The Engine

 Engine after the rebuild. Lots of detailing… And I don’t think the engine was this clean ever again…

This is a 1965 289 cubic inch engine making about 275-300 horsepower at the flywheel (bhp). She sports a complete rebuild with the following installed parts:

  • High performance 289 block and heads

  • Block bored .030 over

  • Block decked .010

  • Flat top pistons installed providing 9.8:1 compression

  • Larger Manley valves in the heads with hardened seats

  • Crane Cam with 204/214 at .050 lift

  • Edelbrock dual plane manifold "The Performer 289"

  • Holley 600 CFM vacuum secondary 4 bbl

  • Hi-Po 289 exhaust manifolds

  • Duraspark II distributor with a late 80s Mustang distributor cover

  • MSD ignition

  • Plymouth Roadrunner “meep meep” horn

    After the restoration I made a few small changes to the engine:

  • Installed ceramic coated Hedman 88400 headers with a new exhaust system

  • Replaced the Holley 600 with a Barry Grant Road Demon carb

  • Removed the Road Runner “meep meep” horn as I preferred the stock dual horn sound.

  • Add a Falcon export brace and cut out the stock engine braces

The car also was upgrades from a C4 automatic to a T5 5 speed. After these changes above were completed the car’s engine really “woke up” and there was a noticeable change in how the car pulled through the gears. If I could do it again, tho, I have to say that if you have a manual transmission in your car, or are planning to, plan to upgrade the cam to something a little more aggressive as these lower duration “RV” cams really have the engine run out of breath around 5000… Which you notice more with a manual transmission. with a late 80s Mustang
