    Chevy Crate Engine Break-In Guide

    12681429 is rated 4.5 out of 5 by 43.
    Rated 5 out of 5 by from Good pick I bought and installed the engine about a month ago. Fired up immediately and idled perfectly . Engine is running great with a solid sound and good power response. I have no complaints. My only concern when ordering the engine was a lack of any warranty should it fail in the future. GM will only warranty if they install it at their dealerships. I confirmed this via my local dealership when I called.
    Date published: 2018-04-25
    Rated 5 out of 5 by from Fast shipping I ordered on the Black Friday sale, Monday the trucking company called, said they would deliver the next day. Tuesday the truck rolled up, and I had my crate engine sitting in my garage. Don't have it running yet but it's going together as it should. Chevrolet could have sent better instructions, Google is your friend.

    Rated 5 out of 5 by from Chevy Motor and Jegs Bought the motor for 1976 Blazer K5 Chalet. Bought with the carb , distributor , and intake and valve covers. Arrived very quickly 3 days. The install went smoothly. Fired right up and broke in the cam as described in the instructions. Have 150 miles on it now and very impressed with the product. Great power and low end torque. Changed oil at 100 miles and am ready for a road trip to go deer hunting. This is a great product and the Jegs Tech adviser answered all my questions prior to purchase. This motor has the 260 HP easily. I think its probably closer to 285 the way it is set up with the headers. The Jegs company will get my business from here on out on products they sell. Gret product great price and a great buying experience.
    Date published: 2017-09-04
    Rated 5 out of 5 by from Best Buy for the Money I built 1932 Fords, I have bought 7 or 8 of the Crate 350 Chevrolet engines from Jegs. I have never had a problem with any of them. They start up and run extremely well, no oil leaks, great oil pressure. I install 3 deuce carb. intake for that hot rod look. It don't get any better than that. What a great way to put a hot rod together. You better believe that I would recommend a great deal like this to anyone.

    Does the warranty (3yr/100,000 miles) only apply if the engine is installed by a dealer? Or would the warranty still apply if I install the engine myself?

    Asked by: JB_5301
    The engine will need to be installed by a certified mechanic - here is a link to the warranty information - https://www.jegs.com/customerservice/GM_Warranty.pdf

    Hello, Would this engine be covered with the 3 year/ 100,000 mile warranty if installed in a 1972 chevrolet truck(c20) ?

    Asked by: Mike E
    This should be under warranty, but the dealer that does the installation will need to determine that.
