motor? I've seen the short blocks go 200,000 with zero issues. Typically the heads are what go south and give up the power due to needing a valve job.I would do a compression check and a leak down test if you suspect power loss before you haul off and spend a bunch of money.

exploder engine FTW Reply #7 – June 11, 2013, 04:39:54 PM I would find the lowest mileage exploder/mountaineer 5.0 I could find...Its a great performance swap. Exploder 5.0 gives you good upper and lower intake, 65mm TB, GT40/GT40p heads...They will make 300hp easy...and live a nice long life...I agree with above....about having everything check...but if you find a sweet heart engine...you could just swap cams and valve springs and go for it...You will need to use your HO cam, oil pan, accessories....You can get complete exploder motors for $500.Travis Quote Selected

Reman/crate/rebuild Reply #10 – June 12, 2013, 06:24:33 AM Thanks for the advice, it has crossed my mind to find explorer motor and go that route, as far as a leak down test or anything, motor is apart, pull cap on two of the mains and cooper is showing. Quote Selected
Reman/crate/rebuild Reply #11 – June 12, 2013, 12:35:36 PM You would have to swap oil pans anyways... So pretty easy to inspect...What r u doing for a tranny? Because the stock 83 AOD probably won't like the additional power!Travis Quote Selected
Reman/crate/rebuild Reply #12 – June 13, 2013, 12:40:44 PM I have a friend who is a mechanic so I had him order a "Jasper" engine for mine. It is an "87" Mustang 5.0 HO engine with a stage #1 cam. It is warrantied for 3 years and if the engine gives out my mechanic is paid to replace it by Jasper. I now have about double the horsepower it used to have and it runs great! If you can rebuild it yourself and you really know what you are doing, than that's the best way to go. If not having it rebuild is getting too expensive, so go with a crate engine with a good warranty and if you can drop it in yourself would be the next best thing. Quote Selected
Reman/crate/rebuild Reply #13 – June 13, 2013, 02:18:44 PM there is a lot of good advise in this thread.I got a short block, then.cheaper out and ran stock s.o. everything. only to eat the trans up. since I already have the short.block, I'm.gonna stay with the.h.o. upgrade. but buying an explorer motor would be a good deal if you want a bit more power.
