reverse flow cooling
my question is on the reverse flow that just the water pump right they will work on a regular block also are thses center bolters and do they work with the older style intakes or does it use the vortec type

You are correct. Only the pump turns in reverse, the water flows the same direction.

I asked the question before myself and didn't get a good answer - From what I understand the coolant goes to the heads first then to the block - that is exactly opposite of the 'old' style cooling.

I would also like to know if I could fit them on an early block since they're cheap (around $200 for the set), there are factory iron intakes available for them and the flow numbers look as good as the vortec's for classes where vortec heads aren't allowed.

For a blurb on reverse cooling info see: http://www.h-body.org/people/projects/building_lt1/lt1%20info.html http://www.stewartcomponents.com/html/forum/viewPost.asp?m_id=1896
