So I'm thinking about putting a newer engine in my car and wanted to get some ideas. The engine in my 98 has well over 137k which is what shows on the broken odometer. I don't have tons of cash so here's what I'm thinking of. 2008 4.6 out of a crown vic that has around 15k and swapping the intake and plenum. Id probably put a new pi intake on it though. Right now on my engine I have a 75mm throttle body k&n intake and the diablosport predator. I'll prob get a new plenum, long tubes macs, x pipe and exhaust. I saw the engine on craigslist for 800. Trying to get more power without spending a crapload. What do you guys think???
