My current setup is a 350 with a holley 670 carb on an edelbrock intake with a mild cam. Was thinking about either a holley or a fi tech efi.

Is it just a strait swap or should I look into upgrading other things while I am doing this (intake, cam)

The car was originally a 305 tpi so it does still have the fuel pump for a fuel injection setup.

Thanks for any suggestions/tips

 

​​​​​​​Kinda depends on what's there now.

 

Do you have an in tank pump? I assume you don't w a aftermarket carb setup. But everyone knows how assumptions go. If your happy w your power then just do the efi swap. If not, you should do it all at once. The fitech stuff is pretty lacking. I have an old bronco that came w an go efi system. The interface is pretty lack luster and the tuning is just so-so. Ive had 2 edelbrock pro flow systems and they're far better in every way. The holley systems are in between. Regardless of the EFI system, you'll need a new fuel system. Either an in tank pump w filters and a regulator w a return or a sump system. All the systems either run on 43 or 58 psi. The systems that are a 4 barrel looking TB w injectors in it are OK(ish). The edelbrock multi port systems run awesome. All of these systems are tight under the hood. The pro flow systems w multi port and a carb style TB didn't fit under my stock TA hood. But it ran awesome. Now I have a pro flow XT that fits under my stock TA hood. The pro flow is more money than the others but comes w an ignition system and the others don't, plus it runs better. This winter I'm pulling the fitech off my bronco and installing a pro flow on the 302.

this is my pro flo xt system. I had it running for 2-3 yrs before the blower and it was great. It was also easy to upgrade to forced induction.

 

A Holley sniper is a direct bolt on and could be done in a long afternoon if your fuel pump can do 60 psi, or i'm not sure if the sniper will work at 42, a short weekend if you do it the right way with the hyperspark distributor and CDI. That will get you 98% of the way there. Port injection would be 99, and sequential would be 100 but now youre looking at serious investment. I run an 8 injector super sniper (old, discontinued) and its so bolt on that the machine shop was able to dyno the engine with their house 650 holley and a letter brand HEI i got off amazon. If i had to do it again, I would have gone sequential, but the outlay was north of $5k vs $1300 for the sniper. There's tons of support for tuning the holley too, which is probably more important than the product itself.
