I will be installing a 4l80e in my 2008 RCSB. I'd like to put headers and an off-road y on at the same time. Anyone had header clearance issues after a 4l80e swap?

Or is the pan and trans size pretty much the same?


Thanks,

Mike


*swap (typo in the subject)

 

Bout the only thing that will hit is the two ears on the bellhousing. I cut those two holes off the bell.

 

if you have Pacestters you will have to beat the y pipe flat on the top where it goes under the trans pan.... real easy.. beat the top flat with a big rubber hammer

 

My headers don't clear the ears on the bellhousing dust cover, but the stock exhaust does. Other than that, everything fits fine, Y pipe included (ARH).
