Walbro 307 and 40# Red stripes ?

[GNXV6]

Hi all I've been out of the loop from Turbobuick.com for some years now and trying to get updated. I have a walbro 307 in my tank and 40# redstripes installed a long time ago. Is that enough fuel to support mid elevens or should I update to walbro 340 and 60lb injectors like I see many of you guys now have?

Thanks
George
