Hello, I have a few questions about putting a 6.0 in my mustang. I have a line on a really low mileage 6.0 with the 317 heads. I dont know much about these yet. I planned on having the heads CNC ported with a front mount distributer, carb intake etc.. I'm just wondering what kind of power levels can be with a head/cam 6.0 with a stock bottom end. This is a budget build so I dont plan on doing a stroker. Just a street cruiser, low buck... Any thought would be great.

I had plans on a turbo setup but changed my mind.

I have a set of 317 heads on my 402ci ported n polished W/stainless valves n stiffer springs. These heads with a fast 90mm intake made 482rwhp without much tuning.

As for the hp of the 6.0 (377ci), prolly 420ish rwhp? Depends..

Automatic or manual ? What cam you thinking of ?

There was a fellow ls1 member down in southern Kansas that stuffed one in an older olds cutlass with a carb and an automatic. He made some nice numbers and didn't spend a ton a cash.

My .02...

Good luck

I have no idea on the cam. probably a custom piece to match the heads. Just trying to get an idea on the power numbers can expect. It will be an auto, most likely a th400.

I stuffed a 231/237 115LSA in my 402. It lopes somewhat but pulls like a beach !

I tried a 228/232 114LSA in a stock ls1 and it loped about the same, or maybe a lil worse. That was a 5.7 so for a 6.0, might be just right.

Depends on if you want top end power or usable low end street torque.

i too am putting a lq4 in my mustang and was wondering the same thing. mine will have the z06 valve springs, 317 heads, stock ls2 gto intake, and z06 springs. i will also be installing a gt42 single. while its over kill for the stock bottom end I want to keep my options open when i do decide to forge the botomend. btw this is a full on time attack road race car.

The 6.0 will make some impressive power in stock form with just a cam and springs. I would cut the heads on an lq4 to bump the comp. a bit. And it doesnt take alot of cam i had a 212/224 in mine...

Well, since you are changing the intake, and for budget reasons, I would look no further than the L92 heads. You can grab a set of those for DIRT cheap, and they will outflow your 317 heads all day long. GMPP carb intake again, for cheap, 22x/23x @ .050 .6xx/.6xx, 112-114 LSA, MSD 6010 (you don't need no stinking dist) and go make 550-575 HP.


Edit:Oh yeah, did I forget to tell you I have a 6.0 going in my Mustang as well? See sig!

With that much cam do you have to do anything to the pistons??

Also with a LQ4 and LQ9 how much distance is there in ptv clearance?

I am building an LQ4 for my truck also. I have done alot of research on this swap. You guys running the stock LQ4 pistons need to seriously think about swapping the 317 heads out for 243's to get the compression up on NA motors. Or, you can swap the LQ4 pistons out for some flat tops, but you will still be in the low 10 to 1 range with the 317 heads. If you want to get up close to 11 to 1 compression, then you need some flat top pistons and the 243 heads to get into the 11 to 1 range. If you build a motor with the LQ4 stock compression of 9.4 to 1, you will leave alot of power on the table unless you guys are going with some kind of forced induction. My motor will be running LQ9 pistons and rods. This will give me the stronger rods, the flat top pistons and PP stage 3, 64cc heads that will put my engine right around 11 to 1. My motor is going to be naturally aspirated too.

1)ALWAYS check PTV anytime you do a cam/head swap.
That being said, you should be fine, but I am NOT PROMISING anything either.

2)Are you asking what is the difference between teh LQ4 and LQ9?

Dollar for Dollar there is no reason not to do L92 heads. You won't be sorry.

i was goin to do a seperate post on this but thought it might fit in.

im lookin at a lq4 out of a 03 yukon. i have 62 cc (milled) prc stage 2 243's
and an m6 out of my 00 t/a...i read that some blocks have the crank set up wrong ..something to do with length?...i believe this was in the 99-00 models though

also this should stil have the same relucter wheel right..?...

and where would this put my compression with the 62 cc heads?

also how is that intake compared to the ls6..or do i have to change it for it to match the ls6 ports?

The more I look into this, the l92/6.0 combo seems to be the ticket!

only down side u can see to the l92 heads is the huge intake valve will cause ptv issues alot earlier

I had a stock bottom end LQ9 in my gto with stock 243 heads (spring upgrade), tr236 cam, stock gto intake (LS6 style) with 42lb inj, and longtube headers - put down 445whp.

To the LSX Mustang group....what are you using for headers? Does someone make a custom set or what?

Gen414

iTrader: (38)

You can do 1 of 3 things:

1)have a custom set made

2)Buy a set of 351W Fox Body headers, whack the flange off and weld on a LSx exhaust flange

3)Buy a pre made set. Anthony Jones Engineering (AJE) is one company that makes a set, and I am sure there are others.

I already had set of Fox Body headers, so I am going option 2. Now, I have heard you CAN get into some fitment issues going this route. But, since I made this set a few years back and NEVER used them (1 7/8 - 2" stepped), I have alot of time wrapped up into it. And, I can always re arrange some tubes if need be. That being said, I would STILL probaly go option 2 even if I did not have the headers. You can pick up most Fox Body headers CHEAP!! I bought a set of BRAND NEW 3/8" thick exhaust flanges from a board member with shipping for $53.

I didn't know AJE made a set. I guess I'm going to have to look at their stuff.

I looked at the AJE web site and could not find any headers. Does anyone have a link?

Their site is kind of screwy. I do not have a link, but I do know they make em
