I've been following this thread with some interest, as I've contemplated similar modifications to my pre-crossflow 4/4.

I'd be very interested in hearing if anyone has actually tried installing a 3.7 gearset in a pre-crossflow car. This setup should yield 3428 RPM at 70 mph and 3094 RPM at 60. Will the stock 87 hp motor support this?

Thanks in advance for any replies,
Warren
