Has anyone used DND's 327 or 342 motor or know someone who has. Is a 327 or 342 better or worst than a 331 or 342. I know that its a 302 with a 331 or 347 stroker kit in it. DND's short blocks and longblock look like a good deal for having all forged internals compared to other companys.
Forged internals are useless in a stock block. The block will break before the stock rods or crank will. The 327 or 342 is just a stock block with a 4.000 bore instead of a 4.030 bore. The .030 would make the 327 a 331 and the 342 a 347. There's not much of a difference other then you can get 1 more rebuild out of it before you have to junk the block or sleeve it.
