jetting

[notsed]

well my motor is almost back together and i want to make sure my jetting is close. my mods are, cool head with 21cc domes, fmf high rev pipes, boyson superstock reeds, timing is going to be at + 4, toomy 2 into 1 filter intake, stock everything else. i am at 600' above sea level and its around 70 degrees. I did a search but nobody has the same pipes, any suggestions would be great thx

21cc dome at 600 ft shouldnt bump your compression too much so whatever they run with t5's should be close

well i did some lookin around and found this:

 

Sea Level 1000' 2000' 3000' 4000' 5000'

18cc 197 178 171 170 165 145

19cc 183 167 160 158 152 137

20cc 169 156 149 146 140 129

21cc 156 145 138 134 128 121

stock 130 125 118 112 106 100

 

so 21cc would give me around 150? also is this safe with 4 degrees advanced if im running 94 octane?

yea that should be fine.
