1986 c10 thinking about swapping an erod ls3

[donw1986]

how much extra work will it be to hookup my a/c , power steering ,etc or will it just bolt up also what about the gauge cluster

[donw1986]

also will i be able to still use both of my fuel tanks

[mongocanfly]

Well its not going to just "fit"..you will have to do some modification type work.along with a ecm and wiring harness and all the accessories, dbw gas pedal or swap to bdc.. you will need a truck style oil pan to start with. hooker now makes a header, motor mount and trans crossmember package.check the post just below yours...you will need custom hoses for your ac,, power steering should hookup ok,, mine did,, not sure what type gauges you have..I went with mechanical gauges on mine,they make a metric to standard gauge adapter kit,I don't trust idiot lights..you can probably use both tanks but you will need a electric fuel pump and regulator setup for the truck.I used walbro 255 and a corvette style filter regulator setup. Or go with in tank fuel pump..

Would the oil pan off of my 350 thats in the truck fit on the LS 3 also wondering about trans if my turbo 400 would would work with the LS 3 or better off with a erod connect and cruise package motor and tranny 4l65e

[donw1986]

Or how about the LC9 motor

[mongocanfly]

That's a no go on the 350 oil pan..2 completely different engines..the turbo 400 will work with the right adapters..the 4l65 will work if you want overdrive..the lc9 would be a good choice but you will face the same obstacles with all the ls engines,, you just have to decide which one..

Thanks for all the info

Your swap wouldn't be any different than any other 73-87 square body, only difference is that you have to run all the emissions stuff, but if your getting a 5.3 LC9 EROD you have nothing to worry about, it would come with everything you need to be emissions legal.

[donw1986]

ok thanks yeah that is why i was going with the erod for the emmisions package just wsnt sure about all the other details i would encounter like mounting the a/c compressorand power steering and if i would need to change out the gauge cluster to be compatible with the more modern elctronics

[Clyde65]

I believe there are mounts for an A6 compressor ( I think that is right) and all you really need to do is set it up so the AC is basically stand alone- like with an aftermarket AC system would be set up.
