Actually with that straight, you need some kick ass top end too. The C6BB7T with a 2045 pipe and 92mm header is your best bet hands down. THough all those engines are amazing.... But the C6BB engine is probably the fastest unmodded (acceleration and top end) engine out there.
The straight is 200feet right? I know that one of the guys from Elite hobbies in Covina runs a ninja .28 with a 16tooth clutch bell to get the top speed he wants. That is considered a big track now since the change.
