If theyre Crower's thats excellent!! You should have put that on the title Greg, might attract alot more attention that way. I see the Crower on the bolts now, but I would still wonder lol Gotta make sure to disassociate from BC for something like this.
I say 1500hp is a big claim only for that reason...not too many folks here (maybe a handful) are making 1000 let alone over 1000, so its hard to say anyone has proven them, etc. Not saying its impossible or anything like that. I agree even if they can handle 1000 or 1200 its still a pretty good deal. The old Crowers were rated pretty high IIRC too, so if these are new/improved I would imagine them to be a solid choice for monster output engines!! Crower has a good rep IMHO.
IDK too many folks around here that will spend the money, but it'd be nice to see a build that uses/needs these.
GLWS Greg!!
