427 Small Block Ford Nitrous Engine

Engine Builder shared this 427 small block Ford nitrous engine that was built for a 1965 Ford Falcon bracket car that belongs to a customer of Brian Hafliger.


A customer came to IMM Engines seeking an engine that could run 5-second 1/8th-mile times and build to 650 horsepower. Shop owner Brian Hafliger got to work on this ride with a Dart SHP block built out to 427 cubic inches with a SCAT crank and H-Beam rods, CP pistons and Trick Flow cylinder heads.

Here’s what Hafliger had to say:

We used a SCAT 4340 crank with a 4.000˝ stroke that was internally balanced, as well as SCAT H-beam rods with ARP 2000 bolts. Most of the SCAT stuff will handle 1,200 horsepower and we’re below that. I’ve used their stuff a lot and I’ve never had a problem with it.

Hafliger delivered a 427 small block Ford capable of nearly 700 hp N/A and 1,000 hp on nitrous.
