Don't see that any one has mentioned that the Edelbrock setup is LA bolt pattern only. Not an issue if you don't already have heads with the vertical Magnum bolt pattern.
For me, I would have to add the cost of new/different heads to run the ProFlo4.
AFAIK, there are only 2 off the shelf EFI intakes for SBM, the Edelbrock Victor and the Hughes, one each for the different bolt pattern.
