    Rated 5 out of 5 by from value Fast shipping the motor arrived two days after it was ordered The rebuilt motor quality appears to be fine , all the threaded holes were clean and in good shape the gasket surfaces were clean and smooth , the intake fit fine . The whole install went well and the motor fired right up and runs well . I looked locally for a used engine they wanted 900 to 1000 for a motor with over 100000 miles , so buying this motor was a good value for me.

    Rated 5 out of 5 by from Fast and easy shipping I bought a 94 k2500 with 250000 miles and a dead cylinder. After shopping around I found this engine to be the most cost effective choice. Ordered the engine on Friday and it was delivered to me the following Monday. Everything bolted right up (minus the exhaust manifolds, they needed some persuasion). I wouldn't hesitate to purchase this engine again.

    Rated 5 out of 5 by from Awesome motor I bought this motor in February and installed it myself, which was very simple but u have to have some mechanical experience, but I was short an oil plug and I called jegs and they expedited one out to me which was great customer service and been running awesome since day 1. Very pleased but make sure you have oil filter adapter to bolt on or a new one and also make sure u do the break in process to a T.

    Will this block work in a 4x4? My 1990 350 block that is bad has an oil filter that mounts 90 degrees to block and angled 45 degrees outwards. I see this block mounts oil filter facing directly down. Will the front driveshaft have clearence?

    Asked by: 1990k1500chevy
    You would need to check that, there are oil filter adapters or remote filter kits that will allow you to use this engine.

    is there a core return or charge with this long block? Do you require a certified shop to install for the warranty? What state would this long block be shipped from ? How long would it take to arrive to Utah?

    Asked by: JJ the man
    There is no core charge on this engine and you can install the engine and keep the warranty. This will ship from Ohio and will normally take about 5 days to be delivered in Utah.
