Truck newbie here. Need help w/EFI tanks

[theneiltor]

Hello fellas,

I'm all new to this truck thingy. I've built first gen camaros and now I'm building IROC camaros. Needed a truck and decided to get something "interesting". Got a 1965 Chevy C20. She's got a 350 out of a 1974 A body car and the rest is original drivetrain far as I can tell. I plan to transplant a 1989 350 TPI from an IROC. So that means a fuel injection gas tank. I've searched many threads about EFI swaps but nobody seems to talk much about the tanks. Who's got comments on which ones are best. Should I go with top filler tube or side. I'd really like side but I can't seem to find any pics of what that looks like.

Thanks all
