BPlumcrazy you gotta keep us posted bud!! I can't wait.

Oh I will, Shawn was suppose to take all the measurements yesterday for the heads and see what we can get away with. I'm in Africa for work so it's killing me not being able to go and check on things

I wont buy anyone's cnc head until I see the first pair of ports HAND PORTED AND FLOWED. Only then will I approve them to duplicate them with a CNC mill on the rest of the ports.

Or how do you know you dont have the same crap every other fool has?
As a sidenote, 20 hp from a cnc port is a droopy pink waste of money.


I can make 20 hp with granatelli coils and wires for crying out loud.

A good ported ls3 head from a cylinder head expert will make double that, or even more on a hotter combo.

I agree to a certain extent. The port is already huge, by the book its too large in stock form, increasing its size and removing material everywhere, so that the CNC cutter touches everywhere for cosmetic purposes is commonplace amongst all the CNC shops. Dont blame them, thats what sells, but thats also part of what is giving mediocre results at best in my opinion.

Its extremely unpopular to say this these days, but to see bigger gains than what we are seeing out of most of these offerings. Its going to take a smaller, more efficient head, that will likely have a smaller valve and flow numbers that may not be what you want to see. A LS3 head on a stock cubed LS3, needs less work with a grinder, and more with epoxy. Just my opinion.

Texas Speeds aftermarket casting and Masts are a step in that direction, and they are producing more power for that reason. My plan is to head even more so in that direction.

Most CNC ports on the ls3 are in the same ballpark. SDPC is just like the others.
