Or call the converter manufacturer, give them the info they need , they'll tell you what you need...
But also agree with all above...you need your full cam specs...along with alot more info on the truck..

I used to run a vega convertor ( approx 2200 stall) behind a flat top 350 with 500/300 cam...worked good with 5.13 gears and t350
