engine swap 350 to 454

[edgoodell@gmail.com]

I have a '79 Suburban that someone before me swapped the original 454 for a 350. I want to put a 454 back (as it should be) and want to put a 454 with TBI. It looks like the only major modification is to install an electric fuel pump to support the TBI. Am I missing anything in that assumption? Anybody have experience with this swap. I'm thinking I can go up through about '89 or so and pick from 2500/3500 pickups and Suburbans. We have a U Pick U Pay here in Denver that appears to be a good source at exceptionally reasonable prices. Like to hear anyones thoughts!

You may also want to get the fuel tank from a TBI suburban. It will be a baffled tank and will reduce the possibility of starving the pump in the event of fuel slosh(or just always keep above 1/4 tank).
May as well grab all the wiring you need while you are at it, unless your plan was to go new aftermarket.

TBI has a return line, doesn't it?
