Glad to hear everything went well and that you like the cam. That 2031 does pull like a mofo! Anyway, I would guess anywhere from .2-.5 gain. .5 might seem like a lot, but I have seen stranger things. I have seen an 86 AOD car gain .5 just from Cobra intake and 1.7's, so I would say you could see a gain like that also. Let us know how it goes!
