Mechanical fuel pump on a roller cammed 360?

I think you’ll be fine with your friends ‘89 cam Kern for all the points and reasons listed above.

I have the magnum motor so HAD to use an electric fuel pump. I didn’t necessarily want to to buy and EFI tank and install kit with bypass regulator BUT did and am actually kind of glad now as if I ever want to explore a tbi based (or other) fuel injection (aka sniper or fi-tech etc) I can with out having to worry about buying the pump/tank etc at that time reducing the out of pocket shock…. Will only have to pay for the tbi unit.

Only reason why I mention this is because as a hot rodder we seem to get bored and like to try new **** over time so perhaps this is something you may want to consider for yourself. And if you did then the fuel pump drive eccentric accommodations of a cam would be a moot point and you could choose whichever cam you want right now.

One big plus of having the electric pump set up in my carbureted magnum is immediate starts even after sitting for a long time and also seems to start better when hot too. The prime of an electric setup is nice. The bypass regulator and return system keeps the fuel cooler too….

Big down side of the internal tank pump set up is cost though…. When I did it I had to buy a new tank as mine was leaking and bashed up so the upgrade cost to go from regular to EFI tank wasn’t that much more and it eliminated the cost of a hi-po mechanical pump too. If I had a good tank at the time I may have opted for the inferior external electric pump and el cheapador Holley regulator….

I wonder if tbi fuel injection systems decrease emissions too? Not that I care too much but you being in California might end up getting screwed if they start demanding minimum emissions requirements. Not sure maybe they already do? I don’t know anything about that, in alberta we don’t have smog testing and requirements like I hear of and some states do?

I need to win the lotto! lol.

good luck with your 360 swap!
