Stroker- want more ponies

I can't do power adders with the fast efi. I was curious about a roller cam so here is some more info. 3:55 gears, 3000 stall, 27" tires, runs low 12"s .
As far as a wideban tune, I don't know what to say to that, I guess I would need to know what is considered a good tune ?

12.5-13.5 depending on where it makes it's power at. I'm assuming you've set your timing curve up to be the best it can be.

If you can't live read what AFR your FAST-EFI is putting out, an inexpensive wideband is a good idea, AEM UEGO, Innovate LC-2; nobody wants to make WOT power at 14.7:1

It just might change your life! :D
