Exhaust line up

[will]

If i were to swap a 383 for a 440, would the exhaust line up or will i have to tweek the system? I'm just trying to figure out if i'm going to have to buy more stuff. This is with shorty headers.

Probably will require some sort of work to the headpipes where they connect to the headers, might have to lengthen them some since you are going to a RB engine which will raise the exhaust port locations in the engine bay.

Wider too.  If the head pipes have an H pipe welded in now, it will take some work to the point you might consider new

I really don't want to replace the exhaust if i can, but if i have to i guess i have to. I guess tti is getting some scratch after Christmas.
