The manual has install guides for everything from a 4.3 up thru the 5.7.
These work on a 4.3? Ooooh! After last spring's road trip, & being down to 50mph, in 3rd. gear, foot through the firewall on some of those hills, the added power that that would add would be so much better. Wish I could afford that right now! GLWS!
