These cars were designed to succeed on road courses, not drag strips. Best power plant to achieve that goal given modern suspension, brakes and chassis is -

#1 - LS Platform
#2 - Windsor Platform
#3 - FE Platform

That's why you see so many windsors in these cars, some can't bring themselves to go with LS even though they know it is a superior motor, but they can justify a windsor as an acceptable alternative to the FE, the FE being the least road course friendly of the bunch.
