- 66 cadillac commercial chassis hearse
I am actually in the process Help putting in a Gen. 5 4 54 in 66 Cadillac Fleetwood Fleetwood hearse. The 454 is about 60 pounds heavier than the 429 The steering length is an issue you have to have front sump and it's just a hair whiter than the 429 I'm gonna have to make headers or get centre dumps. The 454 Is out of an 89 Chevy Silverado 3500 Using the TH 400 from the truck changing out the tail shaft from the Cadillac definitely have to change out all motor mounts.
