Speedmaster intake porting. Hopefully I can make something out of this

If a had one sitting hear I would gladly do it but at this stage I think it would be wasted time. Who in their right mind would pay or port a set of small block heads to the 280cfm area and throw an out of the box (especially dual plane) intake on it. I gotta get this intake finished, flow the exhaust side of the head, and move on to race stuff. I know Hughs did some flow testing with that intake but they may have flowed the intake by itself. I may make up an adapter to try this out of some lexan I have here just for curiosity.


If I had a dollar for every unported intake on ported heads I could pay off my house.

Anything more than a gasket match is all most customers want. Quote them 750 bucks to fix their intake and watch them lose their ****.

They say “it was 1500 bucks to port the heads and that’s with a valve job and surface and you want HALF that to port the intake?????? Sounds crooked to me...sounds like you want to make money on the intake you didn’t charge me for on the heads...there ain’t no way I’ll get 750 bucks worth of performance out of that... and many more things like that have been said to me for telling them I don’t port heads and not the intake.

My rough measurements say most single 4 intakes have a runner length 200% longer than the port in the head. That means you have all that extra surface area to shape and finish.

Guys just don’t get it.
