My engine builder is needing to know what type of oil pan he needs to install on my 383. I bought pacesetter LT's wiht Ypipe and need to know does the ypipe cross under the oilpan or further back? THanks for the help!!

 

If they are long tubes, then obviously the y-pipe will connect after
the collectors. Are you sure this person knows what they're doing?

 

I know they cross after the collectors! I need to know where exactly do they cross?? Under neath the oil pan or slightly past it??

 

Well, I dont have Pacesetters, but my Kooks y-pipe cross and
merge just past the transmission.

 

They don't even come close to the oil pan. They branches of the y-pipe merge more so in the middle portion of the car.
