<VV> Heavy Duty Starter

[James Davis]

The stock starter will not turn over a 189.5 cuin high compression 
Corvair engine with a low performance cam (216 degrees @0.050 and 
zero degrees overlap).  Also, it will not turn over a hot (220 F oil 
temp) high compression (9.7:1), 168 cuin Corvair with 889 cam.  If 
the engine has 160 psi cranking compression the stock Delco won't 
hack it especially if the starter is hot.  The gear drive starters 
are lighter, stronger, and shorter.  Length matters in an Ultra Van.
