Looks like we are going with Holley Sniper, ignition, distributor yata yata intake, the works. Get on it after Indy.

What was the cost on that, if you don't mind sharing?

I don't have any experience with the newer systems.
But I went to try and change a stock car over to efi, just to make it more reliable.
I have no intentions of hotrodding it, so I think we are in a similar boat.
I did go on the cheap, and overall still spent about the same amount as one of the kits out now.

Here are a few things I learned that might help you decide.

If you are not trying to get every single HP out of your build, spark control is a waste of time and money.
Just one extra thing to tinker with, that a regular vacuum advance distributor(still electronic) would do just fine.

A surge tank is another way to go instead of an efi gas tank, or having a custom tank built or cutting up your existing one.
However, it creates complexity. In my case, there is no mechanical carb pump to feed it, and it requires I have 2 electric pumps instead of just 1.
While there are other choices like the holley hydromat(which recommends replacment every 10 years,) the aeromotive efi pump kit with the foam, or having a sump or baffels welded into your existing tank, I think I would go for the custom tank built for efi instead.

There are several systems out there.
Each with its own unique set of issues. however for a straight stock application, I don't really think you can go wrong with any of them.
you really have to look at support for your decision.
How likely is that company going to be around in 10 years when some part fails.
I always assume the worst. So I look to see how common the replacable parts are going to be.
What o2 sensor do they need you to have. Is it proprietary, or is it a common off the shelf one.
what fuel pump is it?
did they do some odd connector or is it the standard for that part?
The only thing you have to worry about after that is the ecu.

Now if you read the board regularly, you will see people here are a bit fickle.
Each time a new efi product comes out, it is the best. Till it isn't.

Today it is holley, 6 months ago it was Fi tech. 6 months before that it was FAST Efi.

It kind of goes in cycles.
As more people use them, more problems come up.
But if you pay attention, it is for the people doing more than stock stuff generally, not just the plain swap from a carb.

I have seen the same for what I did. As you add more things the efi computer needs to do, it just adds complexity for more things to not work together, or fail.

My recommendation is to make it as simple as possible. Keep with 1 system of stuff, with good support in case you need it.
Sometimes simple means spending a bit to make it simple.
So you buy the efi tank or mod yours.
you get the returnless system if they make it. or create a short return run like corvettes do.

Good luck.

The engine has a new MSD plug and play complete ignition system. Looking at videos, can I make distributor a lockout and use the adjustable rotor for the EFI? Or just get the Holley distributor. I can move the MSD system over to Lemon race car. Also, there is a small vent return line to tank from a canister on radiator support. I doubt it would be large enough for the return line some systems require. The MSD Atomic says it is single fuel line, any users of that system here. Thanks again

This years altitude change had a lot of us sea level guys working on carbs in the evening AFTER the 2 hour viewing for the crowds. Just looking for something to return our PBR time. LOL

PS Wrong thread but the Ugly Stick Hemi Coronet with the Pro System carb required nothing and ran perfect!!! For sale on Hemmings. Jake

I also got a roll of 3/8" tubing which was $19.I plan to use the existing mechanical pump line as the return. I'm sure there will be a bunch of fittings and clamps involved with the fuel lines which add up quick.

When I put the parts in my online cart a few months ago, the tank was listed for $593 but was happy to see it come back down to where it was originally at $569. Prices are essentially the same everywhere.
