Engine swap question?

[Joel86Cutlass]

Hey guys any help you can give me with this, or if this has been covered before point me in the right direction. I have a Pontiac 455 out of a late 60's car not sure what and want to put it in a 84' Cutlass Supreme. Any tips on motor mounts, headers, etc. Thank you for any help.

Pretty sure Blake did the Olds 455 swap, he is asking about Pontiac.

Questions would still be valid though 😉

Yup, I went Olds 455... 8)

The Poncho motor will work, you'll need a set of 301 motor mounts to drop it in.

Headers I'm not sure, I think shotgun would be able to fill in the blanks better than myself.

First off sorry for placing my post in the wrong area. I do have the 301 motor mounts so that won't be a problem. Once again thanks for all your help.

Not really. The Pontiac and Olds 455 motors are completely different. The only things they have in common are the bellhousing bolt pattern and the distributor.

I understand you have the motor, but putting in a small block chevy will make you happier unless you spend some bucks on that Poncho mill. The rope rear main seal is a JOKE, the conversion kit is expensive. The heads are terrible, flow, port design, combustion chamber, they make decent boat anchors though.
