What engine was it behind??

HeavyMetalChevy · 06-12-2012, 05:53 PM

It was behind 1999 5.7 Vortec. I can get some numbers if interested.

I was hoping it was off an LS style engine. Thanks for getting back to me,

do you still have it? do you know if it will fit one a 8.1?

HeavyMetalChevy · 07-24-2012, 04:43 PM

Hey you are close!!!! I will check

HeavyMetalChevy · 07-24-2012, 04:52 PM

Is this possible? In other words, if I take an 8.1L power plant with it's PCM and swap it into an older 3/4 ton Suburban that originally came with a 4L80E, can that 8.1L PCM control the older 4L80E? Or will I need to swap something out in the transmission?

It depends. If the 8.1L had a 4L80E behind, obviously yes. If the PCM had an Allison, but has the same OS number as a tune that had a 4L80E, then yes, do a segment swap. Also, if the 4L80E has the original style (91-92) internal harness, it will need to be updated. If its an 04+ PCM, will probably need an 04+ force motor in the 4L80E.

From other info I read it should mount right up. A lot of 8.1's had the Allison setup behind it but here:

Here is a list that I condensed down to the 4L80E for Chevy.
