[QUOTE="scottydsntknow, post: 16071031, member: 79824"] Stock rebuild, and what is wrong with your 197k engine? If nothing is wrong with it just keep running it, 4.6L engines can go 300-400k with routine maintenance. My tuner has a 265k mile Mach 1 he's owned since new in 2003 and he is not easy on it... Smog place won't care about the cams unless the car is OBVIOUSLY cammed like it sounds cammed. Magnaflow makes 50 state legal pipes, I think flowmaster does too. They are like $1200+ tho... I'd just go get an original used one from CL and swap it in for emissions days. This x1000. And if someone buys an engine from Jasper then consider that a life lesson when it lets go... Lots of 8 bolt cast cranks out there, and cast crank is plenty strong. Get them for free or under $100 most of the time. Lighter than forged and unless you are shooting for 700+ no need to worry. Even then... Plus, unless you have some flywheel with a replaceable insert you'll be getting a whole new flywheel anyway when you redo everything, just get the flywheel that matches the crank. Or stick with the forged unit if you already have one and get a new 8 bolt flywheel... Super popular cheap/reliable/strong combo that'll be more than fine for 95% of street cars is a cast OEM crank, OEM Boss/15+ rods for $200 new, and your choice of $550 entry level forged pistons. And early 01s :) But every Mark VIII or Continental or Aviator engine I've taken apart has had the 6 bolt cast jobbers. Not aware of any Lincolns that ever cam with 8 bolt cranks. [/QUOTE]
