Ofna force .25 help please

[silverbird02]

I got an ofna force .25 (or so it says on the head which can be changed)the bolt hole dont line up for my BB mounts that i got front to back or side to side took it to my LHS and was told it is a BB for a revo swap.But it requires a speacial BB conv kit.Which makes no sense to me cause if its a kit it should fit any BB...Right?well anyway it also says 3.5 on the CC which tells me its a .21,but if any of you have any help for this or have seen this engine type before LMK thanx :\

Sounds like the old OFNA 21 maxx that isn't made anymore. Was replaced with the 26:

The .26 uses this mount, but it's for the t-maxx only:

What vehicle are you trying to put it in? The exhaust port is also probably too small if your trying to use it in place of an actual big block. It was intended to use with traxxas headers.

I know the ones you are talking about and they are small block measurments with bigblock power i have a JL red dot on my T-Maxx(awesome)but this one is all big block including exhaust port but the mounting bolts dont line up with my savage MM,Thats why i have asked for help on here to see if some one knows what it is.Thanx for the input though.Still looking for answers.
