Lot of gearing on the larger trucks. Mine only has a 272. (F-600)

I looked into the Lincoln engines, they seems to be completely different beasts. I'm still debating over putting a 368 into my truck they make a lot of power and it be cool to stay with a Y-block.

Problem that I've noticed with them is there seems to be no parts for them. Which means what you do find is spendy. Right now I'm leaning towards the diesel idea, but at the end of it all I'll probably put a 351w in it... or a 460. Cause why not, lol.
