The reason i was asking was, Just make sure your rear end and stuff can handle the power of the new engine.

Power difference !!!, everybody knows that if the driveline has lived behind a 350 Chevy it'll have no problems with a 440 Mopar

J/K all you Mopar guys don't send the lynch mob after me

If your pan's sump is at the rear, you can use a truck pan and pick up tube to move the 440's sump to the rear, as a 440 passenger car has it's sump in the middle.
The oil pump to steering box should be looked at- oil pump is external on a 440.
What kind of vehicle are you thinking of changing the engine in?

You should always be cautious of being rear-ended while sitting on the side of the road waiting for the wrecker. Maybe some reflectors or reflective tape in a nice mopar color!

Big mopar fan here, but I think a 440 in a z28 is fair payback for all the old mopars forced to suffer under the yoke of a SBC 350... (Slow Broke Chevy)

Number one reason I've always heard was 350's are cheap and easy to get parts for.

Well if cheap and easy's what your after More power to ya.

Now lets be nice and agree to disagree.

Honestly I'd say the 440's more trouble than it's worth in this case. Do able, but if you decide to sell it later your going to have a hard time doing it for what you invest. Making it look right under the hood is going to be another issue.

Swapping in older cars is easier because there is less to deal with, more space, less electronics, fewer parts to work around, such as power brakes, and suspension.

You are looking at having to change motor, transmission, driveshaft, fabricate some kind of mounting system for engine and trans, Custom exhaust, Ignition system, Some way to hook up your speedometer, plus many other items you never considered, such as hooing a mopar starter to a GM system.

If you do it and pull it off great love to see it, but it's a bigger project than you may realize.

I believe your wieght distr. will be way off. It will be way front heavy. you might have to change the springs in the front end. You could probably do some major burnouts though. but I would suggest a Ford 351W But when it comes down to it you can do what you please.
