My OCD want to grab a rag soaked in CLR and go after those rust stains... which is completely irrelevant to the functionality of anything. The way she chugs when turning over would point to a timing thing, but she runs smooth once fired..?
I have a 3.0 scarab I wanted to 5.0 swap , could I use my existing drive with a 4 blade prop for a season ? And then swap it later down the road or could I use a v6 drive because the 5.0 is a sbc?
