More hp 305
#12
GMC Yukons never were offered with a 305. In 2001 they were only offered with either a 4.8L (290ci) v8 or a 5.3L (325ci) v8.
My opinion, just swap out to a 350. It's easier to make hp with that.

what dont you want to do to the motor? you can get a set of torquer heads, aluminum intake, little holley carb, and a small cam, but the gain isnt worth the time or money. it would only be fair to say that 305s have been known to make ok power and people do stroke them, but for the time and effort it would be better to start with more cubes.
I'm not trying to be a smart ****, but the term 'quick 305' is an oximoron. I've beat the pants off of so many 'BUILT' 305 with a STOCK 350 it's made the owners go home with their tail between their legs and tears in their eyes.
