Question about 540 CI Dart Motor

[Xpock182]

I really appreciate all the advice and help guys. This has helped me tremendously when deciding on where to go from here.

I have decided to take it to a local engine builder and have them do a full inspection with specific instructions to pay attention to the things that you all listed (Fuel Pump, Fuel lines, Fuel Filter, Spark Plugs, Accelerator pump, Entire fuel system, etc...)

Also these guys should be able to tell me a lot more about my motor and what it has. Fortunately they have a dyno so I will be sure to post pictures and results for you all.

Eventually we will find out what all this car has and get her running like she should be.


At this stage I am waiting for the results of their inspection then I plan on making the decision between a new Carb and mani or just pulling the trigger on EFI.


I plan on driving this car a lot, 2500 miles a year or more. So I want it to be enjoyable. Also I intend on moving to the interior once she is running smooth.

If you can afford it, you should consider doing the efi while it is in the shop. I would also consider porting the heads and new intake while the engine is apart. My BBC 477 runs a ported 454r intake and is getting a FAST 2.0 XFI. You have a Beautiful Car!

What makes you recommend Fast 2.0 XFI over some of the other systems out there such as the Holley EFI?

My engine dyno'd best with a ported 454r intake manifold, and the 2.0 bolts directly like a carb. I mentioned head porting because Dart heads respond well to minor porting. If you port match a good intake manifold, you either have to have it tapped for multiport, or go with a 2.0. Most of the shelf multiport kits are not going to come with a particularly good intake. They are designed to fit under most hoods. You have a raised hood and clearance for just about any intake manifold. An Edlebrock Victor Jr is around $300, a Profiler Sniper Jr is $385. Porting of either is around $400. I mentioned these two as they are potentially good candidates for a 540.

Let's say you have a BBC 540 crate motor with 650hp. If you make a few tweaks, it can easily make 800. Port match the heads with a good intake, and get somebody like Chris Straub to do your cam and you are there. Yes hydraulic roller, smooth idle in traffic, etc. Top it off with efi and your set. Im getting jealous just thinking about it, lol.
