ok guys i just bought a 4k off ke ping it real, now its had mild headwork to it, I'm going to pull off head and calculate the current compression ratio, what i want to know is what other peoples compression on their 4k is and what they would recconmend i have.
the 4k has elec dizzy, extractors, 2 1/4 inch exhaust, reground cam (unknown), and yeah,
i was thinking 10.5:1, what would i have to change so that it wouldnt f@$k up at that high or higher? medicine man said i could go upto 12:1 but i would have to get it tuned so that it wouldnt blow up, could i do the tuning myself or would i need a dyno?
cheers travis. i want power!!
