what is a 557? when I did my headers ai was told long headers are better by all the shops around. better flow and horse power, if you y them into a single 3 inch gives a better low to mid torque and good scavedge to

557 is a 460 80 over and stroked. generally 80 over is bout max on a stock block. I used a DOVE block after stonic testing it. It is my daily driver, so not looking to make it too wild, prob will be a torque monster.
thanks for the mad dog info...looked it up..still same issue..inside frame or fender? and pros/cons

My opinion, outboard is the wat to go. Easy bends, no heat soaked starter to deal with & a straight shot back. Mad Dog use big tubes, L&L's are smaller. I don't know about Hooker but I'm sure the price would be steep.

These look right for a 557" streeter; http://cgi.ebay.com/ebaymotors/80-96...=p4506.c0.m245
Or these; http://cgi.ebay.com/ebaymotors/Ford-...=p4506.c0.m245
They look nice and the price is fair.

You'll have to "ask the seller" a question to be more specific with your application.
Edit; I didn't read the first ad carefully enough. Oops. The second one looks like the ones you want.
I'm probably wrong considering the price but those look like stainless steel. Or very shiny mild steel.
