As I’m testing the engine to find out why the power is “off” I’m checking engine vacuum. I found this diagnostic chart for a stock car.
After doing this basic check at idle and at 3000, 4000, and 4500 RPM, I’m steady… So the next thing I’m going to check will be the fuel line pressure.
These are the results from a Chassis Dyno at Pick-Ups Plus.
The numbers are not what I was expecting, but the engine was probably ran very hard and needs a little TLC. I’m thinking that will start sooner than I thought.
One thing I’m noticing, the runs look good (though a little low) until it hits around 4100RPM, then it flattens out but it looks like there’s more to go. Going to investigate…
I was thinking about a solid lifter cam. I found this video, listen to the tap, tap..
I’ve noticed that some parts I might find for a 4-door sedan are actually listed as “Concours”. A Chevy Concours, or Chevelle 4-Door Wagon has much of the same parts for the 4-door including hard to find rear seat covers… More to come…
