hey guys well im goimg turbo in my 4 door nnbs this week i.should have the 5.3 back in there this weekend but before i do that i want to throw a boost cam in there what cam.yall recomend me guys? mods on truck are gonna be 5.3 built 4l80 also need help on what size converter to buy its gonna be running on 411 gears im planning.on running a 76mm turbo might consider meth but still undecided ..plz help me out guys

 

I say you contact stock48 about cam choices. He seems to be THE guy lately with those isky cams.

 

If you want someone to spec a cam out your gonna need to give a lot more info as well. But like stated above, start with Stock48 as he has a pretty damn good idea on what does and doesnt work to get these heavy pigs moving.

 

well dont reay want a spect cam rather get something with proven number..also if it help truck will.be a street truck dont see much track times maybe every month or.so lol

 

His cams are proven. I love his 212-212 561-561 112 also know as the isky tripple 12. All you need to do is ask and he can get you one ordered quick like

 

thanks pm sent stock48

 

what cam are these turbo 5.3 guys running? also.should i rering the 5.3 or leave it as is?

 

Im running a speed inc TU1 cam and I love it. The specs are 225/225 .581/.581 113 lsa. But since your truck is a good bit heavier I would suggest the TU0 cam, the specs are 216/216 .561/.561 114 lsa. Should perform really well midrange and up top yet not bee too big so your bottom end should be pretty strong too. If the 5.3 is in good working condition I would just put ARP studs, LS9 gaskets, LS7 lifters, LS2 chain, pushrods and a good set of dual springs in it. May want to put 3.73s in it too to load the turbo a little more, but I would imagine the 4.10s would work too. I would also call Chris @ Circle D and ask him about which converter but I would suggest a 2800-3000

 

^^ thanks man that cam sounds good imma choose between the TU0 or isky tripple 12 ill eventually lower the gear to a 373..as far as arp studs and ls9 gaskets what are those good for? hold more boost?

 

Yea they are proven to hold significantly more than the stock gaskets and tty bolts. The stock gaskets and bolts are usually good to 15-17 psi but sometimes dont old that long. LS9 gaskets and either ARP studs or bolts can hold much more.
