LT1 swap

[MARKDTN]

I have not done an LT1 but I have done TPI. I used TBI S10 Blazer lines (SWB truck) and then hydraulic unions to splice to the fuel lines up front that came with the TPI. For an LT1 you could do simliar, but you will have to adapt to get to the LT1 lines. Just don't use a brass union for natural gas; they are not rated for the pressure. For the throttle cable, I would try B-body Impala/Caprice, it should be close. I used the Blazer tank with a TPI pump. I think you could do the same but with a B-body LT1 pump.
