5.4 iron block

Anyone know where I can source a block. Seems Ford discontinued the iron block. Sucks because I have one but the cyclinders are out of spec for my rotating assembly and I already got it balanced. I thought I had one from Cj Pony Parts but it didn't work out. Any help will be greatly appreciated.

I don't think there's any difference between the iron block in a GT500 and the iron block used in all 5.4 trucks. You may not find new, but there's got to be used blocks in abundance.

Not sure this is what you're looking for, but Johnny Lightning Performance would have a 5.4 if anybody did. He was building about 300 per year at one point.

Pretty sure they are the same.

I mean wait scratch that, everyone knows Ford mixed unicorn blood into the castings to make the motor more magical.

The GT500 block is discontinued. The 5.4L truck block can be used but does not have a freeze plug in the water pump pocket like the Shelby. Ford does not offer a plug of the correct size, we had to source one and trim it to fit. However the truck blocks are also on a national back order. I've had several on order since June and they keep getting pushed back 2 weeks every time I call Ford. They do have a note stating over 3,000 units have been shipped from the supplier. Who knows when the blocks will go through inspection, final assembly, and crating ready to ship. (holding my breath...)

Looks like I'll have to get the aluminum one.
