It's been awhile ago and I'm just getting back around to trying to get this car running as it should. Does anyone know off hand what effect my 83 240 having a reportedly Canadian K-Jet head and cam would have on it? I'm told the cam, I forget if it's an A or B, should have slightly more power above 3K or so, which it does not, at all. The compression should be the same on them yes?
And yes the K-Jet injector holes are plugged. This was on the car when I got it.
On a related note, could it in any way account for pinging at light throttle cruise, 40mph-ish, with the timing verified correct? Only way I could ever get rid of it was to plug the vac advance and just manually advance the base timing a bit till it was drivable. Set to 12BTDC it's a dog, and pings, set to 9 or 10BTDC it's a dog and does not ping except for an occasionally single ping at WOT.
Which is making more noise than accelerating the car. I went through the clean throttle body, set idle, clean IAC, new 02, clean AMM, check for vac leaks, new gapped plugs etc, etc bit a year ago when I bought it. Still idles rough, still surges at idle till warmed up a bit, still down on power. It isn't obviously rich or lean, both fuel pumps are new, I believe the FPR is fine as well.
