Need help with the choice of converter 727

Hi my english is not the best so hope you understand me.
I have a dart sport 360 stroked to 408 with j heads.
My power band looks something like first image

and with edelbrocks heads that i will use later on second image.
I have looked at this http://www.ebay.com/itm/TSI-10-Torq...0hp-/161735211124?hash=item25a82b7874&vxp=mtr
Before i stroked the engine i used a tci steetfighter 142200 3000stall and it worked good but it 's broken now.
I live in sweden so ebay is the best place to buy from other places the shipping almost allways cost more then converter
