HEI distributor with vacuum advance. I can pull the vacuum advance off and the idle goes up, even after I plug the port on the carb, the idle stays up until I plug the line back in. Not sure what is actually doing to the timing as I don't have a working timing light at home. I do at work, but I don't think it would make it on the highway.
As far as I know, its a stock motor. Guy who originally installed this motor in the blazer said it was a "crate motor". Thats about all I know. The engine ran great when it was in the Blazer. All I did was separated the carb, installed some offroad seats and needles, adjusted the float bowls, blocked off the fuel slosh thing at the back of the bowls where the 2 bowls meet.
4.10 gears in the diffs, 3.83 first gear in the R150F Toyota transmission. 36" swampers.
Not towing anything. Yes this is in my 88 4Runner.
I plan on putting a proper exhaust on it when I get the money.
No clue on how the carb is set up as far as metering rods and stuff. Thats why I need help. Its an Edelbrock 1406 600CFM with electric choke. Electric choke is hooked up and functioning.
