Howdy Guys,
Well, as the topic says, I have decided to embark on a project to swap the 350 chev in my boat out for an LS1.
Ive already identified a few parts im going to need to make it happen.
The exhaust manifolds will need to be swapped. The exhaust manifolds have a seperatre water jacket running through them to keep them cool. Because the heads are different between the LS1 and the 350 chev (LT1) the exhaust manifolds dont fit. Bloody things cost $800 just for the headers!.
The sump will also need to be modified. Given that the engine has to sit in the boat backwards (intake to the rear) the front (or rear in this case) of the sump sits too low meaning the motor wont sit in all the way.
I think ill also need to get a new bell housing (which is actually bolted to where the timing gear goes!), given that the timing case on the LT1 and the LS1 are different as well.
Here's a question im throwing out there.........One of the things im trying to find out is what I can do about the loom. I already have a PCM (ill use the road runner for a while), and obviously because its pretty much bare bones in the boat, i dont need all the other bells and whistles that the loom can provide.
Can anyone shed any light on wether or not i might have any options for a "cut down" version of a wiring loom purely just to handle running the motor??. Better still, does anyone have one they might want to part with for a reasonable price for the project??. (bit of a classified there).
Anyway, all in all it should be a good fun project. I also have an LS1 twin turbo kit under the house that ive been sitting on for a while. Im thinking of maybe trying to fit it up to the boat as well. ....... but one step at a time me thinks.
I have an LS1 motor with about 50,000 ks on it on an engine stand in the garage, and a 220 200 518 518 112 cam. In other words, im starting to gather all my parts!
Id be really interested to hear anyones ideas, comments, input, slander, etc......
Thanks for reading.
