Hey guys,
as both of our cars still have the original engines (BT5 60 hp and C 75 hp) and we still have two spare engines we are wondering what is the best engine block base (1600 a serie, b serie or c serie, 60 hp, 75hp or 90 hp), to go a little bit hotter.
We guess out here is enough experience with engine blocks and hp's (1720 ccm, 1800ccm, 1900 ccm or even more?).
we are curious to hear from the experienced once ...
cheers Helge & Bjørn

Hello Helge. For a "little bit" more power any large oil pump case is fine. For major power increases you should use the late B, C, 912 case that is the strongest of all.

Re: Built an engine >1600
C engine cases will have the 616/15 and 616/16 (SC)
912 will have 616/36 ('65-'67), 616/39 ('68), 616/40 ('69)
I need help on the B cases ...
These numbers are stamped on the right-side case half just visible in front of the fan housing.
