have a 61 starfire and was wondering if a 394 out of a 64 will match up with the exhaust manifolds in the 61. Also, will the motor mounts be the same. Thanks

 

Here is a link to a related subject, it may not answer your question completely but may help.

note in particular the statement in the third post.

 

Are you looking to adapt '64 manifolds to your '61 engine or vice versa?

Well-done Starfire convertibles are becoming high-dollar collectibles, especially the earlier models. In the interest of preserving its value I would make every effort to keep the car as original & correct as possible, unless the car is a complete beater. I've seen several otherwise nice '61 & '62 Starfire convertibles for sale over the years with incorrect engines..... and drastically reduced prices.
