Well like some of the guys here are saying the I6 is a nice suprise instead of the SBC or BBC engine.
I myself am in the process of putting a Clifford 4-barrel intake and 390cfm Holley on mine. Also with a Flowtech headers which should wake up my lil' 250 ci. In fact I may even put a mild cam in it as well.
I just think if done right they will draw more attention the the standard V8's do.
But hey that's just me.
