Here's what I'm gonna do...try.
I have a very clean LS6 intake to install. It is used so not sure what all I need to install it when I remove EGR/AIR setup. Help on this please.

I am thinking Patriot CNC LS6 heads/cam combo with rockers from Summit. I will order new pushrods. Will 7.400" be ok with stock gaskets? I want around 11:1 compression so 59cc chambers should be ok, right? I intend to replace oil pump while I am in there. Should I or is it a waste?

Camshaft specs are 226/226, .585 in./ .585 in., 112 lobe separation angle or,

232/230, .580 in./.578 in., 110 lobe separation angle.

Any comments on these cams? MS4 better? 5.3 heads better? Will I need injectors?

I have a DiabloSport II. Can I do any tuning after the install with it? I am many miles from a dyno/tuner but willing to haul it if need be.

Thanks in advance,
tatasta

i see several things wrong with your combo but insted of picking throught it just give Texas Speed a call and they will take care of your every need for your heads cam kit and a mail order tune , and that is all you really need to know

they will take great care of you and answer all you questions

Thanks for taking the time to read my ?s. I will take you up on your advice with TSP although I am really interested in the problems you people see. I can get help on what to buy but I really want to understand why they are poor or good choices. I have alot of wiexperience th sbc engines but Gen IIIs are all new to me.
Thanks,
tatasta

the main thing i see wrong is the 11:1 compression, you will have to mill the heads get shorter pushrods and maybe notch the pistons . and yes you should figure on a new oil pump
and if you are going to keep the stock pistons and not notch them you should consider a 243 casting

here is what i would recomend

the 5.3 is a better head but it will have clearence problems with certain cams

again i am no expert by far but these are just some of my expericences whil i was looking and choosing a set up

it depends on what you want all out power or like stock driveability , but i tell you texas speed answered all my questions and helped me pick the correct package and my car now runs 7.0s on motor alone and it is a full weight pig and it's deep in the 6s on the gas . but just call them and they will set you up

Definetly go with the 5.3 ported heads but dont have them milled, just have them resurfaced by taking a couple of thousands off for clean up. that cam you selected should be fine with that combo. You will then have 10.5:1 compression which is plenty. Look at my sig and the combo that I went with for some other hints. Its a great combination and the car is a beast and has great driveability.

PREDATOR-Z

Get True LS6 243 casting heads (64cc), run a .040 Cometic gasket and the 226/112 LSA cam
That will make a great 420rwhp combo. (+/-)

Thanks for all the information. I appreciate all of your help. A guy can go f ing crazy reading all these posts. Too much info in these forums for a newb to sort through.

Again thanks for the help!

The LS6 heads are a better cast, you can mill them down to desired cc if you want to. .040 gasket will allow for tight quench area.

You're not going to have a very cooperate DD w/ the MS4. Trust me. It's a really agressive cam. The 230/232 cams would be a lit nicer to drive daily. I'm getting a similar Turbo grind cam for my DD soon. (doing turbo next year, prepping).

W/ those cam #'s you can do a TSP V2 torquer, close to it and TSP has nice cams. Mind as well do the Oil pump and timing chain while you're in there. For the Ported pump, get a thicker O ring w/ it too. You don't want to take this thing appart more than you have to. -=Modified=- and I have learned a hard, but priceless lesson.

Get a PR length checker too if you plan on going w/ a thinner head gasket and/or milled heads. It's like $20 but woth it's weight in gold to solve PR length questions and to eliminate possible valve tick. Have fun w/ the Oil pump, it can be a PITA. Stuff some rags in the oil pan to keep the pick up tube bolt from falling into the oil pan.

When you remove3 or install the LS6 intake, BEWARE of that damn oil pressure sending unit on the back of the engine. It's between the intake and the power brake booster vaccum line. You'll have to turn the intake twords the drivers side to prevent snapping the unit off.

Oh, lastly... Be jentle removing and installing the cam. You don't want to nick the cam bearings. THey're only brass and bruise easily.

I'll keep my eye on this thread because I've got a LS6 intake, Z06 243 heads with Comp springs, 3200 stall and Im wanting to get the Patriot 226 cam myself....I'll probably dive into it all this summer.

Thule

i bougth that patriot H/C package, they dont make the bigger cam no more, so i went with the 226/226, i still think its to small, but i will just get the ms3 if i dont like it, i bougth a roller rocker cam from patriot as well,

Nothing wrong with 11:1 SCR on pump gas. DCR is far more important in this case. Also, the 59cc patriot heads have welded chambers, they are not milled. You definately will not need to flycut the pistons with a 226/226 cam.

Why would he notch the pistons for 59cc heads and then go with 243s? Welded chambers are a better way to go when bumping compression. You don't lose any PTV clearance.

sorry dont mean to threadjack but would the 5.3s work fine with a torquer v3? no clearance issues? what gaskets should be used stock mls?

BOWTIE

I was told they would and and was actually considering that option at one time (using a .040 cometic gasket as well), but ended up going with a custom cam with a few deg less intake duration and a nice bump up in DCR.

I can't stop looking at your avatar

Tatasta, try to get the most compression you can by using the thinnest head gasket you can get, before resulting to milling the heads. Shaving .015 off of the head gasket will increase your compression more than milling the heads .015 and will improve you quench as well, which just makes everything better (less detonation, less emissions, better flame travel, more power, etc.).

Thanks for the compliments. I actually saw some other guy on here with this avatar and i thought, "Dude, I gotta have that."
