Badshifter - If you want to make your 1969 Z28 Camaro a street car again, at least you won't have to pull the engine and put in a DZ motor!

The CRG posting of a 1969 Camaro invoice of $3715.16 with the 427 engine listed at an additional $489.75 was quite a bargain.

Only another $12.65 for 10-10 Tuxedo Black paint.

I believe you need to reset your brake proportioning valve and can follow the procedure below:

As for having an issue with brake pedal effort, I would check your brake vacuum hose and the check valve which goes into the brake booster.

A 1979 Trans Am sold recently on BAT for $265K:

The car was reported to have only been driven 44 miles.  The Trans Am did have air conditioning, which would be great for those living in Florida where it get hot!

According to this vendor, the adapter needed depends on the manufacturer of the HEI ignition system you are using on your 1968 Camaro:

Nothing wrong with your shifting, Badshifter!

Looks like you were running the Z28 at Buttonwillow.  Haven't been to that track, but have visited Willow Springs.  Great fun!

Scott,
Took the 1979 Trans Am with the Checker Motors sub-frame for its bi-annual emissions test.  Passed as usual, but no fun for the technician as the distributor is located at the rear of the engine and you have to be careful removing the vacuum line when checking the advance as the motor gets quite hot back there! - Mark

My 1970 BOSS 302 has a similar 4 blade fixed fan, original shroud & spacer, with the original radiator (rebuilt), and it does not overheat, even when I took the car to the Fabulous Fords Car Show on a day where the temperature hit the 90s.  The Mustang also has Hooker Super Competition headers, which generate more heat under the hood than the stock exhaust manifolds.  As the car is also equipped with a factory oil cooler, it does help keep the engine cooler as Ford found out that during hot temperature testing, BOSS 302s with 4.30 gears recorded oil temperatures over 300 degrees without an oil cooler.

I still believe you need to check your ignition timing.  I checked the advance on my 1979 Trans Am before I went in for emission testing and the advance had moved from the factory specification of 18 degrees at idle to 10 degrees, which would have failed the test.

I would recommend that you check the timing as your 350 engine shouldn't ping.  I believe that the standard thermostat was a 195 degree unit and I wouldn't go lower than a 180 degree thermostat.  215 degree operating temperature is still within the acceptable limits.  What spark plugs are you using as the wrong plugs can cause your engine to run hot.

According to CRG, a 1 inch fan spacer was used for the small block V-8 in 1969 with the fixed 4 blade fan, whether the vehicle had a 2 or 3 core radiator:

As there was only one fan shroud for the small block V-8 in 1969, your set-up looks okay to me. 

Besides checking your ignition timing as previously mentioned, your thermostat could possibly not be functioning properly and not restricting the coolant flow enough for the radiator to cool the fluid.
