Can you put in a 428 Crank, rods and pistons in a 390 block by just boreing it .080 ???

 

Also what pistons do I use if i don't want to overbore?

 

.080 over is too much for most 390 blocks. Have your block checked to see if it will handle that.

At 390 bore of 4.05 or at .030 over 4.08, you can build a 410 using the 428 crank.

Use the search feature in the FE forum to find more info on these builds. It may require 428 rods and custom pistons.

here is a good thread on 410 pistons. I found many threads just looking for 410 in the FE forum over the past year.

So if i keep the 428 crank and rods what pistons do I want?

 

Someone said 1976 Ford Truck 390 pistons?
What is diferent about these? Can you get them New?

 

The other thread describes the pistons I was able to find.

What you want is 410 Merc pistons. (which were also used in late model trucks.)

Trouble is thay are only readily available in cast.

If you want forged, your options are either "Custom" (Ross catalogs one, but its basically a catalog custom) or machining a standard 390 piston.

360 or 390 pistons wont work?

 

Look for a D3TE block used in some 73-76 360/390 pickups. The block has the thick main webs similar to the 428CJ block. It also has thicker cylinder walls than the standard 390 block. We have successfully bored several customers D3TE blocks .080" over (428 standard) without problems. If you are unsure, have your shop sonic test the cylinder wall thickness.

 

Getting frustrated trying to get more Cubic inches.
Should I just by a stroker kit?

 

That's a possibility, but FE kits are not as plentiful as 302 or Windsor based kits. Also, most FE kits we've looked at use aftermarket H-beam rods and forged pistons. Could get quite pricey!
