Affraid of reversion, exhaust HELP?
Bbc 509cid, 9.7 comp, roller cam,230/236 @050", 112lsa. Dry section of the riser is now approx 15" longer than in normal riser, 6" taller + 9"longer. Is It possible to use the silent choice diverters? I could limit the water flow going thru the exhaust if needed. The line attached to inner transom assembly shows the transom line.

Atleast my engines showed signs of it when the top ends were rebuilt.

how would you guys reduce the water flow out of the riser? how big holes would be enough to keep things cool? i know this is been done thousand times but cannot find any threads about this subject. my cam has almost twice the overlap @ 050" compared that 500efi cam, dont want damage a fresh build engine.

Just a thought- take the risers to a skilled tig welder and have him extend the inner 3" pipe through the transom. That's what I did when I got tired of worrying about reversion.
