I had 33" TSL swampers on 8" rims on my old 72 K5 with no lift.
Front tires cleared fine. The front leading edge of the rear fenders would kiss/hit the tire going over normal bumps on the freeway. I stuck a 1" zero-rate in and it leveled it out and made the impact less frequent.
10" rims will have a more negative offset and may cause some rubbing issues up front especially when turning and cycling the suspension.

NM, i just saw yours is an 80. Bigger wheel well openings. You're probably fine.
