Great video, and a great idea!

Thanks, I supply these head intake port lumps as a kit if needed. Tom

[@justforever96]

So adding all that material doesn't obstruct the flow of the port? Seems like you're always hearing about people REMOVING as much material as they can without going through the walls. Does the redirected flow just more than make up for the loss of total cfm airflow? Also seems like a narrower port would increase the airflow velocity and give better atomization and swirl in the chamber...does that have any effect?

[@Texassince1836]

Adding to the port floor and removing from the port roof redirects the air flow for much nicer entry to the cylinder.

[@VinnyMartello]

Volumetric consistency is what you need. This gives that intake port a nice even path. Without it, it’s kind of like an expansion chamber on a 2 stroke where the air spreads out. And thus it slows your airflow. Dyno results have proven these work by a dramatic degree.

Qual a necessidade de fazer esse tipo de serviço nesse cabeçote. Tem alguma melhora no rendimento do motor?

[@gualidchahoud7295]

Friend, I want to do this job But where I live There is no such piece of aluminum, my question is, if I just do the job of eliminating the intake towers, would it be okay? I live in Venezuela

I sell and ship these worldwide. www.12bolt.com/store

What if you don’t have a lump and you just remove the bolt boss. What will happen?

[@telowe2000]

The velocity in the port will go down, creating a lazy port.

[@dawg1157]

Hey Tom! Just curious....why wouldn't they work for a 235 head? Wrong size?

[@VinnyMartello]

235 Chevy has 4 intake ports and these absolutely won’t work.

[@boomboomrory]

What would you charge to do a lump port conversion on my 153 head ? Thanks, Rory

[@VinnyMartello]

I know this is an old comment, but you can do most of it yourself!

@monstersxr800 Olá, eu fabrico esses lump ports, aquí no Brasil. Se tiver interesse me contate. Eu já testei, e os ganos são sensíveis, principalmente com válvulas maiores. Um abraço , Francisco.
