Chamber size for iron head stroker
LOL ^^^^^ You haven't posted a picture of anything, EVER. J.Rob
I actually have posted some pictures. So you are wrong again. Nice to see you are using your other name today.
And yes, I found a better picture of what I'm talking about. I can email it to someone if they want to post it.
The thing is, you are actually AGREEING with me and you don't get it.
Even in N/A applications the chambers are moving away from all the quench and pulling the chamber away from the valves. If the chamber walls are vertical (or close to it) it's bad for flow, even if you use a 55 degree valve job.
Also, the picture I found shows how important it is to get the chamber away from the exhaust valve on the roof (if I'm thinking correctly...) so you are using as much of the valve diameter on blow down and reduce pumping losses on the exhaust stroke. You can use a smaller valve and port on the exhaust and make more power.
As I've said...quench is highly overrated. That doesn't mean run the piston a .100 down the hole either. It means closing the quench from .080 to .040 will net maybe, maybe a few HP. It won't reduce net timing a single degree.
Overrated.
