BluePrint Engines, the company that has redefined the term “crate engine” by producing its own engine parts and blocks, announced the reintroduction of the iconic small-block Chevrolet engine from the 1970s.
GM produced the 400 cubic-inch Mighty Mouse engine, the largest displacement small-block Chevy engine, from 1970 through 1980. Known for producing gobs of torque and power, the 400ci small-block rapidly became a favorite with racers.
“Our customers have been asking for a small-block 400 for a long time,” said BluePrint’s Dru Freese. “We decided it was time to bring this engine back after a hiatus of 35 years.”According to Freese, “Our 400ci engine is designed from the ground up exclusively by BluePrint Engines engineers using modern manufacturing processes.”
With a published 460 to 508 horsepower, the BluePrint 400 possesses far more horsepower than the original GM version. “These dyno-tested engines aren’t your grandpa’s 400,” said Freese.
These high-output engines were developed with automotive enthusiasts in mind who are looking for the combination of a new precision cast iron block coupled with all new components.
Each engine is shipped with complete individual dyno test results showing the horsepower and torque output. If that isn’t enough, BluePrint Engines backs their crate engines with a 30-month/50,000 mile warranty.
