None better in my book, call ATI and speak to Charlie Plott.
Been running ATI converters since '95 and I've run as quick as 1.28 60 foot off the footbrake in this 3880 lb. ride with a cast iron oval port headed 468 under the hood topped with a 4150 carb, backed by a turbo400 and 4.10 gear.
and 1.17 60 foot off the footbrake in this 3124 lb. ride with a oval port headed 522 under the hood topped with a 4150 carb, backed by a turbo400 and 4.57 gear.
I challenge any converter manufacturer to build me a converter that can match no mind eclipse my performance using an ATI converter!!
Some have tried and failed!
