350 or 305

[fatboy]

looking at buying an 81 blazer. The guy says he bought it from someone who said it was a 350 but he is unsure. What numbers do I need to look for on the block behind the heads?

If its extremely nice and all there , and has a 305 , it will be easy to go 350 later . I'd rather replace a motor than body/interior work /forums/images/graemlins/k5.gif /forums/images/graemlins/k5.gif

I wouldn't let a 305 scare you though, they are still good motors.
