Sorry, I should have added that the highway patrol told my dad that the motor ( my dad said that they just checjed the block number, but I do not have proof) was a 5.7 out of a 91 Z-28...I can not find a reference to casting code CLP except for a 71 400....That is what I am trying to find out....
what motors do the casting code CLP apply too....
thans again for the help
