    Rated 5 out of 5 by from Just as advertised . . . I purchased this engine for my 1998 Chevy Tahoe 2D. It was a plug-and-play factory engine replacement that performaned excellent. I highly recommend this replacement engine, you cannot go wrong. I had mine painted in hanger orange as and to history; I only wish the engine came in that color straight from JEGS.

    Rated 5 out of 5 by from Another good product from JEGS I purchased this GM crate engine to replace the tired old one in a 96 Chevy Truck. Item was shipped fast and packaged well for shipping. Very impressed with the quality and craftsmanship when removed from crate. Installation was very smooth and the truck runs great with way more power than it ever had before. Thank you for the quality products and service once again JEGS.

    What side dipstick does this have? Do I need to get a plug for the opposite side?

    Asked by: Elias8373828
    This is a passenger side dip stick and does not need a plug for the other side. This is the recommended dipstick and tube; https://www.jegs.com/i/Chevrolet-Performance/809/12551154/10002/-1 https://www.jegs.com/i/Chevrolet-Performance/809/12551144/10002/-1

    It does have the r as the eight character in the vin. The other question I have is this for fuel injected engines?

    Asked by: Kennethrichar
    Yes this is for VIN with R engine character, these are for use with factory fuel injection systems.

    I have a 95 C1500 with a 305 TBI, will this 5.7 350 Long Block drop right in?? Will all A/C, P/S and other accessories brackets match up from the 305 TBI engine??

    Asked by: BigWaveDaveAZ
    This is the '96-'00 version with Vortec heads, your intake manifold won't bolt up and some accessory brackets won't fit. We have some engines that are a closer match but you should call and speak to one of our techs to see what all may be involved in changing over to a 350.

    Will it fit in a 1996 Chevy Silverado K1500 5.7L V8 Vortec with a 4L60E Automatic Transmission in it? If unknown would it help to have the vin?

    Asked by: KennethRichard
    It should fit, but you need to check for VIN engine code of "R"

    I have a 1998 gmc sierrra with 305 cid. Will this work with my computer and wiring? Anything else I would need to change?

    Asked by: ORJW
    Yes, you may need to tune the EFI , but this will work as long as you swap all of the parts from your original engine.
