Thanks guys,..
Dave is handling this all better than i
expected. The block is toast, it had been repaired
3 previous times, and is no longer worth the risk at hand.
Dave is looking to replace the block and get a crank
Dave needs a KB stage 10 raised cam std deck 4.375 bore
and a 4.375 crank shaft.
Those dam rev chips, you put in a chip and the actual rpm is activated
300 to 400 rpm sooner than what they say on the chip.
We had a 10,600 chip in the box , but Dave and I said that
incase the sprague rolls or what ever freewheels the motor we did
not want the motor to see that much. The nearest lower chip Dave had was a 9800, this motor see`s 9200-9300 so even with the extra couple
of hundred rpm le-way it should have been fine,... but
with all the unknown factors that goes with running new combo`s
you just have to set the motor tune up on safe, so anyways the motor could have had about 2.5 grams more on the clutch and still been able
to be on the safe side, ....on a side note.....looking at the computer we could have had 4.6 grams on the clutch and ripped a big one down the track.
we where light on the clutch and the motor just drove threw the clutch and it saw 9507 rpm at 4.3 seconds, the rev chip kicked in at 9500 even though it said 9800,...other than it drove threw the clutch the rest of the data collected was great, very nice,.....so get a new block and crank and Dave will be back out,...I hope
