Water cooled SV cam ID / exhaust valve

[Bob L.]

Have a cam from SV engine...Older build/not run...supposedly a Engine Developments build (Brabham/Judd). Has stamping in end: SV B34 "B" led me to think a Brabham grind... isn't a 3 or 8....

Haven't tried to degree/check... Wondering if anyone recognizes the grind...who, specs (dur/lobe ctrs/ lift). Solid/big dia. lifter with shims under buckets...

Also, looking for an exh. valve to match others... head is 1.386" dia (35.2 mm), appears to be 8 mm stem -- stepped down under head, 4.058" long (103 mm)...single groove keeper. Don't know if something special or oversided a bit... measures big on head.... std. overside is typically 35mm/1.378" Think length is longer than stock...seems that might have been done with some BMW valves?

Thanks.

you might try to message Richard Wilkinson or Bob Morris - both out here in CA - on FB. They ran supervees for years on the west coast - all the way from the series in the 70s through vintage as of 2015.
