3 more words to drive the head porters nuts.

[pittsburghracer]

Lots of guys have thanked me especially those porting on intake manifolds when I said and have repeated “think radius”. Since it seems like most of the head porters post in the small block area I’m going to post up 3 more words that jumped out at me years ago and I still keep in mind. These words probably won’t help those guys that grab a grinder 3-4 times a year but for the guys that really enjoy porting one of these days this will jump out and slap you and you will say that’s what PBR was talking about. I’m not going to get into what it means as until you see with your own eyes what I’m talking about it will make zero sense. This occurres when you are doing shortside work or let’s say usually 1/2-3/4 inch from the valve seat. If you have seen or practice this speak up. Those 3 words are “push the port”.

I get it, a guy that ported heads for over 30 years used those words a lot when trying to explain to the customers. I would stand there while the customer was running his head, rolling my eyes.

I wish my ol' lady would push the port a little more often.

Thanks PBR. This post reminded me that I need to push the intake into a box and ship it out to you already! lol

Don’t break your neck. This racing, and yard work, and shop work takes a lot longer in the summer.

I did pick up .1 from a PBR intake, victor jr. Possibly more once I drop some jet sizes.

I Like to hear that. At your ET it doesn’t come easily.

Three words I learned from watching and driving Dad's heavy wagon. "Low lift Flow".

That’s why I push so hard for that .300 lift number.

Dad spent a very long career playing with his flowbench and heads and intake and exhaust system until he got very high numbers at low lifts. And it paid off with a highly responsive engine that flys from idle to 5800 and revs like a small Chevrolet with an aluminum flywheel. And it idles amazingly smooth and has very high vacuum numbers with a pretty good sized hydraulic flat tappet camshaft. He used to get in lots of squabbles with the big port cylinder head guys that just could never reason why low lift flow matters so much. And, he used to listen to lots of folks telling him they could not figure out why their cars were a second slower with more and bigger/badder parts that flowed much more air at .550" lift.
