This is our Thoroughbred : forged pistons, rod and crank in a raceready
block. .The 427R is perfect fit for any project car and performs great on premium unleaded “pump fuel”. This engine, like the others offered, is “hot tested”, then dyno tested to verify power
In the history of Hot Rods and Muscle cars, the number”427” brings back “Magic Memories”. Back then, the “Side Oiler” was the King. Today, we have the option to build to this memorable cubic inch and still have all of the benefits of the “Windsor Engine”. By using the “Dart- Iron Eagle” 4 bolt main block, ’we accomplish the best of
both worlds: big cubic inches and dependability. This is our Thoroughbred : forged pistons, rod and crank in a raceready
block. .The 427R is perfect fit for any project car and performs great on premium unleaded “pump fuel”.
This engine, like the others offered, is “hot tested”, then dyno tested to verify power (and is shipped with
documentation) and carries a warranty.
