So I'm  looking for some advice on my next motor  build its a street & strip engine based around parts I've been collecting
so I have
74mm CB crank
Street Eliminator (42 x 37.5) 94 bore
94mm a spec pistons
Fk87

My questions  is it best to run a set of
Cb Super Race Rods - VW rod journal - 5.325"
Or
Cb Super Race Rods - VW rod journal - 5.400"
With barrel spacers
On this spec
 
Cheers Rich

With that short stroke you could use the short rods with good results, the higher piston speed/accelerations give good cylinder filling, but why only the 74 stroke? just  Be sure to check piston underside clearance on the crank webs at BDC ,

Yeah because you're going to notice the .075".  Use whichever ones you can get cheaper.  unless you're hell bent on making your motor .150" narrower.
