GM TBI on my 1970 360 duster

What pressure pump are you running?

I have a fuel sending unit with a 3/8 outlet dia. w 5/16 return it is not installed in the cleaned out and repaired tank. I'll put a couple Walbro fuel pickups on it to compensate for not having tank baffles.

I'm going to mount a VSS from a Jeep to read of to ring gear.

Because this car has Factory air and all the under dash space from the gas pedal to the passenger manual vent is packed full by the heater ac boxes. I'm going to extend the GM harness and mount it under the passengers seat.

I have the complete dist from the GMC and am thinking about changing the shaft and assembly into the Mopar dist out Affordable Fuel Injection have one done that way for $400.
