I have a 71 t-top with a 350/270hp engine.  I need to replace the passenger side exhaust manifold.  The casting number is 3989036.  I need one without the AIR holes.  I'm having a lot of trouble finding one.  I ran accross several with the casting number 3932461, which is the 71 350/330hp LT1 engine.  Will the LT1 manifold work on my 350/270 engine ?  What is the difference between them??
