***CHESTNUTXE*** · April 13, 2016

so many figures there for all,look at the blue thunder cleveland heads !

gerg · January 21, 2017

Some port mould analysis on clevo 2V, 4V, and Edelbrock heads. Very interesting. This site was paywalled a few years ago and I subscribed, now it's owned by another mob and runs on advertising So anyone can access it.

Thanks for posting gerg. Very informative. I've got a set of 2v closed chambers arriving from Cam tomorrow. I did some before testing as they had been touched by someone. They only went about 10cfm better than standard. Hoping for much larger gains after Cam's work as they are going on a meth skid car.

Thanks for posting gerg. Very informative. I've got a set of 2v closed chambers arriving from Cam tomorrow. I did some before testing as they had been touched by someone. They only went about 10cfm better than standard. Hoping for much larger gains after Cam's work as they are going on a meth skid car.

Hey Ando what was done to them to gain 10cfm? I plan on just tidying up the bowl and short turn and getting a 3-angle seat on mine. Also a 3-angle doesn't do much at max lift, but part lift improves heaps.

ando76 · January 22, 2017

Not that much really. Someone had got in there with the burr and removed some material but it was kinda all over the place. Cam had to re-do it all, fix x section, tidy up around the valve guides, throat area correction etc etc. it went on and on. I'm expecting decent flow out of them now. Will probably flow similar to my clevo units.

You can sorta see from those plugs how just a good seat cut (Cam's is pretty special, I.e. More than 3 cuts), bowl/throat correction and some love in the short turn really picks these old girls up. The good seat cut really works right thru the lift range. Yes it's most effective when the valve first cracks and up to mid lift. Here it accelerates the air and gets the air speed really happening. Of course that then carries thru to the mid to high lift areas.

So you can see how in reality it works the whole way thru the range. You won't get as higher airspeed and swirl in the mid to high, without first creating it in the low. It's a flow on effect if you like. It's also something that you may not necessarily see on the bench, in fact there may even be some slowing in the high lift 'on the bench'. Put them on the engine and they make more power than the cfm suggests and most times more than heads with big high lift cfm flow. Well that's my experience.

Send them up mate, you know you want to. Don't need to come to me, just Cam in Brissy.

gerg · January 22, 2017

Yeah that's the exact theory I'm applying on my revamp. Get the momentum going earlier and the kinetic energy will keep it flowing till the valve closes. That's something that a flow bench can never pick up: stop-start flow and pulse tuning.

Even though mine's only a 302, it could still benefit from a better shaped port. Aussie 2Vs have pretty shit flow for the size of the port, most flow charts I've looked up are at around the 180 mark (marginally better than a 351W) whereas US units are a consistent 200. Could come down to the quality of machining down into the bowl.

Sure I could send them away but I'd like to have a go at the ports myself and get the 3-angle and back-cut done outside.

ando76 · January 22, 2017

Good plan. I'll PM you.
