for all the talk and hype chevy guys make over hte 350, it felt just like a 302 and 305 when i got a truck that had one. it didn't roast the tires or pull any better then the smaller displacement v8s.
i had an 85 f150 with a 302 that would light hte tires up all the way through the intersection and pull two tons like nothing. then i had an 88 c1500 with a 305 that would smoke the tires a little and pull one ton with a little work. then i got a beautiful restored 79 heavy half gmc with a 350 and it acted just like a 305. it ran great and would smoke the tires a little but it felt just like a 305 and neither chevy engine smoked the tires or pulled like the 302 did.
i could never figure the hype out over the sbc 350. i will take a 302 any day of hte week over the smaller chevy v8s just from the experience i had with the different motors in my personal trucks. i used them all while i did plumbing so they weren't just play trucks either. the ford was a real puller compared to the chevies. i had to go get the ford to pull hte 88 chevy up a steep incline once when i had a bit more then one ton on the trailer. that poor 305 isn't a towing motor, at all. it runs great and is just as reliable as the 350 and 302 but is not a puller
and you can get a fuel injected 302 from a late 80s to early 90s mustang for cheap because those cars are so plentiful. shoot, there are late 80s to early 90s f150 all over craigslist for less then 1k and they share the engine and transmission from the mustang, usually. then you get wiring harnesses and everything with it, fuel pumps, everything.
i am sure you can get an 88 to mid 90s chevy for the same price though, if you specifically want a chevrolet motor.
