As far as Paris modding it, quite possible but I think Ron passed away in 2001. So it depends on the year. I had one of his .12 touring car engines. That thing had a mid-range kick that you thought a single speed touring car had a 2 speed in it.
The sbk is a short stroke. Lots of bottom end but not the best fuel economy. I don't remember many people pitting longer than 6:30-7 minutes with one. The p5 basically replaced it.
