so got this car a few months ago previous owner didn't seem to know to much. was only boosting 5 pounds idle was kinda shitty and low downloaded the fsm adjusted the idle checked voltage on the tps sensor got it idling steady. Next I started trouble shooting the boost all line was already swapped to silicon so that was a plus everything was ran right I check for my boost pills one was missing so I got the appropriate size carb jet bam got the 10-8-10 split anyways on to what this is about curious if this sounds ported to your guys ears previous owner said the owner before him said he believes he had it ported but wasn't to sure didn't seem to know to much. So here is a video on YouTube of it

While heavy porting (bridge etc) do have a distinct sound, I'm not sure you can definitively tell on a street port. Especially if it was done well and there's a standalone ECU...which there should be on a ported engine.
I will tell you (confess) that your engine idles better than my UNported engine since I added a lightened flywheel. One day I have to make the time and effort to do my own adjusting.

If it idles just under 1k there's a high chance it is.

When I was adjusting the idle it seemed to like 900 to 950 anything under that and it starts to get a very distinctive loop to it. I'll be picking up a rotary compression tester sometime soon so depending how that comes out I might be finding out real soon if it is ported and if the ol girl needs to go under the knife. Thanks tho for the insight fellas.
