I didn't know they still made engines that start with a "3" :?
Well a 400 factory block isn't the best foundation for a race engine, some people say, but if you are going to use one might as well at least use the factory stroke crank....On the other hand, I would be leary of spending the cash to build a 427 ci small block with a factory 400 block. If you decide to build a big inch small block I would strongly consider a dart block. JMO based on what I've read/heard about the stock blocks
Then on the other hand..if you are going to buy a Dart block might as well buy a BB for a few hundred more and build a 565. :lol: That's what I'd do.
