Fuel injector choice?

[Thomas Martin]

I am starting to gather enough info to PFI my 77 Olds 350 in my 85 Cutlass this
summer, and would like some input on what is the better fuel injector to look at.  The
Multec or Bosch?  Or is there another?  Is the late 70's Cadillac (Olds) 350 with EFI
a port type? Can I modify my factory alum intake (from 82 307) with injector boss's?
Or is there any reason to use the stock 77 iron piece instead for PFI?

Thanks
