Hey guys, could someone tell me what exhaust manifolds the 340 came with in 71'. Mine car was built in 4/71 and the engine cast date is 1/71. I don't know if they would have been the 68'-70' hi-po ones or not. Any information is greatly appreciated.
 
..........same drivers side mani.........pass side mani dumps in the middle........kim....

I agree

I believe these are the casting numbers a 71 340 A body would have.
Pass Side 3418623
Drv Side 2863553
 
Thanks, I was getting some information that they could have used the hp's since it was built so early in the year.
