Will BB headers work on a SB?
Got a cousin who's building a BB to put into his 69 Cutlass but wants to run the 350 thats in it for now with headers and new dual exhaust. He has headman BBO headers to use and doesnt want to have to buy a new set of SB headers if the BB pair he has will work.

 

They will hang way too low and there could even be issues with other things. He should just wait for the headers until he gets the 455.

 

Hanging too low is the least of your problems. More likely the headers will hit the crossmember, steering shaft, or starter.

 

the big block headers do that anyways.......
