Ran 11.53 down the track ! now i hear aloud ticking!
i went to the track yesterday, ran 11.53 @120 mph. as soon as i drove around to pick my slip up , noticed my cars ticking pretty loud and hesitating, and when i give alil gas sometimes it sounds like its gotta slight backfire.
1st thing i thought was a bent pushrod, as soon as a got home i checked them out , there all straight! witch really didnt surprise me cause i just reaplaced them 6 months ago (with hardened pushrods) ..... what could it be, collapsed lifter ? bent valve ? any ideas ?
ifs it a bent valve, i think im gonna trash my GT40 P's and get new heads... How does the edel RPM performer 2.02 heads, perform against a pair of AFR 185's ?? please help ...
Thanks guys.
