What else req. for 408
My LS1 is done and I am going to buy a 408 short block and put the stock LS1 heads on for now. Is there anything I would need to buy for a 408 swap? Is the harness different or I heard knock sensors are different. I searched the site but didnt see any real info of needed parts for the swap.

no harness adapter necessary and you can reuse your knock sensors. i guess you probably already know this but the 408 will really be restricted with your stock heads. you going to go ahead and put in a decent sized cam for when you put on better heads ?

I did port my stock heads a hair though when i had them off, nothing drastic, but is should at least help with all that extra air coming in
Everything swaps right over, im in the middle of doing it right now, hopefully be done sunday
