Number Crunching / Re: 400 casting code
« Last post by rkellerjr on Today at 06:15:10 AM »I think the 557 block has a much worse reputation than it deserves. Buttler Performance uses the 557 block in builds up to 450 or 500 HP, I don’t remember which. Obviously there a lot of variables that come into play when building an engine other than just the block. Probably just as important to have it done by a competent shop.
The shop that did my motor work was aware of the 557 reputation. He said yes, it is a weaker motor but, he said, done right, he could push that block to run 600hp without issue. He said while you don't want to build a quarter mile beast with it, you can build a very nice street machine.
