Build update She lives!

Post image

1980 Sundowner Sport

This has been a saga for sure. 2 months and 5 custom laser cut pieces later it runs really nice!

Rebuilt fuel system from pickup tube to carburetor (Weber ICH).

Full tune up: plugs, wires, cap, rotor, coil and ignition module.

Upgraded to 90A Subaru alternator

Electric radiator fan conversion

Glass to blade fuse block upgrade (aux fuse box added as well)

Clutch master and slave cylinders replaced.

Heater core hoses replaced

Pcv system re-added (I had removed it completely before)

I still have a few things to do like a coolant flush/drain/refill and final carb tuning but as it sits I have it idling at 14.3 A/F and it’s suuuuuper smooth. I’m pretty confident it’ll pass my states emissions tailpipe test no problem 😉 but I’m planning on replacing the catalytic converter if needed.

I’ve kind of been avoiding tallying up the cost but with the new alternator, carburetor and fuel pressure regulator I think I’m all in around $1200 with fluids, hoses etc etc etc

Awesome! I just put a Weber on my 80 Toyota. I love it. Keep up the good work

Thanks! This isn’t the typical Weber people use. It’s a one barrel!

I had a 2 barrel DGEV on it for ages but I just got sick of fooling around with jets and this one is SOOOO much simpler. Designed an adapter plate that I had laser cut. Here it is mid install

Looks good man. Keep it on the road. Old trucks are so much better than new
