Everybody is quick to rag on the 351M/400 engines...but, if kept under 4,000 rpm they'll live a lonnnggg time. :D
It's all the guys that treat 'em like a chevy 350, and wind the piss out of em and blow 'em up, then bitch about how Ford engines suck. :flame:
But a good thing is...a 460 will bolt right in where that 351m sits now
