Customer q:

I would like to know if the big block 454 product #809-12568774 will fit in my Cadillac Fleetwood. It has a HT4100. I want to swap it out with the 454 and swap out the trans with a new TH400. Thanks.

Thank you for giving JEGS the opportunity to assist you with your technical question. A Chevy big block physically could be placed in your Fleetwood, but you will have some fabrication work involved to complete your swap. Should you need further assistance please feel free to contact us.
