The adjustment instructions are in the Pontiac Chassis Service manual. 64,65,66, & 67 manuals all target ~1050 RPM [(1030 to 1080RPM) after the Throttle Return Check (dashpot) vacuum hose is...

John, I saw your post over on the HAMB. There are a couple carb gurus on this site that might be able to answer the question if you post it here.

I see that Ames reproduces the '65 4 barrel fuel line (N129A) in steel. It may require the inline fuel filter.

Many moons ago before it was reproduced, I made my own out of steel following the...

Your ‘65 326 has the large base Rochester 2-barrel.

The only engines that used the small base 2-barrel in 1965 would have been the Tri-Power 389 or 421 which used the small base center carb.

Your routing of the fuel line is a good recipe for percolating and vapor bubbles in fuel line.

Using an HEI is a game changer with these things. They tend to have a shorter mechanical advance curve and add a lot more vacuum advance

If I were setting up your HEI for the little 326 I would...

The 326 I run has about that much timing in it. 18 initial, ~38 mech, 10 vac. But my engine is a 0.040” over rebuild with #143 heads, so comp ratio is prolly in the mid to high 8s. I’d say it runs...

19 is way too high for your motor, yes. That depends a lot on the compression. For instance, the factory initial timing setting for my 1979 400 is 18 BTDC, and is the setting I use. My engine is...

19 degrees Initial timing is high for any of these engines if they have much compression in them. Total timing a bit high, but I've had a few over the years that were fine in that area.

Myself, I would put a piston stop in to verify my true TDC. Your timing mark may be off. No Pontiac I’ve ever owned would want that much initial timing.
On the other hand, I believe in giving the...

I’d say pull the plugs and see what they show . If it looks like it’s fat still it’s not likely detonating . That pinging can be hard to hear that’s for sure, a really rich mixture is harder to...

You need to be more detailed.

Do you have 39 to 40 degrees in just mechanical advance, or is this amount seen with your distributors vacuum advance plugged in?

If you want that cushiony, almost floaty ride, I'd opt for the stock type spiral shocks. They'll do just that.

I've had the Gabriel shocks on my 1969 Firebird and they are fairly supple as well.

Common as dirt.

The main reason folks put a "Ford Solenoid" on the fender, is because they don't have sufficient voltage at the starter solenoid end of the "purple wire".

On the all the occasion’s when the motor does not crank is it up to normal running temp, or will the issue take place with it cold also?
