Hello everyone - I'm looking for a remanufactured 5.3 LM7, with all the different suppliers (Jasper - Powertrain products - Blue Print - S&J Engines - Powertrain Max - Engines direct - ATK and on) With a ton of mixed reviews and questionable suppliers, trying to sort through the clutter. Does anyone have any recent experience or opinions on who to consider and who to avoid?
he means a 99-07ish Chevy truck 5300 LS engine. They're still around used. Why spend so much money? I picked up an LQ4 last year for $750 a few miles from me on fb marketplace. Took it apart, replaced just a few parts, put it back together, and with a little boost it's running tens.
It's a GM 5.3 LS engine from early 2000 GM trucks - just so many builders stating the quality engine builds but mixed information and customer reviews. Hate to buy a boat anchor or extra problems.
I replaced the cam, valve springs, timing chain, pushrods/rockers, gaskets/seals, and head bolts. Reused the pistons/rods, rings, bearings, lifters, etc. It had 150k miles on it, which is about half way through their normal lifespan.
