8.1L Vortec Swap in 76 K10 SWB - Fuel Tank(s)

[Shtudwn]

Hello Everyone.

Its been a while. Once my K20 Camper Special was stolen I floundered a bit. I have since purchased a 76 K10 Short Box with the hopes of utilizing the 8.1L and the Allison Trans.

The K10 lost a driveline at some point and tore out the fuel tanks. The owner then replaced one of them with a roughly fabricated single aluminum tank. With my plans of swapping the 8.1L into the truck what are my best options for a fuel tank? Do i buy two short box tanks? Do I try to retrofit an 8.1L tank into the 76? Do I go with a single tank?

Thoughts?

Thank you.

Dan
