Re: EGR valve for SBC

[Len Sabatine <sabatine@epix.net>]

   Early to mid 80s Carb'd used neg B.P. Egr's. Many aftermarket EGR Valves
   have calibration  "washers" that insert in the pintle end that match 
EGR flow
   to the engine profile, thus these valves are "tunable . The opening 
rate can
   be an issue , sometimes it needs to be restricted as to slow the 
opening rate
   to avoid a tip in stumble. BW and Standard have OE x ref #s, which may 
help.
