LS-carb or fuel injected?????

[NOPANTS68]

I've done a couple LS engines with carbs and have had great results. It's super simple and the MSD controller is easier to use than a phone. As far as the fuel changes, hard starting, etc. etc.- I don't know about all of that. In fact, my results say otherwise. My 3200 lb. Nova ran mid 11s all day, any day with a T56 and 3.73s with a used LS1, cam, a 750HP, and hand ported 853s. No big deal, plus it looked awesome and different. I think I'm pretty good with a carb, so it's my preference. Go with what you know, but at the end of the day you can't convince me the EFI looks better than a Victor and a carb. BTW, in most cases LS engines make substantially more peak power than the plastic EFI setups.

dude if you want it carbed then do it, when I popped the motor on my car, a carb LS made sense, already had a kick azz fuel system and a great carb, so I swapped in the LS dropped on an edelbrock intake and the MSD 6010 box (3 wires to hook up!, power, ground, tach) and I drive my car everywhere with the same fuel system(holley HP Billet 12-890), transmission(t-rex 4 speed), drive-line(8.5-10 bolt with detroit tru-track), everything I had before but now I get 19 miles to the gallon and still kick butt on the track

The way I see it, if you gonna do an LS and have the intake go all the way with it. A PCM program, Walbro pump and a C5 regulator to me is cheaper than a carb ,fuel pump and ignition controller. If your getting a long block with no PCM, Harness or intake then yeah, its the easy route.

I just don't get the argument for cost when talking carb or EFI. If you shop smart and have some wiring skills you can do EFI for cheap.

I agree with you -- but you're also making some big assumptions. Most people are fine "mechanically" but when it comes to wiring -- they're nightmares.

So yes - it can be done inexpensively IF you know what you want - and how to put all the parts and pieces together to make the system work. That's usually not the first time guy.
