This guys ad is deceiving. It's actually a 390 FE block, but 428cid.

FORD 428 COBRA JET FE - $6900
428 COBRA JET
For sale is a fresh rebuilt Ford 428 FE. This engine is ready to drop in to your old ford muscle car. It has been updated with some modern parts and should make more power than a factory 428CJ.
This 428 started with a C6ME-A Ford block that was magnafluxed and bored to 4.130. The block was also line honed and surfaced.
The rotating assembly is a new scat 3.98 inch stroke Scat crank(stock stroke) with reconditioned Ford Cobra Jet C7AE-B connecting rods and Sealed Power 354p pistons. This is all neutrally balanced and blueprinted. It comes with the balancer and flexplate. The compression ratio is just above 10:1 and should work great with 91 octane pump gas. The top end Consists of C7AE-A 14 bolt GT Cylinder heads. The heads have been surfaced and hardened exhaust seats were installed. They have also been updated with new comp cams springs and retainers. A set of police interceptor rocker arms and new sealed power push rods were used. The engine is finished off with a custom Cam Motion hydraulic flat tappet cam (slightly larger than a stock CJ), comp cams lifters, a double roller timing chain, and an Edelbrock performer intake.
All high quality parts were used in this build, some parts not listed above include Felpro gaskets, Hastings rings, Clevite bearings, Milodon
oil pan, etc.....
This engine block started life as a 390. IT IS NOT an original Cobra Jet block. This casting number could have been used for a 360, 390, 410, or 428 from the factory. Because of this it is a block that has enough material to turn into a 428 and is regularly used to make 428ci FE engines.
I built this engine for an old ford truck project I was doing and plans have changed. I sold the truck and now I need to sell the engine. Please call or text with any questions.
I do not need help selling this and I do not take payments.
