Dyno Tested 347-Inch Small-Block Ford Makes Over 500hp

Westech’s Steve Brule sends us over a very impressive Ford small-block they recently tested.

Aside from filming the super cool Engine Masters stuff at Westech, we do many of our engine build tests there, too. But even with all of that, the guys at Westech stay busy testing hundreds of cool engines that have nothing to do with MotorTrend.

Engines for boats, car, trucks, off-road racers: You name it, and it shows up at Westech eventually. Some of the engines are pretty high end, while others are basic, but they all share the same goal: to validate the build, get some tuning done, and make sure they are rock solid before being installed into whatever they are going in.

So, we asked Engine Masters guest and all-around dyno guru Steve Brule to send over some snaps and info when something cool rolls into his shop. This time around, it’s a 347-inch small-block Ford built by Dales Restoration in San Bernardino, California. It’s a solid build with good parts, including AFR 195 aluminum heads and a MSD billet distributor.

As Brule told us, “The builder did an excellent job in choosing components, and I knew this was going to make some great numbers. The eight-stack injection scares most tuners,but with the high quality of the Borla injection, and the Holley TerminatorX , tuning was relatively easy. Granted, while being a system best left to professionals for tuning, it’s killer in looks, and the performance proves it’s worth the extra effort.”

After being slung up on Westech’s Superflow 902 dyno, the mill was fitted with a set of their 1.75-inch Hooker dyno long tubes and filled with Lucas oil. The block is from Dart with 4.125 bores and a forged SCAT rotating kit, along with JE pistons for an 11:1 compression ratio.

The customer brought in their own ECU, this time a Terminator X from Holley, so that there would be a good base tune locked in once the engine drops into the project car.

All-in-all a solid street package. And because it’s a street car engine, the cam is relatively mild at 223/230 duration (@ 0.50-inch) .598 lift and 112 LSA. The best pull ended up being at 34 degrees of timing.

As Brule recalled, “The engine made 1.29 lb-ft per cubic inch. I generally consider 1.25-per inch a high-end target when evaluating a given combination for 91-octane street engines. This thing is just plain stout. 449 lb-ft and a touch over 500 hpisn’t at all common for just 347 inches, especially with a camshaft that is only 223intake duration and only 6,500 rpm. I’m scoring this one a 10.”
