What Are You Doing To/With Your Car Today?
Holy compression test batman! Started the tuneup late this evening, so I only got half way done. I'll get the points and timing tomorrow (or next weekend). I was tempted to just drop in my new (used) Unilite dizzy, but I'll just save it for the 360 build.
The little guy and I went to O'Reilly's for some gunk engine cleaner and brake cleaner, found some hot wheels while we were there. Yeah, it's a '55 Chevy, but it's cool so I had to get it. Note the masking tape with numbers on the plug wires, saves a lot of aggravation.
I have been having an INTERMITTENT loss of power, over 4,000 or so. Sometimes it'll keep pulling, and other times it just does NOT want to, and this is at 5:30am with nice cool 50* air temps. I am not too concerned because of the 360 that I'm building. Even if I destroy this 318 I won't sweat it.
Edit:
I was thinking that the intermittent issue of no power over 4,000 rpm may be a fuel delivery issue.
With the new RN14YC plugs, the idle came down to a nice and smooth easy 650 rpm. Air temp was around 85*. I am about 2 miles away from the Santa Rosa Airport (STS) elevation of 128'. 0.035" gap, 30 ft-lbs torque on the plugs per the service manual.
Since I was replacing the plugs, I figured I'd slap the compression gauge on it and see what I had. Not so good. Been running our awesome California unleaded gas with untouched 675 heads. Any bets on whether it's the rings, or exhaust valves?
Close ups of the plugs... They are about 3 years old. Note the insulators on plugs 1, 4, 5, 7, 8. Now, per the service manual, figure 4 page 8-61, it looks like I've had overheating issues, which I can confirm, as I had to replace the Griffin radiator, which sprung a leak where the cores were not well welded on the top right side. Also, you can hear detonation when hammering the throttle when going up steep grades, at elevations less than 1000'. I may end up retarding the timing when I replace the points and set the timing.
