Thread: LS4 Build, what to buy?

Great looking car, I need to get that hood for mine. Unfortunately I don't have access to a lift to drop the cradle. I still need to get an engine hoist. But It's almost ready to come out. I just gotta finish pulling everything of the front of the engine, and then pull the headers and down pipe. After that it's just a matter of separating the engine from the trans.

I also scraped the supercharger idea. I totally forgot the intake on the ls4 is backwards.

A couple jacks and jack stands will do just fine.. a crane helps too

I did mine all messed up.. so don't take my advice (also the wire harness is a total *****) but I lifted my car up almost 2' and hooked the motor to a crane.. dropped it slowly while attached to the cradle.. got it down and lowered the rear of the car to lift the front and rolled it out the front...

The engine is ready to come out. There's not much I can do till I get a hoist. It was a lot more work than anticipated, but it was tolerable.

I think the wire harness was the worst part. It took me forever to figure it out.

I agree bro.. every time I thought I had it figured out another damn ground would appear haha

Somebody left me a gift. Now the fun begins.

I had to drill new holes for the supports because they weren't long enough, but it's together and ready to use.

Without a lift I didnt feel like dropping the cradle. It seemed easier to just keep all the work in the engine bay. As far as leaving the engine in, I don't think it's possible to do all the work I need done with the engine in the car. I should mention I have very little experience in pulling/ building engines, so this is all new to me.

This is the thread i used as a starting point for my build.

Finally Got the engine out. Now the real fun begins.

I got a parts list together. Ill be spending just over $5500 for everything, that includes a new trans from triple edge performance. I'm also getting the cam, pushrods, and rockers from lunati instead of comp.

custom cam?

I think im going with one of the ones they offer. part #21460701. Im hoping the idle will be what im looking for.

• Advertised Duration (Int/Exh): 267/278
• Duration @ .050 (Int/Exh): 217/228
• Gross Valve Lift (Int/Exh): .549"/.566"
• LSA/ICL: 112/108
• Valve Lash (Int/Exh): Hyd/Hyd
• RPM Range: 1800-6400

Its been a while since I posted. I put this project off to deal with other projects, but parts are finally coming in. I ended up going with a cam package and dod delete kit from Texas Speed. The cam package I bought was their High Lift 212/218 .600/.600 112LSA. Updates and Pictures coming soon. Does anybody know a good source for getting a custom tune made?
