For anyone running or looking to run the LS1 motor, be aware that if you have 853 heads you may be limited to only using the graphite head gaskets. The picture below shows the difference between early 853's and late 853's. The key area of difference is the inset pad that was only on the early heads and was used to assist in getting the heads off of the block.

This prying pocket reduced the gasket area around one of the cyclinders and the MLS gaskets would not seal properly. The OEM graphite gaskets aren't bad, but if you are ever looking to upgrade and you have the pad, you will be limited to using only the graphite gasket. In the picture below, you can see the early version on top has a pad under the third cylinder and the bottom later version does not.

Guys, does the SIKKY swap/harness kit works with the LS7 engine?

My mechanic has a LS7 laying around

midz350 the sikky kit only works with LS1/2/6 motors right now. I would contact them to see what needs to be modified to make the LS7 fit. They may be able to help on wiring harness, but from what I heard they aren't that good yet with the harnesses. Quamen, SnyperZ, and bbs350 would certainly be able to help you through getting it wired up properly. There was a thread on here with an LS7 350z. It was a race car though. I will dig up the thread.

Loving it! Just finished re-wiring the headlights, windows and wipers today. Now onto the tail lights this week and then all the relays to finish everything off. The block should be getting sent to the machine shop in two weeks and then I start assembling the stroker.

I just got finished reading this whole thread and I'm even more ready to do a swap. In my area, LS motors are the norm so having help with this swap would be very easy. A good friend of mine here eats, sleeps and breathes LS motors so he will be helping out the most.

Has anyone tried doing an LS swap with a vq35hr? Any differences with the SIKKY kit for an 07 Z?

Yup Yup I can't wait.. I have a question for you though.. are you running one relay for the tail lights and headlights or separate for each? Also what about your windows, are you going to run a relay for rolling the windows down and up?

I was thinking about just ditching the windows and maybe doing some Lexan windows..

I run one relay per window. The up and down function are simply done by changing which terminals get power and ground on the window motor. I just used a double poll double throw toggle for each window.

I am not entirely sure about the relays for the headlights yet. I have to see how many amps they are first. I'm guessing two though and one for the tail lights. I'm running only two blinker relays (left & right).

Royal T-

I forgot that I'm wiring my headlights different than stock. I am not using relays because I want my headlights to turn on automatically when the car is running like most cars. I have a switched power 20 position fuse panel on my car and I'm just going to run them to that.

Thanks for the info.. I will do the same for the windows too.. Also I like the idea on the lights turning on when the car is running.. So you are just going to route the lights to the fuse panel? Would like more info on this.

Thanks
