Sold the 350 and trans out of the Suburban and got a 5.3 to swap with a 4L60. It's going to the back burner for now and the cutlass is coming home! Motor is going on the engine stand and hopefully she runs! I do need to round up what parts I have for the differential so I can reassemble/make sure I have limit slip and decent gear for it! It will be a stock 455 with a cam and a switch pitch 400!
