Hey guys, i am thinking about h/c for my 00' M6 ws6 with 57k miles. it has a lid, bellow, Free mods, Ported MAF, Stock internal motor with tune, full exhaust- pacesetters, ORY, 3" pipe all the way (no cats), 3" QTP cutout, hooker areochamber muffler, Luk gold clutch w/ aluminum flywheel, Full suspension (excluding k-member and upper/lower control arms), Strange 12 bolt with 4:10's and alot of other small crap im forgetting. What do you guys think about this List??? BTW, it is a non daily driver street car that will rarely if ever see the track. Thanks for any imput!


*Updated list*

* Precision Race Components 5.3L Stage 2.5 Cylinder Heads Fully CNC Ported & Assembled With Stainless Steel 2.04" Intake Valves, 1.575" Exhaust Valves, & PRC Dual Valve Spring Kit with Titanium Retainers,
* GM Head/Cam gasket set,
* ARP head bolts,
* ARP Cam retainer bolts,
* TSP Hardened Pushrods - donno what length,
* LS2 timing chain,
* TSP ported oil pump,
* Comp cams "R" Lifters,
* ASP underdrive pulley/belts,
* Cartec ported Ls6 intake, <- already have
* LS6 coolant crossover, <- already have
* BBK 80mm throttle body, <-already have




Now for the cam choice....

1: TSP XS Series Camshaft: 233/239, .595"/.603" 112 LSA,

2: TSP Magicstick 4 - 239/242, .649"/.609" 112 lsa

3: TSP Magicstick 3 - 237/242 .603/.609" 112 lsa

4: Futral Motorsports FM13 - 230"/232", .595"/.585" 112 lsa

5: VHP accelerated lift cam "XXX"- 222 / 228, .551 / .551, 57* overlap, 115 lsa (i already have a set of the crane 1.8 accelerated lift rocker arms i was going to use for a 383 stroker i cant afford anymore. Dont worry, i didnt plan to use these with any standard profile cam.)



I'd like to see anywhere over 400rwtq. Anyone have some imput/opinions/sugestions for any of the parts or cams??? Thanks!

if its not a daily driver and I would say that the F13 and 222/228 is something that I think you would enjoy but you could go bigger... its really your preference, 1-3 options are all pretty close and the magic stick is a very proven cam. You might want to look at GMHTP's issue of January shows the numbers of PRC stage 1 heads with the MS4. And what intake are you going with ? Ls6 or FAST?

EDIT: nevermind just saw the LS6

your choice of camshafts kinda range from mild -> mean
if your going to be running some nice heads might as well throw in a MS4 in there..

Wont he have to flycut?

bad95killer

With that specific Heads & gasket set definitely he will need flycutting

i would get a set of ls6 heads. my friend picked up power with slightly ported ls6 heads over the 5.3 heads

get the GM MLS gaskets- cometic .040 gaskets really arent going to do you all that much good/better. If you go w/ the MLS gaskets you may have a better chance w/ a cam like the MS4 w/o having to flycut if i am not mistaken.

aslo that VHP(?) cam has 57° overlap??? valve overlap you mean? if so... Where the hell did you hear/read that? lol

Actually, PRC's stage 2.5 5.3 liter head flows better than the CNC ported ls6 head they offer at a similar price. The 5.3 liter heads are getting high flow number throughout the lift range and see 310+ CFM at .6" lift. His head choice is one of the best values i've seen on heads lately.

Also, I just read on TSP's website that the ms4 is designed to be applicable without flycutting, however, with a big camshaft and thin head gaskets it may need to be done. I'd call TSP and talk to them about it. They are very knowledgable and can answer all your questions.

i think those 2.04 valves on those heads are going to eat up alot of PtoV clearnace weither he uses .040 gaskets or not.

i think any of those cams 1-4 would be fun to drive with that setup, i don't know much about VHP to comment on that cam.

I would worry more about the 1.8 rockers with most of those cams. That may be a limiting factor.

I wouldn't spend money on the BBK 80mm throttle body. Stick with a ported OEM unit, or upgrade to 90mm if you ever switch to a 90mm intake.

After speaking with Patrick Guerra, I'm sticking with the 2.02 intake valve. PtV clearance and port speed being the issues.

Go with the MS4 or a G5X4 and don't use the cometics as they can be a pain and aren't necessary. Also think about a different throttle body.

i've already got the ported ls6 intake, pulley, coolant x-over, and bbk t/b. i didnt plan on using the crane 1.8 rockers unless i went with a VHP accelerated lift cam, which seems very tempting. I would really like to stay away from fly cutting the pistons tho. Mainly because i planned on doing all this myself to keep my car out of the shop and save myself some money. ive done a couple cam swaps on friends cars so it shouldnt be to big a problem to do all this myself. i have most of the tools and can probably borrow the few i dont have. I like the MS4 after reading the GMHTP article, but the whole flycutting issue makes me want to stay away from it. I really want to use the 5.3L heads just becuse of the flow #'s and to raise the compression. and if the ms4 required flycutting to work with these heads, i'd rather chose a differnt cam. I wasnt set on any specific gasket thickness yet but the .040 would bring the scr up to 11.1 or so right? What ever i decide to use i will be sure and call TSP to get all of the technical detais straightened out. So i guess it just comes down to what cam would work the best with these heads? The TSP 233/239 cam seems like a good cam, ive heard alot of people running it. Thanks for the feedback everyone!


Edit: i think i'll go with the 2.02"/1.57 Valves, to be safe

i dont know much about it but they have some pretty cool cam technology. the way the lobes are designed the cam gets its lift with the Crane rockers. its different but very effective. saw it here: VinciHighPerformance

You can flycut your pistons yourself. There has been a few threads on it and it isn't to bad to do. Do a search and see if it is something you feel comfortable with then make a decision on a cam.

they may flow as good but look what size valve they are using to flow that. i have seen 2.055 and bigger on the 5.3 heads to get their numbers. the ls6 use stock size valves and flow just as good with less valve

westxwitesnake05

iTrader: (17)

hmmm good point. what is the largest valve you can go with on stock bore/pistons without valve shrouding or PtV clearance issues?

slammedchevy

iTrader: (13)

I really not shure about that.

Also get the comp oem lifters or LS7 lifters, I got a set of the crane lifters and sent them back, they just looked crappy compared to oem.
