Best ever trip with my newly 16 licensed daughter. Had her driving through the Ozark twisties. Brake in the straight, if you are a little hot going in, she will hold, power out in the last third…. Best week ever!

Had to change out the overdrive solenoid due to failure this summer. About 7500 miles since the tranny install. Still pleased with the swap.
40-75 is consistent. 1:1 drive to the 3:55 axle. 0-60 would require consistent shifts on a truck 4-speed. NP. Not the smoothest shifting transmission but it is tough.
First change in place. Finished headers to 2-1/2 dual pipes. Single muffler with 3 inch single out.
Did a 40-75 punch with original exhaust, 30 second average on two runs.
Same trial, after exhaust upgrade, same conditions, 20 seconds.
I will let this run over the weekend and review thoughts on Monday.
Reminder: Engine upgrades only, fuel delivery will remain carbureted.
Exhaust, cam, heads, intake, carb, block are allowed in your response.
The chart is one that I made up. Pretty good at excel so built the formulas and started playing with possibilities. Rpm changes with change of gear, tire sizes. Helped me find my happy points.
On my last post, it says “positive” rear gears. Should be “posi” or limited slip.

Gents,
I feel bad that I did not close out this story.
Finished the install in 2019. Added 3.91 position gears last year. Awesome cruiser now and good mileage. Ran 1800 miles on a drag and drive adventure with great success.
2500 rpm at 75 is nice and acceleration is such a change from 2.91...
Best thing that happened at a local car event.
Drove my 67 LeMans to work that day. Pulling out, noticed that I needed gas. Headed for the station but got flagged down by couple of guys. As I pulled to about 50 feet they were yelling and pointing right. Glanced to the right, two more...
I have polyurethane (front and rear) in both of my cars. One is a cruiser and the other is a dedicated road course car. I installed all of them myself and lubricated properly during installation. Neither have any issue with squeak.
As far as torsion bars, the cruiser has stock and the road...
I have a 72 so the same bumper. My advice from experience:
Get a friend to help you in the final install of the main bumper.
Get some pool noodles to protect your paint.
Loosely install the main and the outer brackets (pinched but not tight) to front of the car, (you can reach the bumper nuts...
Agree that your current PV may be good. Next, go to the primary jets. Your A/F meter is a great tool to get the final tune in. Based on your video, I would drop 2 sizes from your current.
I am assuming that you have a Holley carb. Somewhere around 750 cfm. Likely not a double pumper.
Clarification from post #13.

What you experienced is an air pocket in your heads, hottest point in a running motor. When the thermostat opened, the steam in the air pocket took the path of least resistance and blew out the radiator fill.
To avoid, pull off the top heater hose at...
