Gutting out my Tahoe for my El Camino Hello all I am new to the board. I have a few questions. I am going to began a new project which will be a 84 el camino and I will be taking my Tahoe that is totaled and snatching out my 5.3 ls327.
My questions: Keep in mind I have a complete tahoe with harness, cpu etc etc.
-I am not sure which would be best, carb or FI (fuel injectors). Which is most simple and less cost effective? This will not be a daily driver or a big time track car. Just want something that sounds good but runs good as well (just in case)
-If I go with the carb, will I need my cpu still (swapping tranny with 700r4)?
-If I go with the FI, will I need to change my tank and fuel system on my elco?
I will be working inside out on my engine. so from the crank up I will rebuild. Just trying to see which is best for me and my elky.
any help, pics advice would be appreciated much. Thanks all in advance!

I dont think you can run a strait carb on these cars, typically you have to keep the fuel injectors and run a TB on top of a carb style setup. I could be wrong but your best bet is to stay fuel injected.
you still need some doner parts off another car, try to find a F-body and get a ls1 intake, TB, harness, Computer, oil pan and accessory brackets, maybe the water pump too.
you can use the harness and computer off the taho but ive heard there not as tunable as a true LS1 ecm, I am not sure on this either though.
you probably wont need to change the tank but you will need a eletric fuel pump

We have an entire subforum on carb'd LS motors. They run real good with carbs. Check out the carb'd section for lots of posts with all the pros and cons of EFI vs. Carb.
Unless your camino already has an electric fuel pump then you will need to modify parts of your fuel system either way. EFI will need a high pressure pump and some type of return line. EFI should also have baffled or sumped tank to keep from uncovering the fuel inlet under hard corners and full throttle. Carbs have a bit of fuel in the bowls so they aren't as sensitive to that as EFI. But for a cruiser you can get away with a non-baffled or sumped tank with EFI. Just keep over half a tank and don't beat on it unless you do.
Spend a bit of time searching carb vs. EFI in the carb'd section. Good opinions in there.

It depends on the Tahoe motor which MSD you will need . There are several threads here that tell what you need to check . There is one setup for a 24t reluctor and another for a 58t reluctor . The 6010 is for the earlier motors , the newer motors use the 6012 . Good Luck with the project , it sounds like it will be pretty cool .

This is from a 2001 tahoe (lm7). I just checked and its for the 6010 should work fine. Thanks much!

I just ordered the same setup for my jetboat project from Amazon , $556 with free two day shipping . If you watch close here they do come up for sale used , but I didn't want to hold up my project waiting for used parts to come up for sale .
