I read about this on another Z car related website:

NOS Energy Drink's IMPORT FACE-OFF at Dragway 42 in West Salem, Ohio (Cleveland area) will be on Sunday, June 29th.

The only problem is that I don't think your Z car would qualify.

ENGINE

Only OEM 4-cylinder motor entries allowed. Engine must be of automotive import origin or offered as OE in compact cars sold in North America. No air-cooled or rotary engines allowed. Motor swaps allowed as long as they stay within the same manufacturer.

But that's OK with me because my Datsun isn't an "Import!"

Oops, my bad, as they say.

I didn't see the rules for 'Quick four' and 'Bracket classes' which allow all the usual engines. The 4 cyl. only class was for front-wheel drive imports.
