It came with a Holley and dual 3-into-1 headers and dual exhaust. I suppose it was a bit more powerful, but all of it was old. The Holley caused the motor to stall exactly twice in exactly the two most precarious spots we ever got ourselves into. It threatened to stall a bunch of other times. The header flanges were a mass of embarassing, noisy leaks by the time I took them off and sold them for beer money.
All the smart money on the board is on rebuilt original Aisin carbs. Mr. PO saved mine for me nicely. I met and wheeled with Mark A. of
Marks Off Road Home Page at Surf & Turf, so I gave him the nod and sent my carb down when we got home.
It wasn't free, but the result is very nice.
This is the first set of hard lines that I bent up. I made a few more sets, kept the best set and sold the rest.
In parallel, I had the rusty original Thermal Reactor exhaust manifold sand blasted. This revealed a few little cracks, which I patched with a Permatex product and otherwise ignored. Then I painted it with Aussie Nu-cast VHT Manifold Coating Paint. It's holding up ok so far.
After another bout of brake issues and finally getting them figured out, I got it to the muffler shop. They reused one of the dual pipes, and its two cherry bomb mufflers. I had them take the 2nd header flange and bolt it to the first, then weld it all up to a SOR-bought exhaust manifold flange. This way I have a 2' removable section of pipe just behind the exhaust manifold so I can get it out of the way if I need.
