Know what you are talking about , sometimes the original part are nowhere to be found , or a cheep quest for power , as for studebakers I have had a few years ago , Larks , a avanti , and. R-2 Hawk , parts were scarce then worse now unless someone is reproduceing them , they were ahead of their time , and now sometimes you have no choice but an engine swap , and some pick the wrong engine for the swap , Too big , and too much cutting to make it fit, my 79 Cruze Wagon project still sits engine less right now (removed to put in my76 after it was run hot) and still have not made up my mind what to put in it , a few options at first was to find another 2.8 to overhaul and install , but parts are kind of easy to find , next was the 2.9 , yep it's a bolt in and more power but it was last made in the early 90s , next was a Diesel engine out of a 240D Mercedes, yep I should get 40 mpg and last forever but 0 to sixty in the next three days , last one is the 4.0 out of a ranger , good power , bolt in , but not made anymore since the late 90s ,(got one) still have not made up my mind yet , but still like to have a 61 champ 😎
