1965 Cadillac Sedan Deville Need help- I have a ‘65 Cadillac Sedan Deville, would like to replace/upgrade the 429 engine. What would be the best option for fit and optimal horsepower given the size of car? I’m not hotrodding it by all means. Just wanting the power to get it moving without tearing it up and enjoying a good faster cruising car.
Your suggestions would be greatly appreciated

Almost any LS3 based engine would be best, for sure if you can afford an LSA either Cadillac or Camaro would be ideal. There are a couple of swap threads on here for ideas. Good luck with your swap.

79ls1fox thanks again
If money is not an issue, an LSA swap would be super cool, and keep it somewhat "Caddilac".

While a 5.3 definitely moves a Tahoe around... the extra .7 or .9 liters from the 6.0/6.2 is really needed for the extra torque. Add a medium size cam with long tube headers and gain over 75hp easily with a tune.

I have a 66 deville convertible. I'm trying to figure out thd motor mounts. The 429 engine mounts r toward the front of the block. And the LS mounts r more toward the center of the block.

my issue was the stock steering gear box took up a lot of room on the drivers side. There wasn't enough real estate for a header, gear box and motor mount. I had to use a motor plate instead of motor mounts...
