No enfines but I have gotten parts from them without problem. I googled complaints on them and found 2. Considering the amount of time they have been around and the volume they ,ost like;y do, Idont see 2 complaints being a problem

I got burned but good by 1800runsnew !! Granted it was on a reman , that was supposed to be new, I still have the ad somewhere, guys name was JT or something like that, real D.B. ! Should have sued his ass but just wanted to go boating. Was prob 10 years ago, learned a $5K lesson on that one. Ended up going with new short block. Hard to go too far wrong with new. I purchased my new short block from Scoggin Dickey down south .

Im sorry to hear that you got burned on a Reman like I have more than once....
the remans that 1800runsnew are from marshalls engine in Nebraska

who is aka 1st mate marine, and blueprint engines. Thats the only brand reman 1800runsnew sell and when I had issues with the remans i had bought from them years ago I dealt directly with marshalls. JT and John at 1800runsnew are salesmen. They both went to bat for me on those occasions but because Im a professional installer, I was better off speaking directly with the warranty/re-manufacturing co. Which I learned.
I have heard that marshalls in nebraska has cleaned up thier act somewhat but I would never go back to remans for sterndrive engine needs.

on another note; I do use a reman company for outboard powerheads that we dont do ourselves though, any time I have an issue with one of those they send me another lickity split Outboard recycle inc.

Thanks O'Connor. The ad said new , when I hoisted the second engine after already installing the other , I noticed the " remanufactured " tag and flipped out . Decided to take the loss and get my boat running again and installed it anyway, engine lasted 2 hours before spinning a crank bearing , got no help from the 800runsnew clowns . Pan looked like it was put together dirty , full of sludge. Wont ever do a reman again! Really wanted to drive up to Holliston and hurt someone!!

I bought 2 new gen VI 454's a while back no fuel pump boss, found out there are assembled by a off site vendor for GM, using scat cranks, mine had a vibration from day 1, spun 2 rods bearings @ 125hours, now this was in my Gibson that never saw 4000, whole life @ 3000-3400. got nothing from where I bought them but the run around, was not the site listed above. bought new crank from scat factory GM balance, machine shop was barely able to get it to balance !!!!

As tempting it is to buy a reman at those prices, I can see that would be a huge mistake.

Why don't you rebuild the engine you have? That way you no exactly what your getting and much cheaper.

Had a friend who bought a new 502 longblock from 1-800-runsnew, and had no problems with it, but it was a new GM motor, and that was probably 15 years ago.

7.4 mags i say u should be picky. 7.4 mpi is a truck motor with a $230 gm crate cam. My kids can build one of those that will live and not burn oil.but they are obsolete and have been dying off a freezecracking death for years. Thats the problem. If. Its a mag , i would be thinking about a 502. If its not , id be thinking about a 502 takeout. There is always jasper, just make sure you get the RIGHT CAM .
