3.08's and 33's aren't a horrible combination, definately not the end of the world. You won't be setting stop lights on fire, but still very driveable.
I had an 84 blazer with 3.08's and the 700R4, and actually had a bone stock goodwrench 350 in it. Drove that for years, wasn't all that bad with the 3.06 first gear. Was just a driver though and was never interested in changing much else on it.
My current 72 blazer had factory 3.07 gears, I threw 33's on it. 350 turbo only had a 2.52 first gear, and the 355 was mild, forged flat tops, small RV type cam, performer rpm intake and 750 holley. It actually would get up and go decent considering. I modified the trans governor to hold the part throttle shifts longer for around town driving which helped alot with stop and go. Still knocked down 13 mpg city and 16 mpg highway.
Switched to a 6.0 LS engine and 4L60E, left everything else alone for a while. The 3.06 first gear and 1.62 second pepped things up, and it would actually lay some rubber with the 33's.
After a year of that I swapped in a set of 3.73's so I could enjoy more of that 6.0 and I think the setup now as a whole is about perfect.
Gears are funny like that though, you could put 4.88's in a 6 banger and feel like it would rotate the earth
I have a couple other cars here with 4.56 and 4.88 gears, heck of alot of fun.
