Your good, I didn't mean it to sound the way it did either lol to put it this way. I'm starting college this fall and am on a fairly limited budget. And want something that I can go have fun with and still drive. Only reason for building a 408 is that i already have a block and getting the crank from a buddy that built a 408 a few years ago

fuel injection:
Intake $700
Tb $250
Injectors $300
Tune $500
Wideband o2 $300

Carbureted motor:
Intake $300
Carb $400
Stuff to make it all work, maybe another couple hundred.

 

An AEM wideband is like $165. 4bbl M1s can be had all day long for sub $350. Modified injectors from FIC (I've been using a set for years) for $240. Over $500 less than you thought.

With a carb you will need a new fuel system and distributor at least.

 

Fuel system is fine and I'm gettin a msd system anyway

 

Well good luck pumping 49PSI into a carb.

 

That's what return style regulators were invented for.

Using a non-return regulator would smoke the pump in relatively short order.

 

There are two good regulators to step down EFI pressure to carb, I have the returnless type. It will not smoke the pump, because it is still passing the same volume as a EFI system, thus providing the same amount of cooling. In other words, it is acting just like a fuel rail would, taking the same amount of fuel, leaving the same fuel pressure in the line... I have approx. 2K on my setup with no problems.

However, I would recommend a return type for anyone trying to do carb. It is much easier and more precise to use than a returnless.

 

Your prices are a little high for the EFI stuff. But the BIG ONE is that you left out a lot of stuff you're going to have to buy for the carb. New distributor, linkage, external voltage regulator and other things I'm sure I'm forgetting now.


I understand being on a limited budget and am not trying to be an ***. I hope it all works out for you. EFI or Carbed have fun with the 408.

 

The reason I didn't put distributor in is because either way it goes it's getting a msd distributor and coil

 

I don't think you can run the MSD distributor if you keep the EFI. If you can I sure would like to know how.

 

fixed. converting to carb is not cheap. there is also other thing i may be missing. unless your truck is carbed it is a waste of money coverting. it will also lower the resale value of the truck if you ever need to sell it.
