LS Swap questions

[danpomeroy]

Hello All,

I am running late with my build but I am 2 paychecks away!!

I am going to be ordering an engine from Spaldings because I want very low miles and the selection here where I live sucks. I am currently thinking a 5.3 and a 4L60E. I can get pretty low miles, good gas mileage, and easy setup.

Anyhow, I have been doing some research and have a couple quick questions. First though I habe a '69 C10 2wd. It has a 350/350 in it now.

First question involves drive by wire. Should I get the pedal from Spaldings when I get the motor or is it better to order one from someplace else? Basically, is one better than the other.

Second, if I am using factory gauges, what do I need to get to make the speedo work?

Third, what would be the best header for that? I would love the cheapest ones possible, even factory if that would work.

Finally, for fuel I am going to keep the in cab tank (for now) so I am going to go with external fuel pump and corvette filter. Since it's 1 line to the engine, do I have to plug off the return line?

I apologize if these are "dumb" questions but I couldn't find definitive answers. If I missed it and there are other posts with the answers then please point me that direction. Also, if there is a decent guide out there I'd love to be pointed in that direction.

Thank you in advance for all the help I will need.

Best bet it to get the pedal and TAC with the motor. You can get the pedal and TAC elsewhere, but it is imperative all things match year wise and you have more variables such as adjustable pedals you could run into.

A cable X box will make the speedo work, or one of the members on here posted how to make your speedo electronic.

Headers, I and others have had good luck with Trail Blazer SS (TBSS) manifolds.

Return line from the vette filter must run back to the tank. Hope this helps and

Thank you for the responses. I have been really busy.

Just ordered my motor. Getting an all Aluminum 5.3 Crate and a 4L60E. I think this should do the trick.

I run one of these on my Suburban for my mechanical speedo http://www.speedscenewiring.com/ssw_...products_id=12 Didnt cost that much 7 years ago, But it has lasted 7 years with NO problems, Buying a electric drive box or a one-off electric speedo head is a problem waiting to happen.

With DBW its best to get the pedal, tac module, computer, and throttle body all from the same vehicle. In your case, if they have the matched set it would be best to get it all at once. You don't really have the luxury of "best pedal"...with dbw it either works or it doesn't. (there are a couple aftermarket ones, but I know little of their functionality.

Second, if I am using factory gauges, what do I need to get to make the speedo work?
Its a digital output, and you need an analog input. There is a product called (iirc) X-drive, than lets you run a cable driven speedo off of your current setup.

Third, what would be the best header for that? I would love the cheapest ones possible, even factory if that would work.
Trailblazer SS manifolds are a good cast manifold that squeeze into almost anything.

Also check out ls1 tech for the speedo someone on there is working on speedo set up I think it's called make that speedo work its for ls swap To use my stock speedo.They are in the test mode of this unit and it seems to be holding up well. I'm watching closely and will probably be getting one for my 69 ls conversion that I'm currently working on. On the return line I drilled through the sending unit and bent a hard line following the same angles of the pickup and terminated about an inch and a half above the pickup sock. Walbro external pump and vette filter/regulator is what I used.
