Highest N/A 4.6 Power

The important keyword is "fully" ported heads. Almost all so called Stage 2 even Stage 3 cylinder heads are not fully ported. This can leave 20-30 RWHP on the table. I'm not talking about a full race port (contouring the valve stem boss, polished guides, etc.), I am just talking about a fully hand ported head. To properly and fully port a head it must be CNC'ed first then finished by hand. Of course it also depends on the cam selction. Bigger is not always better in some cases. You have to take the head flow and port velocity data and choose the appropriate custom grind to compliment the cylinder head's characteristics.

I will be doing heads/cams fairly soon and I am very interested to see what she'll do. I think there are a bunch more out there over 350 than people realize. There were more than I realized.

Well if there are more that I'm not aware of, they sure are humble and are hiding in the dark.

If I made over 350, I'd sure as hell post it up EVERYWHERE.

yeah but they are bound to have a friend or car club buddy or even a mechanic that does post in the forums and they would definately mention the 2V NA cars making over 350rwhp since we all know how hard it is to reach. Its a small world when the internet is involved and word travels fast.

350 rwhp on a 2v 4.6L is very rare to post on these boards.
