I couldn't wait I looked it up myself ported and polished LS2 heads, nice. Love that Intake but wished it flowed a little better, but best on the market right now, except a single plane converted into fuel injection. Was the fast intake ported any further than stock.

Default LPE vs. Stock

I must admit the badge is sweet.

Here is a comparison between Stock and the LPE 403

Not a mild cam. It is in the middle of the LPE Offering. It has some chop at idle but the power delivery is smooth.

CAM specs 234/240 598/608 114

I don't think it would be cheaper, not with the prices that I am seeing.
The real difference is that his stroker is making about 60 rwhp and 60 more on the torque than the Z.

I drove a new Z-06 the other day. Nice car. But after driving a 402 stroker, I was not impressed with the Z the way it comes from the factory. It needs mods. Headers, a cam and tuning.

my 2 cents

Why no headers, or did I miss them in the list? Just curious as to why that wouldn't be part of a packaged mod like this.
