I just read the engine specs here
588 R Crate Engine and to be honest I think it's a pretty uninspiring parts list and power level for the money.
I bet that a regular contributor to this forum Brent Lykins could build you a better motor for less money.
Lykins Motorsports, LLC (Or for another couple of grand you could have a Boss 9 headed monster!)
Depending what you want to achieve with the car, you might also like to consider fitting an FE big block - cool looks and again for less money than the Roush motor...
