95hp and early turbo heads (62-63) are closed chamber cylinder heads. Take a look at the preceeding photos in the thread. The closed chamber heads have a sqush area at the bottom. As it turns out the problem with pinging/spark knock/pre ignition has less to do with the compression ratio and more to do with the combustion chamber design.

Great job. It looks fantastic. I'll be over in the next couple of hours to pick it up.

I have gotten some PMs from members asking how the car is doing so I'm posting an update. I have about 2000 miles on the engine now since the re-rebuild and it's running great. The engine is quiet and consistent, no pinging, and great power. I drive the car to work when the weather is nice and on the weekends. I have the YH dialed in that it starts easily in all temperatures (if the bowl is full) and the turbo is loving the cooler air as we get into winter here. The Safeguard is doing a great job of protecting the engine under boost. Right now Ken Hand is building me an F/B flow turbo with the ceramic coated backing plate and exhaust housing I have had sitting on the shelf for a couple years now.

I had clearmask and ceramic paint and chrome coating done on the car to protect the paint and chrome, including the KH wire wheels using the OptiCoat Pro+ product. I have had this done on other cars with excellent results, it's like the worlds best wax job and it lasts 6-8 years.









Here's the front trim all removed so Clearmask could be installed behind everything:




This winter I'll be converting to an electric fuel pump and I'm going to try the Revolution Electronics fuel pump controller that will auto-fill the bowl when the key is turned on and uses RPM as the input. This can be hidden under the dash so no issues with looking not stock. I'll be doing a fuel pump center bypass plate (the one from Clarks) so the engine bay retains the stock look. Pump will be the 1-4 PSI Facet cube.

Here's a link to the Revolution electronics product: [www.revolutionelectronics.com]

I also bought a Roger Parent ball bearing accelerator linkage kit and his billet aluminum clutch and parking brake pulleys, so I'll be installing those.

Today I'm hard-wiring in two USB ports under the dash to power my phone, GPS, and Bose bluetooth speaker that I mounted under the dash using a GoPro camera clip so I can just clip it off to return to a stock look. Good stuff!!

Five 90s and a 180, that gas is gonna be confused by the time it gets to the carb. Great work, that is definitely a car that's better now than when it was new.

LOL...I was thinking the same thing. I actually had it plumbed three different ways before settling on this setup. I did test the flow and it's moving plenty of fuel! Got it all over myself in the process, all part of "the experience".

You do great work Nick!

Today I made some fuel lines and installed a fuel pressure regulator and fuel gauge to go with my new electric fuel pump. I was happy with how it came out. Maybe I didn't need one b/c the highest I could get it was 2.25psi, but good piece of mind. Set it at 2psi and the engine seems happy.

Nick, I only get between 2 and 3 with the electric pump only and the return line not blocked. It goes higher when the mech pump is in control. Pinch off the return line hose if you have one, see what happens.

Looks good Nick! Nice work as always.

My wife and I drove my car 6-1/2 hours each way to Crested Butte, CO for the Tri-State Corvair meet last weekend. The car drove beautifully both ways and the turbo was working hard on the mountain passes, easily keeping the car at speed and even gave some really nice passing power a few times. The car ran just fine at altitude, but at over 11,000 feet on Monarch pass it did need a little help to idle.

The cherry on top for the weekend was the car won first place in the early open category at the show. Good times and great people as usual at the very well organized Tri-State event...and beautiful weather too!

Look'n REAL sweet Nick. One thing I miss about Colo is cruising the mountains in my Turbo Vert, along with fly fishing and easy access to Rockies skiing. What I don't miss is the Army.

Did you or are you or are you planning on running up the Peak, great drive?
