1971/350 C10 EFI question

[steve ravet]

Paul -- buy the TPI/TBI swapping book from JTR at www.jagsthatrun.com. 
It is specifically for putting EFI engines into older non-EFI cars, and
addresses a lot of issues like fuel pumps, VSS senders, park/neutral
switches, fuel return lines, etc.

The book will recommend, and I agree, that starting with a complete used
engine that has the ECM, wiring harness, accessories, sensors, etc. in
place will result in a much easier swap.  Otherwise you'll be chasing
sensors and stuff.  It all depends on how much of a project you want to
undertake.

No fuel rail for TBI, but there is a return line.  Best would be to try
to fit an EFI  tank w/pickup and pump in there.
