[Diy_efi] Converting from Carburation to TBI

[Scott Pearson]

If you're really set on TBI, use the Caddy intake, plug the injector ports 
and install a TBI unit on it. Bob Valentine was using a TBI w/o injectors 
for a throttle body on his Cutlass.

I believe that Caddy intake will bolt up to just about any Olds V8 (Bob's is 
on a 403).
