i have a nieghbor getting ready to put in asc motor in his 07 3500 monte like mine what will there be there ahead of him when he starts the project i know he needs the pcm for it the wireing the compurter for it. will he need different type of engine mounts and tranny mounts the sc what he told me he reworked. alot of things in the motor the tranny is reworked with better gears but what is ahead of him. i am interested on doing it to mine swapping out my 3500 to a sc motorbut not yet

 

If he is getting ready to do it, then why don't you ask him?

If its anything like the other wbodys- it all simply bolts in with stock engine/trans mounts. The problem with the new montes is the wiring- I don't know if you can just use an 05 harness from a s/c ss or not (I'm betting it still needs more electrical work than that though).

 

he isnt sure what else he needs he is looking in to what extra he needs for the swap so all he will need to do do is drop it in i think he allready knows that the engin mounts will work but i think he is doing home work befor drop in but i will like to know as well i just wanted to know if any one was thinking the same thing with the lt 07 that is the 3500 but i was guessing the wires that come from the computer to the motor was bifferent what i mean is the conectors and the program was different as well i dont know there is a computer for the motor that is the sc is needed for the higher air fuel mix is needed i believe so but is there any thing i will need to know as well

 

I don't understand what you're talking about- higher fuel mix, and all that crap. Ideal normal (non PE) stoich fuel mix is 14.7 on any gasoline engine.

Of course the wires are different between the 3800 s/c and a 3500, they're two totally different engines- you need to use a 3800 (na w/ swap adaptor or sc) wiring harness, and a 3800 pcm.


As for the rest of it, you type like an idiot and I can't make sense of half of it, so maybe if you really want people to help you- you'll take the extra 30 seconds to add some punctuation and line spacing next time you make a post so people can actually figure out what you want.
