Not true. I've had 3 carter pumps fail all the same way. THe first 2 still kept giving me fuel so I could cruise easily but it would bog when I gave it the beans had less than 3 psi. The last one just up and died. All of them failed at the swage point of the fuel pump arm. It pulled right out of the swage. I believe I still have all the broken ones in a box of garbage parts. And theres no kool aid for most of us. I never liked tuning a Holley, they have to be pulled apart and gas gets every where. Edelbrocks are easy to tune and the fuel stay in it when you pull the needles but will drain into the engine when you pull the jets. Quadrajet is the worst of the 3 to tune as it has to come apart, but the spreadbore is the best for an all around good carb for economy while cruising, Im getting 17 mpg around town, and its a riot when you open the secondaires. LOts of fuel and power when its tuned correctly and the motor can use it. JKippin still cant believe ive had a "quadrabog" for going on 3 years this summer. And I still plan on going to EFI myself in the future

all of this is quarter to half throttle

 

Ok, I am going to fall on the sword and present the benefits of the EFI system. I recently went through a restomod of my 68 C3. This included an engine swap to a BPE 632. The engine was purchased and originally dyno tested with a 1250 cfm Holley Dominator. It’s a bit unruly with around .700 of camshaft lift. The motor ran great at wide open throttle, but suffered in cruising drivability. After much consternation I purchased a Holley Super Sniper EFI system. I did have to rework the fuel system for high pressure, but a new tank was not required. We added 2 in the tank pumps. I already had a 6AL MSD box and MSD electronic distributor.
I too was apprehensive, but this system has proven to be an excellent choice. The vehicle can not be driven for several weeks and I literally reach in the vehicle, twist the key and she roars to life every time. Drivability is excellent- the EFI has given the beast some street manners and we actually picked up about 45 hp after going to the EFI also (840 to 885)! Tuning is performed via laptop or by the in car screen. There are many features of the system beyond general drivability, such as fan controllers, AC compensation, timing control, fuel curves, Idle control, data logging, launch controllers, 2 step and rev limiters, just to name a few.
I am an old school hot rod guy, but if this mod allows me more enjoyment from my toy, I feel that my goal has been achieved.
Only my two cents!

 

Reality check!

While you may have success installing an EFI conversion doesn't mean someone else with unknown skills would be successful or even leave the car disabled and a piece of garage furniture. You boast all the modifications performed but fail to mention the cost and labor hours required. Most shops would welcome performing an EFI conversion with the business generated with the expensive parts and labor.

But the OP said his priority is reliability and not expense so then it becomes a matter of finding a shop that can perform a successful conversion without turning the car into a quirky crippled driver with a hacked EFI installation. Jobbing out this much work could easily reach $5000 in parts and labor. Could a carb and fuel pump replacement cost $1000 even with a new tune and carb adjust? I don't think so.

 

We have a winner! Fixing everything with OEM+ components (new HEI distributor with tach drive, and a reserve fund for a new carb, whatever you are most comfortable tuning) should barely crack $1K, plus labor. The OP should learn to adjust the carb and timing himself, by reading the tuning papers, watching Youtube videos, and reading books. I've been blessed by having two unmolested Q-Jets on my cars, but it isn't rocket science.

Full disclosure: I'd love to put EFI on one of my cars. But it would be a complete DIY project, fun for the whole family. But in the meantime, I have two Q-Jet/HEI cars that can sit for months, then start and drive reliably after 5-10 seconds of cranking.

 

Sorry I disappeared for a little bit. Work got busy. I want to thank everyone for the valuable posts, suggestions, and information you have shared. I have read thru everything you guys have said. I think I was a little quick to jump on someone else’s plan to inject my car. As some pointed out, there’s tons of carbed vehicles out there running everyday. The mechanic came to my house to see the issue first hand. He admitted something is wrong with the carb, but didn’t go into details. He has become busy and unresponsive (should have seen that coming). The summer is half over and my car hasn’t left the garage. I get the worst feeling seeing it sit in the garage without use.

I think I have come to realization that fixing what’s there is probably the best thing to do. Now the question becomes what carb do I replace mine with. Is it a simple swap, old vs new, or is there adjusting and setting up needed to be done With a new carb?

 

If you haven’t priced a carb lately your going to be surprised...I would look at rebuilding it first

 

You just need to find the right shop.

 

Nice video but, in 3 minutes and 45 seconds I thought you would have stepped on the gas somewhere. Just sayin.
