Hi I have a 1967 Firebird that has a SBC fitted. The Chevy needs a rebuild and I would like to fit a Pontiac 400 instead. Pontiac engines are like hens teeth in the UK and not cheap. My question is what other things will I have to change if I can find a Pontiac that I can afford. I know it will be different mounts and transmission, but what else would I need or can I still use the Chevy alternator, power steering pump, brackets ect. Thanks Mark.
The Chevy alt will work, but will need Pontiac brackets. The power steering pump will work, IF you can modify the brackets to bolt up to the Pontiac heads & line up with the other pulleys. You'll need all the correct pulleys for the Pontiac engine.
The Chevy trans will work, by using a simple adapter plate, made to mate Chevy trans with BOP engines.
ALWAYS good to hear that a fellow Pontiac guy has decided to put the real heart back in their car.
BEST of luck, keep us posted and welcome to the herd!!!!!

God Bless the men and women past and present that have served this country. Thank you. Support D.A.V. - it helps gives a life back to those who gave so much for us.....
I Have found a Olds 403 for sale with a 4 speed box. its 79 block. is this worth considering ?
nope....and if after 71 year, consider any GM engine needs new heads and rework to have any power....I had a 72 Pontiac 400, but changed out heads and milled down to get a good CR....
