As long  as an 891 will crank to 6,000 I can live with  it. 


Hi Smitty,
None of my business but since you brought it up I'd be worried about  pushing 
an 891 cam to 6 grand. Especially a 140hp engine. The 304 cam was  especially 
designed to have longer ramps so as to reduce or eliminate MULTIPLE  valve 
seating bounce that Chev experienced on the 140s using the 891 cam. Also  the 
304 cam reduced valve float too. Losing the retainers on the lifters most  
likely means you have been floating the lifters. Thus telling you that you need  
either stronger valve springs or a cam with a better profile for your  rpms.
 
Were these lifters that lost the retainers normal Corvair lifters as  
pictured in the '65 Shop Manual? Or were they after market-type lifters? 
 
HTH
 
Regards,
Bob Helt
