Re: 66 Galaxie 500 XL upgraded with 460 engine
Threads old but I hope this info isn't too late...
The above info is FALSE! There is a ton of misinformation on the internet that continually gets repeated about the engine weights. The 460 is a newer LIGHTER design then the FE's. I think the problem with those published weights is how the engines were weighed, some with exhaust manifolds, water pump, carbs, even all the accessories, some without, some with various combinations.
I dropped a 460 in my '67 that was originally a 289, I bought standard 390 springs and the car road too high and just a little too stiff.
I eventually dropped on aluminum SCJ heads and Edelbrock intake and needed to cut somewhere between a half and 3/4 coil off the springs to get it down.
Eventually I wound up selling the motor to a friend, on his way home with it he stopped at work and weighed it, carb to oil pan, fly wheel to water pump (no headers/manifolds) it weighed 518 lbs. I know for sure the heads saved 35 lbs each, Ford SVO's claim I also verified myself) and I'd guess the aluminum intake saves 20-30 lbs. That puts an all iron 460 around 625 lbs.
