428 Cobra Jet Engine

Complete fresh rebuilt, drop in ready, turn-key, FORD 428 Cobra Jet Engine. Cam selection was a Hydraulic Flat Tappet with Howards lifters and matching valve springs. Lift is .530 with a duration of .276. Will pull hard to 6000 RPM with a powerful sounding cam.
Heads are true 428 CJ C80E-N and were completely restored with new guides, hardened seats, retainers and locks with original Cobra Jet valves. Slight bowl work around exhaust valves for better breathing. Installed a new 428 CJ Crankshaft with Clevite bearings and used installed new Silvolite pistons with matching rings at 10:2 compression.
The cam works great for either 4 speed or automatic cars. Recommend a 1800-2200 stall for automatic cars. This application will significantly out perform the stockCJ engines. Not a real rough idle, has good vacuum as well. 🇺🇸You have a true 425 plus horsepower engine here 🇺🇸🇺🇸🇺🇸Video of the engine during camshaft break-in will be available to any potential buyers. This engine has mostly original FOMOCO parts. The block, heads, intake manifold, C7AE-B 13/32 bolt CJ Rods, Flywheel, pulleys, exhaust manifolds, distributor and carburetor are all original FOMOCO parts. The valve covers, water pump, oil pan, timing cover, vacuum lines, etc are aftermarket but fit and look great 🇺🇸.

All sensors are newThe block was cleaned and prepped with new cam bearings, freeze plugs, and oil galley plugs. This engine needs 500 miles of run time for the new Piston Rings to seat. Pictures of the engine show its progress throughout the rebuild.
I tried to ensure the details of this engine are correct and very well built. It was properly cleaned, inspected and assembled with attention to detail. This is a Turn-Key engine, ready to install. There are minor adjustments you need to do once installed like idle and timing etc…. I have plenty of references available for any potential buyer.
