BAd news?
#1
Ok folks this morning I took a little trip ( 75 miles one way)in the car with my Uncle in his to a Ford dealer drive in car show. Well needless to say we played a little on the way up there. When we got there he said he noticed what looked like oil smoke when I would let off the gas????????? So when we got back to the garage my cousin drove the GF's Saturn home for me. He was following me and again said that when I shifted gears it would smoke. As most no this is a stroked 351c to 408. The rings are file fit ones, but with this stroker kit the wrist pin actually goes through the bottom oil groove. There is a bottom spacer ring that goes in the groove to make it a solid groove again. When I wipe the exhaust with a rag it looks like a black soot. Uncle is thinking on it so thought I would throw it out there. The motor is ALL new with all forged internals. Prob less than 700 miles, oil has already been changed once.

Soot can indicate a rich condition. You might check your plugs to see if they are also sooty. If it is a rich condition they should all be the same.

Yeah have to wait on the garage to clear out to start checking things. The carb has had nothing done to it except for the bowl levels set. It was bolted on from the box. Is there a chart or something that states what jets carbs come with?

Back in the day the jets had the size stamped on them. All you would have to do is take them out and adjust from there. I cant remember stock jets on a 750.
