Best Torque Converter mild Commando 273

With a small cubic inch engine and healthy cam like yours I'd go for as much stall as possible to make up for the shortage of torque of your small engine. 2500 would be the minimum I'd run. But in the end it's what you really plan on doing with the car. I'm a gearhead so I always go loose on the stall. If you don't plan on running it real hard a 2500 is plenty loose. If it were me I'd probably look into something in the 3200-3500 range. Also, if you buy a good quality efficient converter you don't need to worry about the stall speed being less than your hwy cruise rpm. Most converters made 25 yrs. ago weren't technologically advanced enough to be really efficient like what we have today. For that reason back then you always wanted the stall less than cruise rpm. I recently ran a 3500 stall in my Cuda with 3.23 gears and 28" tires that cruised at 2600 rpm. Had no slippage problems whatsoever even with a very torquey 408.
