305 swap to a 350 tbi

I have a 80 el camino with a 305 engine. I want to swap it for a 350 tbi engine out of a 87 truck. I need help with the swap. I know I need a in tank fuel pump, but can I get away with using a in line pump in shed. I also swapping the 350 tranny for the 700r4 out the same donor truck. what mods if any do I need to make; guages, raditaor, fuel pump, wire harness, etc. Or is a tbi worth the effort.

Hi, Not in my opinion,too much involved and not enough gain to warant all the work envolved, just use the intake off your 305 and stay with the carb. Slim
