That's just an absolutely horrible waste of money. A few pounds of boost with the stock or a mild blower cam along with bolt ons will blow that out of the water. Both in power, fuel eco, and drivability. Probably cheaper in the long run too. An extremely high lift cam is also a valve train wrecker. If you gave me all of those parts, I'd sell them for whatever I could get and do what I mentioned in the second sentence of this post.

I'm confident that combo will make the power they say it will. Not a doubt in my mind. I just wouldn't want to put up with the valve train maintenance, the crappy manners, and crappy fuel eco. And you've still got a small pile of additional money to spend on the exhaust system and valve springs.

From the ad … “If you are wondering if this setup is too extreme for your build, it is”.

A pro charger with a mild cam and upgraded springs.....would be faster, more reliable...for nearly the same price .

I’m sure but what are we looking for here?
if you want a car that is so radical that it’s a burden to drive around that’s fine I was there myself few years ago lol but if you want a reliable driver that can still run a number I think FI is way to go.

I have that combo in mine. It rips. I know of at least 3 other cars with it as well so no, you wouldn’t be “first”. Two of the cars are manual. Me and another are auto. It’s an aggressive cam profile. I’m using a circle D 4c with 3.73 gears and it drives fine. When you are down on the loud pedal and shifting at 8k, yeah, it’s a game changer. All this to be said, I’ve been the FI route with a ls3 vette. Same money and made more hp. Problem was heat. Ecs fmic set up just didn’t make me happy. I’m also learned what sustained IATs do. Meth was answer kind of. Anyway, I did head studs when I did mine and I have a full nitrous outlet plate kit to go on it with stand alone fuel on deck very soon.
to give a real world racing comparison, it’s faster or as fast than a lot of heads cam z06 cars as is. Tuned on 93. I think taking compression up and c85 would be pretty stout. A 416 under it would be FI numbers. A centri blower on these heads would be wicked.

That cam will have very bad manners if you are concerned about driveability, it has nasty overlap. Some have a very high tolerance of bad manners, if you like that it will deliver. 4* of overlap will give you very civilized street manners with a much fatter power curve, that cam is 21*.

With the smaller LS2 motor a set of 4:10's is the best bang for buck with a more usable 6th gear. That would be my first & number 1 mod, then turn the motor up if needed.

There are more friendly engine modifications than the one you have posted here, unless you like that.
