whats wrong with the 428?
My 390 is smoked im gonna get a re-man from precision engine they list a 428 for 1200 +500 core they wont take my 390 as a core.The 428 should bolt right up to the fmx cast iron tranny but what about engine mounts?I never see the 428 talked about as much as the 352- 390- 427. WHY?thanks for any advice. maddy

428 is a direct replacement. It is a fantastic option, and actually does get quite a bit of forum time. By ownership, the engines in this forum are probably from top to bottom:
360
390
352 (Many think they have 352 because its cast in the block, when in reality it's a 360 or 390)
428
427
There is no reason not to use a 428.

Maddy:
The engine mounts will work just fine. The issue you may have is in the balancing of the 428. The guru's will correct me if wrong, but the 428 was externally balanced at the flywheel/flexplate. The normal recommendation is internal balancing or grabbing the flywheel/flex plate that was once associated with the 428 engine. Check to see where your potential purchase is balanced and go from there. The 390 probably won't core as there is no guarantee that your 390 block can handle a 428 bore, just a guess of course...

True. I forgot about the need for a 428 flywheel. The other option is to have your machine shop do an internal balance. It is done all the time. They just add heavy metal to the crank during the balance process to eliminate the need for the special flywheel.

Just a heads Up- its best to have any engine Internally balanced at the shop thats buiding it anyway... that way you never have to worry about a flex plate or harmonic balancer..ever again..and internal balancing is more precise than external...
Good Luck Russ..

If that isn't the truth I don't know what is. Wouldn't it have been nice if ford started using the 428 in trucks to give them a little extra torque. I guess the 390 wasn't short enough on it to justify doing that.

Russ, are you drinking again? (assuming you ever stopped)
As for my mileage, I'll start tracking it. I finally got my gas gauge working right! I filled up the fuel cell, and it went right to the "F" :-) I've got a shop full of sending units and gauges if anybody needs anything :-)
I agree, nothing at all wrong with a 428, except it's availability!

Concerning 428's, my opinion is this:
Just buy the 428 crank and build a 410. Much cheaper than tracking down a 428 block. If you must have a 428, find a 360 block that will take a .080" overbore and go from there.
I am surprised more people aren't building 410's on this forum.
