sorry im not exactly good with all the technical stuff but the sheet that came with the cam reads as follows:
Comp cams
part #: 12-242-2
grind#: CS XE268H-10
intake exhaust
valve adjustment: hyd hyd
gross valve lift .477 .480
duration at
.006 tappet lift 268 280
valve timing open close
at .006 int 26 btdc 61 abdc
exh 72 bbdc 27 atdc
these specs are for cam installed at 106.0 intake center line
intake exhaust
duration at .50 224 230
lobe lift .3180 .3200
rocker arm ratio .00 .00
lobe separation 110.0





this is the first engine i have built and i was just told to line up the marks on the two gears for the cam so that is what i did
the engine is running at 190 degrees
the timing is set at 8 degrees btdc at idle
idle is at around 800rpm
im not sure what compression it is but i can find out unless there is a way to find out by telling parts: heads etc
the headers are close to the starter but it only affects it over long periods of time
the engine will start right away almost all the time but sometimes it will almost instantly die they you have to hold the peddle to the floor to start it and it takes a while
i havent checked the floats but i have tried two carbs and one was brand new
i am almost positive the valves are right
i cant find any vaccuum leaks
they are 1.94 heads

hope i gave enough info

thanks
