i was at a race in bakersfield lastnight, and the eraly parts of this morning and i saw the tz in a dirt oval sprint car, i must say it was a really hard engine to start, i mean i have had engines that dont like to start but i was helping this guy get it running but man it was hard, i must say once it did start it was awesome especially in the dirt oval races, wow it was amazing the power it had, it was such a nice engine because it would spin the tires the whole way through the turns and that is what you need
