I agree, check the ratings on both for how much they will hold. Get a 4 wheel stand and get the beefiest one they have. The fold up hoist is a good one, and when assembled is stout.
Firebirdcrazy, I was told the Chevy BB is about 75lbs or more than the Pontiac Motor... and the Poncho is about that much more than the Chevy SB... I forget the numbers, but remember thinking that with headers and an aluminum intake on the Poncho, it wasn't all that much more in weight than a complete stock SBC... I'll have to look it up again. Anyway, the 69 396 I had on the stand was deffinately heavier than the 67 400 I have on there now.
Go for it John, just make a list of things you need before you go. It's like walking into a toy store...
