ls6 stage 2 heads.
ls6 stage 2 heads. not much information on these exact heads.i have a few questions regarding these. Anyone running them, if so, what cam?
whats the biggest custom cam specs i can do with a 113 or 114 lsa without having to flycut the pistons?
tsp told me the tsunomi is will fit (235/240 .654 .609) but my custom 236/240 .612 .609 or even the 236/238 .602 .605 wouldnt fit dont really remember why they said it wouldnt fit, they told me to try and get me to buy the tsunomi or torquer 3...both huge in lift. most their cams have one thing i want but not the other or vice versa.
main question, which custom cam spec will complement the heads best while keeping semi streetable( alot of people saying they love their ms3 as a dd).....seems a little sluggesh on take off, so something a tade smaller is what i`d consider perfectly streetable.
current set up. custom headers, intake, 2.5 x pipe exhaust.
future mods, be adding some kind of IM(fast) and TB and pully. maybe nos
haha

i'de say the tsp torquer 2 or 233/239 cam. you don't want the biggest cam possible, even if it fits you wont be able to use its potential because the heads and more importantly the intake most likely want be able to flow enough to match the lift and duration of the cam. even with something like a FAST 92.
thanks for the advice, the 223/239 was a consideration. the reason for wanting a slightly bigger cam is cause i want a better peak power and high rpm range. thats why i was thinking instead of the 236/240, ill do the 236/238? its a little bigger and smaller on the intake and exhaust ports. would this fit without fly cutting
ps, i was just trying to know what was the biggest i COULD go so i knew, Not that i was going to do so. just need to know the limit without flycutting thanks

Unless you give much more info on the heads, no one can tell you what will or will not fit.
Are they milled?, valve size?.
If you do not have this info, your best bet is to put the cam you want in; measure PTV clearance and then decide on flycutting or not.

why do u want more peak hp? you do realize that you are only at peak for a split second and that peak hp and tq has a very minute effect on anything. (cept dick measuring) as i said before matching everything together will be your best bet, for ANY application. what's the point of having big hp/tq #'s if you can't do **** with it cuz you only make big numbers for a split second?
well its in my 240sx, so i weight about 2850-2900 without me in it. and i want something in the mid to peak power yes. i want something that gets good power at about 2.5k and really screams at 4k. once you shift after 1st gear, your always in the 4-7k range anyway, so why no get a cam thats best in that power band range?
but anyways, yes that is what i am asking, what would be the best cam for the heads, on the mild/semi big side.
(brian, i agree with you on what you saying, i just rather want at least a 234 236, then a baby 224/224 cam, i dont want to loose power after 5.5k-6.)
BTW you car sounds like a best in a half, specailly for that small cam, 112lsa?

^^ exactly, thank you,
from the specs i`ve given, example: 236/238 .602 .605 114lsa, would the stage 2, 5.3 heads be a better choice?
i`ve looked up alot of dyno sheets and people are only making roughly 410-420whp with ls6 heads and v2, with all bolt ons, im hoping to have around 430whp, but w/o the ported TB and fast IM. when all is said and done, with pulley,IM,TB i`m hoping on roughly a good 480rwhp....

^ how is this so hard? stage two 5.3 heads and full bolt ons with a 238/242 made 511whp, and many other set ups close470-490whp.
but anyways, back to what was asked above please.... thank you

the cam and push rods are the last part to choose .the cam ties in all your pieces,stall,gears,heads ,intake ,etc...PREDATOR-Z knows his stuff.trust his recommendation.head flow numbers help in determines cam choice.

found a thread, called 318 to 470whp.. its the ls6 stage 2.5 with a ms3 and no fly cutting from what it looks like. all i can say is wow!! supporting mods of course.

give pred-z or pat g a pm with all your specs. i dont know about pred but pat g has a form to fill out to get all your specs, send it in to them and they'll spec a cam custom to your setup. this is what pat g specced out for me. said if i went manual it'd get about 450rwhp and 420-430 with the auto.
Cam recommendation: 1986 Monte Carlo with LQ4 6.0L short block, 64cc PRC stage 2.5 LS6 heads, .041” gasket, Victor Jr. intake with carb, Auto with 3200 stall, 3.73 gear, 1 3/4” long tube headers, 6600 rpm shift points, 7000 rev limiter.
230/238 .600”/.604” 111LSA +4 advance

^ will do,
but am i just not getting something, on many peoples combos ive looked up, when they are running a ms3 cam, it can fit with the 5.3 heads(w/o flycutting)and not the ls6 stage 2.5 heads, but they have the same specs, 2.02" 1.575.... besides flow numbers, the ls6 has better flow number... only reason im being so...****.. is cause for me, being in college and only working part time, even a minor $2000 is a big purchuse for me to spend. just want to make sure im satisfied the first time.
