0-60 mph: 7.1 seconds. Reply #60 – March 11, 2007, 11:09:36 PM Quote from: ZondaC12;133387oh . is that why theyve been kinda hard to thread!? :flame: :wtf: :eek: :eek: :eek: i thought the threads in the heads were just dirty (although actually they thread fine until i start feeling a grinding so maybe it is dirt). are the threadings even different at all? im just always worried about messing up bolt threads, often irrepairable damage. if someone had told me, i woulda dun it! so...whats the difference anyway? ill go and get those today, but just curious. i like the way you expressed the answer too, "ding ding ding!!!" yay i won the h.o. conversion game show!!! prize? pair of gt40 heads:evilgrin: a man can dream....Darn I already have GT-40P heads:DI noticed that you hit 0-60 in 7.1 seconds. Pretty good for a car with a peg leg 3.08. I'm betting that when I get my HO swap done with the GT-40P heads and 3.73 Trac-Lok I should go 0-60 in ~6.5-6.8 seconds.Oh where do you do these *tests* :D ? If I tried to do that by me the cops would nail my ass. Quote Selected
