I have a stock LY6 that I'm wanting to do a cam, LS 3 intake, and header in my Nova. Looking for 450 ish rwhp with a T56 tranny. It looks like I'm going to have to replace the entire front drive and accessories to a 2010 camaro or vette. This will be used a just a street rod so I'd like a nice hot cam and the engine needs to look clean. That's why I'm using the ls3 intake and car accessories.

I know there was some success with the tsp vvt cams but not sure how good the tuning is? Can I reach the same hp with a non vvt cam without the headaches or is it worth me keeping the vvt and why?

I am keeping mine. You should be able to make 450rwhp with no problem using a T56 transmission. The people over at Texas Speed and Performance should be able to help you out. By the way I am hoping to be making at least that much horsepower through an A6.

Just a street rod? Keep your VVT. If your building an all out race engine, then drop the VVT. You most certainly can have similar power numbers either way. What the VVT does is "move" the powerband around for a broader feel. It doesn't make any more, or less power. I am keeping my VVT, and in fact just got my cam kit from Mast.

I'm only worried about two things with vvt. One being tuning on the vvt cam? 2nd is the front drive components such as water pump, timing cover, and all accessories I want to run ( alt, and ac). I know the cam phaser makes this stuff stick out about 2" further than a non vvt.

What come with the kit u bought? Cost?

Vvt is crap, ditch it. u can still run truck accessories with a car intake all u need to do is cut off the idle pulley on the side of the alternator and run a smaller belt, look into porting the heads and a 235 244 cam and 450 rwhp is there

My cam kit, Mast Motorsports # 964-203, is cam and springs only. With long tubes, and an ls3 intake, it'll make 505 at the crank. Plenty of power for me. I'm looking more for torque, than HP. $799.99 plus shipping.

Can u elaborate on why I should ditch? Also ur saying all I need to do is cut the pulley? I read where someone cut it and relocated it further to the drivers side. Do u have pics?

Powe

Does a tune come with that?

I did it on my s10, and vvt is more for fuel economy not for performance. If u have dod ditch that crap too.

Powe

Not sure if the ly6 truck engines have dod... I don't care about fuel but I just want a cool cruiser. Why didn't u like it? Elaborate please

No sir. I'll be using vengeance for the tune. It's pricey. Everything Mast sells is pricey. But that's ok with me. I budgeted the cam price in, long before the build began.

What tuning are you using?

Vengeance is a shop and they do their tuning in house using efi live. They recommended using one of their cams without vvt on my ly6. I had great results with the stage 2. You might want to ask them about their KAOTIK if you are shooting for 450rwhp, but that might be a little too much for the ly6s lower compression.

Do not use the VVT.

It severely limits the power potential of the motor due to the lobes that have to be used to keep it functional.

Do yourself a favor and get rid of it.

Corrected that statement for ya in bold.

VVT does not limit you because of lobes...you can actually use pretty well any lobe that you'd use on an LS3 setup with VVT combos. You are limited if you keep AFM/DOD however, on stock lifters, because they will not live with higher lift.

Powe

So does anybody know there's a limiting factor with use of VvT and T 56 transmission

That is true, my brain lumped them together today in one group. I was putting together a parts list for a DOD/AFM delete right before I typed that and it came right out my brain onto the keyboard. One of those woops moments.

It does limit the amount of duration that you can run and the cam timing that could be used.

The LY6 is a non AFM motor.


All you need to do to clear the car intake is trim the alt bracket and move the idle pulley. The Gen IV water pump will clear a Gen IV DBW tb as it exits at a 45* angle.

The 2010 camaro waterpump will clear the VVT as its the same one used on the L99 with VVT.


If its not an all out drag car. I would keep the VVT and get an aftermarket VVT cam.

There are pitfalls to be aware of when using a VVT system, for example different phasers, limiters and cam cores. Valve clearance is not easy to measure because you need to actuate the cam to full advance and retard. If you go with one of TSP or Mast's shelf grinds, you have a better chance of clearing your stock LY6 pistons, but you always should check. Converting back to an LS2 or LS3 timing set will give you more cam options.

I think futureuser has had the best results I've seen from an LY6 on the forums and he used a nonVVT cam, but in the year 2050 when my Nova is on the road, I'm going to annihilate him with my VVT-2 from Texas Speed (assuming he didn't modify that C6 accelerator pedal with a limiter before he sent it)
