It's really that expensive to have the lower intake manifold ported? I was considering doing it while I have mine out. Maybe I could find someone local that can do it for cheaper. Definitely not worth it for that price tag though.1320 Junkie did mine. He seems to only do a few a year, and over the winter time only. Can reach out on IG to him and see when he is accepting orders again.
Unless you are making 800+ HP, it is a waste. It’s worth maybe 15-20 HP. $800-$1000…. Just add 1 more psi of boost and call it a day.
Yea it’s that expensive. I paid $850 3 years ago and that was with a sale going on. You can try local for sure.It's really that expensive to have the lower intake manifold ported?

another bump for 1320junkie. he does amazing work and again, if your not making 800+... its not worth it. porting the lower is for max effort cobras. there have been back to back dyno graphs in the past showing no gain below 800.
I think there is still room for improvement on the lower manifolds of these cars. It would be fun to experiment if you had access to a dyno for a weekend.I wonder if adding some kind of divider in the center to guide the air would be worth anything? So the air isn't just hitting a flst wall.
Slawko Racing. They do the porting for a lot of race engine builders. And again, it's only really ideal for effort builds, definitely gains to be had over a 1000.
