What's needed for a full AFM delete

[gmckenzie]

So, I've got a 2015 GMC Sierra that I use to pull a trailer, with the NHT setup.

Very low mileage. Have not hit 45,000 KMS yet. But it broke on me last year and dropped an AFM lifter. Under warranty, but still cost me ~$1,500 as I was on holidays at the time and had to have it towed home, plus renting a 1 ton to get my trailer (underwhelmed by the GM 6.6L gas BTW). So I'm thinking I either sell it and buy a Ford with the Godzilla (don't want the headaches of diesel) or keep it and make it more bulletproof. Given the state of getting a new vehicle right now, and how unlikely it is I upgrade my trailer any time soon (RV market is similar to truck market, except the QA has gone to ******), I'm thinking it's time to dump the AFM properly.

 

So, what do I need to dump the AFM and build a reliable trailer rig? Options all the way up to a Procharger if it is useful. Bigger issue is finding a shop capable of doing it. I'm in Central BC, Canada.

 

I get that I'm talking cam and lifters, but what cam? And does the stock tranny (6spd) need anything? Truck has the bigger 3.73 gears, so I doubt I would upgrade those.

 

Any advice? Anyone done something similar?

 

Thanks for any input.

This is the minimum needed. Plenty of other vendors that offer kits as well; or you can piece together your own. Imo if your doing the delete you may as well go for a cam too. I would look into BTR, "Brian Tooley Racing".

Unless your doing this yourself, be prepared for roughly the same cost as a blower/install. 10k + cdn.

Money, time, parts, and a good mechanic if you cannot do it yourself.

******. Was hoping for about 1/2 that.

I came up with roughly $700 in parts if using a stock NON DoD camshaft. Then it would be the rest in labor to do the job. Obviously add like ~$200-300 for random gaskets, seals and fluids to complete the job.

Yeah labor isn't 1:1 when comparing USA to Canada; we get screwed over... I don't remember the actual hr's quoted but I do remember it's quite a bit more then the labor for a blower install (at least this shop).

 

They said that they have to pull the engine; that its just as hard if not easier than removing the rad and everything in front. I don't quite understand that, but then again they do a lot of corvettes. Probably have gotten good at pulling them.

Yeah, if it was half that I would be going with a cam too. Depending on the shop you may be able to get it for a couple grand cheaper then a blower install. But then you start thinking about cost per horse power and a blower starts making more sense. But imo a cam would be funner. 

 

There's a lot of labor involved. When I had my lifter's/vlom replaced I think gm paid out around 6-6500 cdn parts included? and that's without replacing the camshaft. I think a good speed shop charge's around 150cdn per hr.
