I currently have a ls1 5.3 in my truck. I was thinking maybe putting everything from it onto a ls1 5.7. The cam will probably be a little small, but I'll upgrade that later. I'll have to get the combustion chambers on the heads cut to fit also, i think.?? My question is would the alternater, power steering pump bracket, A.C., etc... bolt up like it is now or would I have to custom make a bracket? I'm also wondering if the converter would fit or have to change the drive plate? Any info would help!!

 

i always heard it was a direct swap

 

Yes if you use all your truck accesories you will have an easy swap. I have been there and done that. PM me if you need further info

 

Would you have to swap out the PCM or not? And if so how hard will it be to do that?

 

I am currently running my stick 5.3 pcm and it runs just fine. I know with a tune it will run allot better.
