427 Ls7


Recommended Posts

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.

 

THANK YOU

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

Make 500hp? Beat his SRT8? As long as its stock...

 

This would be a good option to consider, a 408 can be built by many different shops, this is just one shop/option...

OR

 

A TVS1900 should do the trick from...

Any route you probably choose, you will basically need supporting mods like LT Headers, exhaust, trans work, torque converter, custom tune, etc.

 

A couple of others have reached the 12's with pretty much just nitrous and supporting mods. 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.
