...and that's why I'd have no problem using a 100K mile unit in a street/strip car, even without rebuilding it. Short cab rams, vans, and Dakotas with 100-120K down here are going FOR 8-1200 bucks, complete, running, driving.
Watch out for cracking heads on them magnums tho. Im doing a magnum head refit on my 74 318, but im going to use the EQ magnum castings with the pre magnum headbolt style machining.
