If you use a four wheel stand, it will be a lot more stable as Ken mentioned.
You will also be able to put a 4x4 across the legs and a 2x4 on top of that to help support the weight of the longer 6-cylinder engine.(Not needed but it just makes things a little safer cool )

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!
