Guess my age! I mean mileage!!
Here’s the motor currently, dialing it in seems like it wanted more mechanical timing and less initial. It currently has a 600cfm carb. Since I do have that 2800 stall converter ported heads and long tubes might try a 670 vacuum secondary or 750. Or maybe a 650 double pumper lol.
The last picture is a make shift bracket I made for the passenger motor mount to fit the 5.9 using the stock 1967 273 motor mounts.
