EFI - new build

Looking to purchase a long block/T5 for my 65 rebuild, moving from a I6 to v8. Eventually, I see installing EFI, but I'm really nervous on how much change I have occurring. The other side of my mind says I'm wasting a lot of cash on a new carb, points, etc., that I'll pull off when I install a EFI unit. Does anyone have good analysis on or thoughts on installing the EFI on my initial set up versus getting the car back on the road first? Thoughts?

Well points and all that aren't that much and a carb you can re sell after a swap. So you'll be able to make some money back. It also depends on the how long till you go EFI Or just upgrade to all the parts that are comparable with EFI systems so you aren't wasting money. You could also rebuild your carb instead of buying a new one

Wow great question. what are you asking? Should you go EFI? Or not?

I myself am staying with a standard carb. What are you trying to do with your car?

Don't forget to add an O2 bung in your exhaust system.

The downsides to doing EFI will be, some additional electrical work, and tuning, whereas, a carburetor, you can tune yourself, without any expensive software. And you can use a HEI distributor, which are very easy to learn to tune.
Swapping an existing fuel injection system from a car such as a Fox Mustang isn't to difficult but there is definitely more involved with it (Electrical, fuel system, etc.) than doing a carbed-engine swap.

What kind of EFI system are you thinking about?

As you can see, the car is gutted! I'm removing all the I6 suspension engine tranny.... And moving on. My plan is a maybe not daily driver, but a lot of road time. This car and I have been together since 85. I'm looking at a 302 long block from Jasper Eng. mod driveline 5speed, currie rest end. So, the idea is " has someone else ran the numbers on the real cost of EFI sitting in my position where I'm needing to purchase all the parts either way I go...does that make sense?

Mine is sitting the same way. I started out with a 289 and will keep it. I will upgrade the cam heads and intake to make it have a little more HP. As for changing over to EFI I don't think it is worth the extra cash to me. So I will going back to a carb.

302 EFI System - Electronic Fuel Injection

Atomic EFI - Atomic makes EFI easier than easy

Check with Summit Racing to see what they offer in the EFI line.

The good thing about efi is that it's reliable for the most part where as carbs the need adjusting everyone and then. So you said not a dd but a high milage car so if you won't mind that extra work then I'd say stick with carb

Plus with a carb, there is the excitement of wondering if it will actually turn over when you crank it

And since it's not a dd, you don't have to freak out about missing work if it doesn't
