Andy,
I have never understood what good is does to put the PCV that close to a breather. The PCV can not pull any crankcase vacuum because the airflow from the breather to the PCV has very little flow resistance. Does the filter for the breather also have a check valve that only allows outflow of air?

Rich- system does work in that it keeps oil in the motor instead of spewing out a valve cover. BTDT My intent wasn't to create a vacuum in the crankcase. I just copied what someone else did that worked for them. As Andy said, it could probably be improved upon.
68 Valiant- was auto-x now track day car

I don't know how effective that PCV arrangement is. That breather setup was the result of a bunch of frustration with other systems that leaked oil during sustained cornering. I'm sure the design could be improved even more if we wanted to spend time on it. If it was my design I'd probably focus on weight reduction as the next step.
Copper tubing reminds us that this is a home built car dones for function and purpose. Same for the front air dam some might recognize for it's other application.
But for a magazine article, painted all grey or something would probably work and look fine.

.... The new Charlie's oil pan fits nice and looks like it is going to work really well. Not sure if you can see much of it in the pictures posted so far but figured you might be interested in that detail.
Thanks for the pan pictures. That 73-76 K-member really screws thing up.

But all for function and purpose. It doesn't have some pro touring air bag system or narrow bling front tires or 10K interior upholstery job.

Andy, is there a build thread on the Valiant itself?
No thread but I am writing a book that will feature lots of stuff from the Valiant build.

Cool, thanks! I've always wanted to build a 66 Valiant similar to this.

Tim took the car for some shake down runs the other night. Says he can feel the additional 100 hp. I weighed the car after he brought it back and it is now 3130 lbs with a 55/45 split. Original weight was 3250 with a 56/44 split. So we took off about 100 lbs and most of it came off the nose. Still need to fix a few things before heading to the track on Monday.
Cool! Please keep us updated.
Sounds small but that's a SIGNIFICANT change!

Peak power for engine from the dyno sheets is at 5800 rpm. 5800 rpm in this car with the existing gear ratios and tire size is 150 mph. Guess we'll see what happens on Monday at the track. The back straight at PIR is long enough to carry full throttle for some time. Not sure if the car will go 150 though, that would be really hauling.
The car has plenty of power. I went for a ride today with the wide band setup in my lap. Tim punched it a few times and the car really gets up and goes. Very impressive for 2.94 rear end gears.

Good luck with the car on Monday. Hope you get some good track time and testing in. Looks like good weather.
Go get'm Tim!
