Initial timing is at 18 BTDC and 34 Total. I capped off the Vaccum advance for now until I figure out what I’m doing. Idle in park is around 950 and gear is 700. It really doesn’t want to idle lower than that.
That's a 250 rpm drop going into gear, and is pointing to;
A) That 296* cam,which, IIRC, is a P4120661; 252/252/[email protected]/ @28/32 lash, .557/.557 [email protected] arms. That's big enough to kill the idle-rpm power quite significantly if the Static Compression was not raised in compensation, and/or
B) a factory low-stall TC, and/or
C) and a throttle that is too far closed.
The engine just doesn't have the torque at low-rpm that it needs. This is why the compression test is so important. If you only have 120 psi, there is no cure for what ails this combo until you get the pressure up. But by 150 psi, you can look to other areas for a cure. But if your pressure is over 165psi, you are in big trouble.
