I believe these are truck manifolds.

Looks like a 454 Police Package 73-76 model year era. Your 3394045 is PROBABLY a 3994045. Only problem is the chart below shows them both to be left hand. Usually EVEN numbered parts are Right Hand and Odd numbered parts are Left Hand so I believe the chart SHOULD read RH on the 353030.

Hey Thanks, the left is a 3994045. Where these are off of a police cruiser do they flow any more or less or are they the same flow as the 67 ones on my Camaro? Thanks for the info.
