94 K1500 TBI / Vortec head swap - Cam question

[Roadknee]

Thanks Roadknee. Does the EP377 fit into the stock TBI sending unit or will I need to make some modifications? What about the EP381?

The EP377 is the '95 454 TBI pump rated 30 psi. The EP381 is the vortec 350 pump rated around 60 psi. I prefer the 377 because it will be operating at closer to its rated pressure. Either will drop into the stock truck sending unit.
