Even Kary balked at the expense and rarity of the Typoon/Cyclone when chossing engines for doing his 4.3 back when. (It was the factory turbo version of the 4.3 just for them as what ain't in the know. Very powerful!)

Those are hard parts to find.
Have yet to see even one in all the scrap yards I've toured.
Of course the parts can be bought from the dealer, but at what co$$$$t ?

Mind you, that would be an incredible power plan to have in there!

Certainly it would not be a swap for the faint of heart, and especially not for those who found the 4.3 CPI / 4L60E swap too much... <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
