@sargoysmuck @GabeLakmann @BowsacNoodle @Polfusilier @Victor_Emmanuel @WashedOutGundamPilot @johnbudd1350 2500 Suburbans are going to have a TH400 or 4L80E and NP241 or similar. Axles are semi-float 14 bolt and dana 60 or 9.5 IFS depending on the year. I don't think you're going to break any of that with a mildly boosted V8.
