Any test these 2 on a 400+ inch motor? I think the SV should work better on a 340-370" motor up top, but I'm not convinced it would work better on a 4" stroke motor, unless somebody can prove it to me otherwise.

The old Vic has really short runners and with a HVH or Wilson 2" spacer ( 4 hole tapered for first 1" and then open below) seems to work really well on 408-414's with good heads.

I can't see the longer runners of the SV being a plus On a stroker but they may be a lot bigger cross sectionally, haven't compared them side by side though. The taper from the plenum on the SV looks pretty impressive though.

Any back to back tests and conclusions out there??
