Recommend me a converter for this 273 - 727 combo

Thanks for your valuable info! Now I know what to look for and where.

"Ifitsgotwheels", since you also have the 273, may I ask how much difference did the higher stall converter make for you?

I've got a relatively wild cam (551 lift). The convertor let's the motor flash to 3000 as if it I was slipping a clutch. I think it's well worth the money. Just remember a big convertor adds heat to the trans so you'd better get a good trans cooler
