I'm just wondering if I have all my fact's straight.

I want to put an iron ls2 together, this includes:

1. LQ4/LQ9
2. LS6 Cam
3. 243/799 Heads
4. LS6 Springs?
5. LS? Oil Pump?

Missing anything, or completely wrong?

I realize I'm , sorry in advance.

 

basically all a iron LS2 is just a LQ9 with 243 heads

 

Would the LS6 cam and springs be beneficial though?

Also, I'm a bit iffy on fuel quality here, would the lq4 be the better idea here to keep the compression down a tad?

But it wouldn't really be a true iron LS2 if it didn't have the 11.0:1 compression would it?

 

What is this going in? What are you goals with it? What is the highest octane fuel where you live?

 

It's going in an RCSB

Goals are 350 horse.. Maybe a bit more. Would be hitting it with 150 shot.

Potentially swapping it into my ECSB on occasion.

Just want a strong, durable engine.

I'm pretty set on this combo, just looking for a parts list really.

 

So you are asking for opinions and asking if your list looks right but then following it up by saying you are set on this combo.. So... Why ask if you already made up your mind. A LS2 has a alum block period, if you plan to do a LQ9 with 243's then you have a LQ9.

 

93 by the way, but lots of ethanol.

 

I didn't ask for opinions?

 

I built a LQ9 with 243 heads for someone with a 4x4 crew cab. In the cooler months its ok, but in the summer the heat soak and KR are obnoxious even with 93 octane, going to be switching out the heads to lower the CR.

Since your planning on putting this in a RCSB you may be ok.

 

Umm ??? You are looking for input right? There are many people that could give you info on what would benefit your setup. What I am getting at is I see numerous things you could do that may work better but if you are set on what you want then go for it. What this is going in and your goals are going to change people's responses.
