Probably very fast compared to the trucks I'm referring to - high 2.00's or low 3.00's. There is a world of difference between a stock/tired 305 with high gears and a healthy (albeit stock) 4 bbl. 350 that's geared for pulling. I read a road test from the early 80's that pitted two shortbed K10's against each other in acceleration, towing, fuel mileage, etc. - one with the then-new Vortec TBI 4.3 and one with a carbureted 305. They traded off on which one had the better result in said test, but were never very far apart - that is to say the 305 is no powerhouse and no comparison to the powerplants they put in the trucks designed for real towing - the 20 and 30 series. If you've never been in a pre-'88, >8,000 GVW truck pulling a couple tons or more (even just as a passenger) you should take the opportunity if you ever get it - they can't be judged by their numbers alone.
