[Roadsters] Bell housing front cover question

[Paul]

Dewey,

  Yes, the 1600 and 2000 have different thickness plates between the tranny
and block.  And yes, the clutch won't work right if you use the wrong plate
(And yes, at Sloan Racing we have had to pull motors back out of the race
roadsters because we grabbed the wrong plate!).  But I can't remember which
one is thicker?

  If the 4 speed is still a bit high in first, remember you can switch to a
3.90 ring and pinion from a 1600.

Subject: [Roadsters] Bell housing front cover question

Hi all, I am planning to put a 4 speed tranny behind my 2000 engine for
improved gearing for autocross.  I have read you must use the correct bell
housing front cover, for the tranny you are using, if you swap trannies on
the 1600 or 2000 engine. Does anyone have the thickness measurements of the
different front covers for the 4 speed and 5 speed trannies?

I recall reading something about different thickness front covers cause
increased stresses on the throwout or transmission bearings.  Does anyone
know the specifics about that, or any other reasons for being careful with
the front covers?  

TIA, Dewey Hahlbohm
