[quote=ztarum]I've got a Superformance on order. Engine will be a 351w from Performance Engineering with approx. 460 hp. Right now the car is slated to get a TKO 500 tansmission. Any thoughts on the merits of upgrading to the TKO 600 road race? The rear end ratio is 3.46. I'm most concerned with first gear, and fifth gear. With the 500, the first to second shift point will be at 44 mph. With the 600, it would be at 50 mph. For cruising at 70 mph, the 500 will be at 1980 rpm and the 600 would be at 2380 rpm.[quote]

ZTARUM;

Your engine will not like any performance demands below 2-grand on the tach. Having said that, forget about "cruise rpm" for highway driving -- the .82 fifth is the ticket in these cars.

With regard to the TKO 500/600 issue, the 600 is just a beefier transmission, designed to handle more torque without turning into a 5-speed hand grenade. Spend the extra few dollars to buy some piece of mind -- go with the 600.

By the way, you'll like the engine Eric and his crew builds for you. Our powerplant came from PE, too. Man does it ever roast some rubber!
