L86 Intake swap questions

[53boy]

Mods if this is in the wrong section please move

 

I had a couple questions for you guys who have done this swap. 
 

- is the foam under the intake still useable with the 6.2 intake manifold?

- are the pcv / crankcase lines routed the same with the 6.2 air cleaner , wondering if my 5.3 lines would clip right on to a stock 6.2 air cleaner 

 

- is the 5.3 and 6.2 air box outlet the same diameter? 
 

- any issues with relearning? Could someone talk about the relearn procedure 

 

- did any of you guys run into any issues on the stock tune? I am planning on getting a tune soon. Aiming torwards Black Bear 

 

thanks guys!

didnt relearn since truck is already tuned, the intake tube wont fit the size and angle of the tb are different, I just bought the air raid tube for the 6.2 It comes with the valve cover fittings. You can just use 3/8" vac line for the crank case one, or buy the actual fitting. I didnt even try to mess with the foam just slapped intake on

The 6.2 stock intake tube won’t fit ? Why’s that? I’m trying to figure that out 

 

what brand tune are you running?

sorry meant the stock 5.3 tube wont fit the 6.2 tb
