snip 84 monte carlo 5.7 diesel unsnip Bob, that's a new one on me. I never saw a factory 5.7 in a Monte Carlo. I thought I was the only one left with running 5.7L diesels. I have a 81 Eldorado with 269,000 miles and original engine and a 81 Seville with 297,000 miles with a just replaced engine. Now back to Corvair content... Frank DuVal 64 Spyder Conv
