i want to build my 08 5.3 up but i need some opinions from those who have been there and know what will be good.

CAM: i want as much cam as i can use w/o sacrificing good drivability. i here people go back and forth about whats good for this or that my question is why go with a symetrical cam like the tsp 224R vs one has dif. duration/lift like say 222/226 .581/.586 or vice versa.... either way im wanting something on a 112 lsa.

HEADS: the gen IV 5.3's already come with 243's so i think i'll stick with them and have em ported and polished and possibly milled(please give opinions on why i should or shouldnt mill them)

STALL: i'm thinking something like a 3000-3200 rpm stall since my truck is my DD. i've been told to stay away from tci so what do the guys on here recommend

N2O: i think i would like something like 100 shot and i want the safest setup i can go with. im thinking about a plate kit but im open to sugestions. i know i need a safety switch, heater, and window switch.

TRANNY: what should i do to beef up the tranny and remember the key word DD!.

HEADERS: simple... dynatechs or kooks(yes they're makin em)

ok guys lets hear it

 

doesn't nitrous like reverse split cams? like a 226/222?

either way, sounds like you have a good set up planned there.

 

Split duration cams and how much split is a function of cylinder head flow ......if the intake to exhaust ratio flow is close then a single pattern cam is pbly the best but if the ratio is like 60% then a good 10* degree split is close if 75% then something like 5-8split ........so if you truly going to get headwork done then pick your cam AFTER they are flowed ........symetrical / asymetrical is the lobe design totaly different from single / dual pattern ......always pick your cam after you select your heads and compression ...... and yes big shot of Nitrous changes the thinking

 

i am running a 220/220 .581/.581 112 LSA on a 3000 stall and i love it. great power on bottom and top

 

very nice setup!!!

 

thanks! im just ready to get it to the track now

 

ehhhh check my sig, my DD, and NOS ready if i want it. but supposedly this cam is to big, yea i think not truck drives fine during regular driving and idles like a freak.

 

and if i stayed with the stock 243(z06) heads, would a symetrical or asymetrical cam be better? and if asymetrical how much of a split

 

For the tranny I'd probably look into a built 4l80e. My buddy just put a built 4l60e behind his 5.3 with 360 hp and he is already having trouble. These trannys are junk. But with yours being so new I would just put a shift kit and stall on it. You'll probably get a lot of life out of it since its only a year old. The cam in my sig is a little on the small side. It starts pullin at 4,000 but peaks at 6,100. I probably should have gone bigger. But the 112 lsa really sounds nasty. I got my pacesetter lts (non-coated) online for 287, ory was an extra $130 ish. Keep an eye on craigslist also, you can really save a buck. My eaton posi had 1,000 miles on it and I got it for $200.

 

Your confused on the aysmetrical / sysmetrical thats lobe design and for what your doing leave that up to the cam company as they dont post that info under normal circ

Single pattern /dual pattern or split is the thing to look for when you select a cam .based on your head... now just get advice based on that head I,m no expert on these heads but have to think they have a decent flow ratio so probably a spread in the 5-6* is lots but again the guys who do these motors will / should have that experience and for street vehicle with power brakes etetc 112 LSA sounds about right Now if that head has extremely good exhaust flow and it might then a single pattern cam is the one to use ......this is all a generality ...but many pick a cam and then heads and compression and thats *** backwards a well selected cam with your stock head and compression will be fine ......if you really want to get a cam that is selected by someone who does this for aliving call Chris@ Staub Technologies or google for his reputation etcetc for a cam tell him what you have and what you want to do he will spec a cam for you and sell you one ...yes the cost will be a little more than a discount store off the shelf cam but if you serious thats the way to go IMO .you have a nice new truck .do it right the first time ..if you want his contact info let me know but should not be hard to find on the net
