sorry for the lack of info, i woke up at like 3:30 am and when posting this i was almost completely out of it..lol
the 75 GMC had a 350 in it.....the 75 chevy had a 350 as well...here is the exhast from the 350 engine i took out of the chevy
and here is the "y" pipe that is on the GMC......im not sure if they are the same.
and here is the throttle cable...seems to long for this engine? is this normal legnth of these?
and the oil pressure line im talking about is the one that comes out from the firewall, and connects to the block just behined the intake, near the distributor....its way to short....i guess ill have to rig something to extend the line.....
