Is that a blower drive pulley of the front of the crank?

   Is it still common practice to set cam timing one or two degrees advanced for
a street use engine to allow for a bit of chain stretch or just to pump up low end torque?


Mike.

  As I understand it combustion chamber turbulence (call it CCT) helps promote flame propagation and reduces total spark advance requirements. Barney Navarro once told me that flathead Fords only wanted 18-22 degrees total because they had an extremely turbulent chamber. This leads to my question, modern chamber and coordinating piston shapes seem to have very little squish area which would tend to create less turbulence thus slower flame travel thus more spark advance requirement. I know that this is not the case so how do these modern designs create such rapid flame travel?

   When 347 small block ford stroker cranks came into prominence we saw quite a lot of talk about stroke to rod length issues because this combo had a very short rod and engine life was a concern. Might be why not so much being printed these days. IMO.

  Do the old rules about critical piston speed still apply? Seems I recall John Kasse running something like a 4.750 stroke in a four cam ford in the EMC and it really liked to rev. Piston speed at a given rpm must be very high with that much stroke. Yes,no?

   Thanks for the feedback guys. My lawn mower will love this stuff! 

    The July issue of Camaro Craft, sorry, Car Craft Magazine has a 427 FE build. In the article they show a one piece rear main seal from Roush. Has anyone had experience With this part? And how do they get it over the crank flange?

    Will a later model ('63-'64) Galaxie electric wiper motor physically fit a '60 Galaxie given the correct switch? I don't think my old vacuum motor will work well with a cammed up engine. Comp. 282s 433 cu. in. single plane.
