Acually, if all of them are specified for this engine, It would all seem to be compatabe, except maybe for the intake and carb. Ive seen a few holldey intakes not like other carbs, but that can be cured with a spacer. Now, for my next question, who bought this stuff? They seemed to have taste. I would have swapped a few things over, but its a nice little ensemble you have there. If you do well, and the engine isnt fried, 300 is possible.
