yeah a 22r only weighs around 300 lbs. a small block longblock only weighs around 450lbs. and I'd say that the small block we had on the kragen 1000lbs stand, only weighed 600lbs with the cast iron manifolds and marine gear on it.. but it flexed pretty crazy when we had to roll it across the shop. i like the extra wheel because i have to move across uneven surfaces. just something to think about
