The 70 Eldorado E car had similar HP and Tq so that is not an issue. I just don't think a low nickel BB Chevy (if that's what you are suggesting) will have the longevity of the Olds, but that will he offset by availability.


These are modern motors either all aluminum or iron block versions, that are typically good for 200,000 miles or more. They have NOTHING in common with a big block Chevy. Great platform in most applications, Corvettes, trucks, rear drive cars etc. Same bore spacing as the old small block Chevy but nothing else carried over. All had aluminum heads, composite intakes. 4.8l,5.3l,5.7l,6.0l,6.2l,7.0l sizes stock with lots of aftermarket support. All aluminum versions were in the 440lb range which is a real plus for weight savings.
