I was just reading Kevin's response to a writer about a gen 1.5 block(350)not having a bypass hole from the RH deck to circulate water back to the RH water pump flange. here is my question. I am building a motor for my 91 vette using the 14093638 block casting. Does this block have that issue? Getting ready to button it up and want to take care of this before I do if it is necessary.
Who's Kevin, which Post are you refering to. Gen.1 block ? not familier w/1.5 block. Is this a reverse flow/head block?
