You guys will laugh at this but I will ask none the less: just how much lighter is the 351 engine/tranny combo??

Suppose you modify the motor mounts and nestle this pair into your Squarebird. As you unhook your engine hoist and stand back... you realize... the nose of the car is alot higher than it used to be . . .

Just curious . . . .

It depends on how much aluminum is used. The 351 is usually married with an aluminum AOD or AODE. The bell housing and trans case are all aluminum.

The 351W comes in a variety of configurations (Mustang, truck, Crown Vic, etc.). For years, these engines wore aluminum water pumps, intake manifold (or mass air), and aluminum heads are very available.

Not only will you save 300-pounds weight, but the engine engineering is more advanced in a 351W setup w/any overdrive trans. No, they don't use overhead cams, but they can come with roller cams (Ford Lightning blocks). New Ford 351W crate engines are insane, with aluminum blocks and four-bolt mains. I have lifted a bare aluminum block over my head with no difficulty.

It's very easy to lower your front end, John. Less weight equals better efficiency, and we still go by horsepower-to-weight.

By no means am I suggesting everyone run out and change powertrains or alter your steel. I believe classic cars should be appreciated for what they were intended to be. Having said that, I also believe classic cars need to be safety-updated if they share our highways with today's cars and trucks. It's your car to enjoy the way YOU wish.

Love the idea of dropping 300#, which is not far from 10% of the entire car, just was wondering if, like alot of modifications, it begins a ripple effect of changes to get the car configured properly again.
