I will call Ernie or Don monday and get a high speed by pass valve coming and hook it in. The only numbers on the injector nozzle pills is 35.

oops!!!,
Sorry Ray i was giving you a tuneup for stacks injection, a hat is a different animal. Are you running the nozzles in the manifold? as in 8 nozzles if so the jets may not be too. The barrel valve setting is also different on a hat than on stacks injection.
I appolagize for that mis-conseption it's just when i hear hilborn it usually means stacks unless it's a blown situation.
Don Enriquez, can help you on this one, i don't know much about running hats except in a blown alcohol appliation. I do run dropin pills on my blown engine in the manifold but also about 40% of the alcohol goes thru the blower and the bal. into the manifold.
