bowtie ss Posted July 16, 2009 Report Share Posted July 16, 2009 (edited) I have been wondering if it is possible to put a ls7 427 in a ss silverado. I have herd from other people it will fit but i dont know if you could get the proper wiring harness. If you have any knowledge about this please let me know.

bowtie ss Posted July 16, 2009 Author Report Share Posted July 16, 2009 what would be the easiest way to make 500 Hp Quote Link to comment Share on other sites More sharing options...
zeake Posted July 16, 2009 Report Share Posted July 16, 2009 The shortest answer is cash. Plain and simple. Quote Link to comment Share on other sites More sharing options...
cadowns Posted July 16, 2009 Report Share Posted July 16, 2009 The LS7 is a DRY sump oil system. A regular LS engine is Wet. There is a lot of additional concerns when making this swap. You have a lot of other options now when is comes to making 500 hp. Start by searching different sites, like LS1Tech.com or performancetrucks.net. Good luck on a conversion CD Quote Link to comment Share on other sites More sharing options...
bowtie ss Posted July 16, 2009 Author Report Share Posted July 16, 2009 see i have a 502 crate engine but its to heavy so i was looking at a 427 then putting a kenne bell twin screw but i dont know any more, I also had ideas of changing the cam and running new heads but who knowes. LOL I have a bet with my cousin that my truck will beat his srt8 jeep haha and its a 1000 dollar bet Quote Link to comment Share on other sites More sharing options...

I think Mean05 is the one to ask about that. Personally, I dont like the STS because it is so tempermental. Sure, once its dialed in and everything works right, it produces good power, but for some reason, I seem to read a lot of threads on a lot of boards about people always working on their STS system. I threw my magnacharger on with the other supporting stuff I mentioned, went and ran 13.19 (full street trim, 3.25 pulley, I'm only a 2.9 away from solid twelves), and only pop the hood once a month to check fluids and change spark plugs every 15-20k miles or so. Low maintenance. Quote Link to comment Share on other sites More sharing options...
