Hi There,
yes I have one of the SPF cars in Australia. Mine is a Ford 347. I like the combo and I am starting to get to grips with the handling. For me I think I have enough HP for the car, more would be fun, but for me not necessarily faster.
I chose that combo as I wanted a Ford engine. A GM would also do well, and would likely be a better price/performance option if you don't mind the engine heritage.
It would be great to see another SPF at the events... We need the numbers!!
Anyway, there are a bunch of pics in my gallery of how I set it up. I would be happy to answer any questions you have on or offline.
Regards
Cameron
