Hp manifols

[clazar]

Can anyone tell if 70 b-body hp exhaust manifolds are different from the 68-69 ones. I always see someone selling the 68-69 ones & not for the 70.

The 70' has studs on the driver side to attach a metal bracket type pipe for the warm air tube going to the air cleaner. They look otherwise the same.
However, the exhaust pipe pattern may be different, but I sold mine and can't compare anymore.

That's the only difference I could see on my 70 383 Challenger.....the cast in mounts for the hot air stove....and also can't help out with how the exhaust pipe mounted or even if it was clocked differently.
