Its probably a 1250 as thats just an easy drop in kit, and the 88" kit requires splitting the case, machine work, and will likely have cams and other work done to work with the increased displacement. I've never heard of a 1350 before, but I'd also never heard of an 1170 until magnesium mike created the beast.
The takeaway is that if you are concerned about a correct tune, you really need to know what the engine specifics are.
