roush does have some problems tuning the the 8 stack, so I have heard.
I have a 427 roush engine in my SPF and I did not hane any problems with this engine
in my SPF. There is a tiny
oil leak, and I do not know were it comes from and it does not matter to me. These engines will leak a little, but this is normal for the type of applicition
in these cars.
Get them to tune the 8 stack, which is kind of overkill for street use,of course that is my
opinion.
Good luck
