For a winter upgrade, decided to do dual walbro 450 pumps. I was initially going to use dual 340 pumps but wanted to use e85 rated pumps and I have had great luck with the walbro 450. First off, there is no way two of these will fit through the stock opening in the tank so I am going to modify an n/a tank I have laying around. For the sender, I bought a dynamic fuel pump module from ricks restomod tanks with an integrated fuel bucket, so there's no need for in-tank baffling.
More updates coming. I need to weld a late model GM fuel pump flange on to the n/a tank yet.

Update:
The fuel tank parts showed up and I began mocking up the fuel pump flange onto the new tank. Its all tacked up. Now, I need to find a local tig welder..
New Spectra GM307A tank
stainless fuel pump flange (same flange as late model gm vehicles. Can use use 5th gen camaro or cts-v pump modules)
Big hole
Wrapped the plate with 16 gauge steel to recess it 1-1/4"
All tack welded up
Added bungs for a fuel vent and also vented the fuel neck to help with filling.

Just finished up the tank. I ended up resealing the tank's interior with por-15 tank sealer to prevent the welds from rusting from the inside out and sprayed the outside with semi gloss black. Also, the sender has seperate outlets for each pump so I wyed them together with stainless tubing and a fragola wye fitting.
The wiring in the car still needs to be done but I'll wait for it to warm up. The plan is to run a 10 gauge feed to each pump and also trigger the second pump via a hobbs switch at 7-12 psi.

Looking good.
I just used some POR-15 to seal the inside of the quarter panels on my last little project. From what I read, the stuff works great at preventing rust.

The exhaust runs all the way out behind the tires. After the downpipe, near the trans crossmember, the exhaust bolts up to a bolt-in pypes dual 2.5 exhaust kit. The car is extremely quiet.
There is also a GN1 3.5" cutout installed.
