Chevy 193 Swirl port Mission Impossible

[Carnut1]

They are 2.1" valves that flow 318 at high lift and a 1.94" that flows 260

A lot easier to get a -$treetRa¢e- if you show up with ID-able "swirl port" truck heads on vs CNC SRH V Factor heads on your racer.
Is the 1.94" version with a 50° valve job angle?

[Carnut1]

Yes

Incredable good thread and with videos.
Thanks thanks Charlie for your efforts.
You've allowed us to learn with you.
You are one of the guys that make this forum worth while.

I am very busy so I don't give Speedtalk the time I used to. Thanks

Medication. Seeing what happens now if the fin/ vane/ ramp is at the 8 o'clock position would be interesting to me..
Great videos.

I do quite a few videos on changing ramp clock positions and recording air and dykem flow patterns. 8:00clock happens. Thanks

When are we going to see how they run on an engine?

[Carnut1]

Not for a while. Thanks

[F-BIRD'88]

I will go back thru your videos and review them.
Thanks Charlie.

Gotta say I enjoyed your videos on these... I'm guessin' these won't be ideal at that port volume for something like TPI unless it was a mite bit over 350ci

At 240cc and over 300 cfm they will need some compression and cubes! Thanks

I enjoyed all of it! My son and I built a swirl port special a few years back that runs way harder than it should. Some mild port and chamber work, 1.6 exhaust valves, hyd roller cam, 9.3 compression, headers, rpm intake, 4180 hoĺley. Now after seeing Charlie's testing I've got some ideas to make it better.
