On my last shortblock with 10.5:1 compression I ran around 27 degrees of timing. I had my new shortblock installed in June and it was tuned at 26 degrees. I then started having problems with it pinging once it came up to full temp. I figured the heat of the summer was the problem and bought a fluidyne radiator but still had the problems. I then had my car retuned at 23-24 timing. Still no luck!
Once the car comes up to full temp, it will detonate. I also have a tune at 20 degrees of timing and it detones just the same. At 23-24 with a 12.8 air/fuel my car made decent power, 325+ with the moderate timing.
I have spent quite a bit of cash and have no idea what could be causing this. Is there anything I could check to solve this? I'm getting more and more aggrevated with the problem.
