I will be rebuilding my 75 F100 this summer and would like to get a little more power. I've read where you can use a 428 crank to get 410 cubic inches in a 390 block. Since the blocks are the virtually the same (360/390) can I use a 428 crank in a 360? Do I need to use the rods and pistons from the 360 or use the 428 rods/pistons? Are there any issues with the clearance on the bottom of the cylinders, etc. Any help appreciated. Thanks

 

......Neither. You need 410 pistons, and 390 rods.

 

I thought the bore was the same, just crank and rods to get the 410cid ?

 

You're exactly right. .....however you need a piston with a lower compression height. A 390 and 410 use the same rods. So...in order to keep the piston below deck, you must change the pin location.

 

Ahhh, gotcha, thanks

 

When I bought this truck the previous owner told me when he last rebuilt it he put in a 390 crank and pistons, thus making it a 390 (bore was the same), I'd like to take it up to 410 with the 428 crank if I can, just wondering if anyone has made this change and what I would need to do.

 

Once again.....You need a 428 crank, 410 pistons, and 390 rods. Balance them as needed, then assemble. It's that simple.

 

Thanks!!! That's what I needed to know.

 

The 410 is a factory configuration......so no other modifications are required. There was also a 406, which is 428 bore with 390 crankshaft.

 

It was a mercury engine, correct? so a 410 was an fe block then. I wonder what she performs like in a stock config

 

One more thing.....you'll probably need a 428 flywheel. But just worry about getting the crankshaft, pistons and rods. Then your engine builder can make sure you get everything balanced properly.

 

Yeah, it was a Mercury engine. My dad still has really late 65 model year Mercury Monterey Marauder that came with the 410. I thought that was weird because i thought the 410 came out in 66. I guess it did, but a few late 65's have them too. Also, the Merc 410 is not to be confused with the Edsel 410....way different monkey there, if I remember correctly.

 

You can use any flywheel if the entire assembly is getting balanced.

A side point... most 360 engines use 410 pistons.

So the recipe is: 410/428 crank, 390/428 rods, 360/410 pistons.

That is neat ive never heard of a 410. A shame it works out that way, i would assume the 360 rods are longer. Longer rods make for better torque not sure what the difference will actually yeild tho.

 

THANX - MUCH INFO here - will be "building" a 360 later - - was going to "build-up to a 390, but may change plans, to 410. Need to get thru this snow/rain weather 1st. Don't need a racing mill buit the added HP will be nice. "Overkill" for an old 250 SC. LOL
