Why do you need a 10K tach, even the highest dollar motors only turn 8500 rpm....and thats to produce 850hp on alcohol ????? :gmc2:

The engine will be a LS2 with ported LS3 heads, four Weber IDA's on an Inglese manifold, solid lifter cam, shaft mount rocker, larger diameter pushrods, etc. It will redline around 8500 rpm so an 8K tach wouldn't be adequate. I'll also be taking the truck to open track practice days and with around 650 hp it won't have a problem making use of the 160 mph speedometer on bigger tracks... So in this case I do need a 10K tach. ;)

I had a guy build the 10k tach to fit in a stock cluster, still waiting on the speedo lens to be printed.
