Little Help with the build.

[Gus]

Hello I'm new to the forum but have been in the car game for a little while. I have some questions and hoping to get some answers that will result in the best power for my money. I'm working with a 2010 4.8 Silverado 4x4. I currently have a KNN cold air, Flowmaster drop in muffler on factory piping and a PCMforless tune which is already set up for Long tubes. My questions follow.

I would like to purchase a set of longtubes but need to have cats available due to local emissions check. Our area does not look for California standards but must pass a physical inspection. I have been thinking about the Ceramic Pacesetters and welding in a Magnaflow universal cat to the Pacesetter Y pipe. Any reviews of fitment in this type of setup? Trying to avoid the 1200 Kooks or other high dollar setups.

Next on the list I have been thinking a lot about a cam and wanted to get some recommendations for the above setup. The engine doesn't need to have rough idle since I use my truck to pull a boat and a car hauler I need my brakes. Most of the time sounding fast and being fast are 2 different things unless you got the $ to do it right. I am looking for a cam that will give lots of Mid range power where I'm going to use it. I am not looking for a cam that is at 5000+ RPM before it starts to really pull since I do not plan on changing the torque converter out.

Due to the power increase from above do you suggest swapping out the servos in the transmission or is this a unnecessary modification? My truck has the 4 speed and if this is something I should look into is there a specific part number I should be looking into?

Finally the tune currently in my truck was done via HP tuners and I do have access to one of these units now and prefer not to pay for the new cam tune so I wasn't sure if anyone could share a tune for the upgraded cam?

I know this was a bit long for a first post but I rather ask then waste money.

welcome. you def. wanna upgrade servos if not everything else in the trans, these trans are very weak once you start adding power, as for more advise there will be mor e peeps on here monday, theres a racing event this weekend so things are slow.

Cool thanks. I see tci makes a 1-2 servo and a 4th I think also? Should I pick up all of them?

A 212/218 cam would fit you nicely. They make hollow cats that can be used to pass visual inspections as well.

I was browsing some of the Posts and saw that cam and someone else mentioned the 212 216 also. I do apprciate the feed back. If my truck has the single bolt cam can I simple buy a 3 bolt sprocket to make the switch? Didnt know if there was a length difference. Cam availability and option are much better for the 3 bolt.

Yes thats what you need to change to a 3 bolt, i would jjust get the 1-2, just buy a corvette servo, theyre like 15 bucks at oregonperformancetransmissions.com. Idk how good you are with trans but buy the billet accumulator pistons also. May wanna look at up grading trans coolers since youre gonna be pulling, a good one is the true cool 40,000 gvw, also availible at oregon perf. Think its 118.00$.
