did it make a difference on your setup? I already have the throttle body being port and polished by Tim. Just waiting to get it back. $150 sounds like a great price for new era to do the porting job, and if i get 5-10 horsepower out of it, I will be super happy.

I am interested in this as well. Any numbers or results would be appreciated.

I have no idea. I did it when I did a h/c swap. So there was no way to tell. But I know that 20 minutes with a die grinder was definitely better than knowing that we should've and didn't.

Not to be rude, but if you ONLY spend 20 minutes on it, you probably didn't do too much. I'd like to consider my self a "head porter" that has decent ability with a porting tool, and I can say that in 20 minutes I wouldn't have much done if I were working on ANY manifold be it plastic, aluminum, or a GM iron intake.

If you spent only 15 minutes in each individual runner with a carbide burr and then finished it with a cartridge roll, that's two hours right there.

It was figurative. I'd say honestly it was about um, 57 minutes. LOL!
Seriously, all you do is make a template of the head's intake port. Then transfer to the intake so you know where to match it up. Then use the carbide burr to blend the runner to the proper port opening. It's not like it scuffs or anything if done right. Pretty simple stuff. But as I said, it's just port matching. Not porting. So I'm sure it's not worth much gains.

Now I understand a little better N4cer. I was kind of scratching my head esp coming from YOU!

There is a big difference between a "gasket match" and a ported intake as you pointed out. Many people don't fully understand this. I couldn't begin to describe some of the "ported" LT1 intakes I've seen that are simply a very VERY crummy gasket match that looks like it was attempted with a 32" chainsaw bar. They'll spend time trying to get a 1/2 of a percent gain when there's a 10-15 rwhp gain from porting further into the LT1 intake manifold by working the roof of the runners until they break through, welding, smoothing, etc. ...

As for grinding on a LS6 intake inside the runners (not a 'port match' as N4cer was pointing out), this is something I'm going to attack myself in the upcoming weeks after I get a few other side projects out of the way.

I ported my LS1 intake and gained oh, about 000

Sorry for the brief hijack.

Interesting information there. What was the throttle body used? And would the gains be even greater if the FAST intake was ported? Thanks in advance for the info.
