“You can’t make power with salvaged parts. Everything has to be brand new and cost a fortune.”

BET. 😈

This little SBC was built on a budget using a mix of carefully selected parts, good machine work, and smart planning. The result?

🔥 Almost 400 HP... and we're still climbing.

Turns out horsepower doesn't care how much money you spent. It cares about the quality of the build.

OK BUDDY. 🔧💪

Today we pause to remember and honor the brave men and women who made the ultimate sacrifice for our freedom. 🇺🇸

Steinhafel Precision Engines will be closed today in observance of Memorial Day. We hope everyone had a safe and great Memorial Day weekend with family and friends.

We’ll see you back at the shop tomorrow 🔧🔥

Spent some time at the Tomahawk Car Show checking out a few rides powered by Steinhafel Precision Engines builds 🔥

There’s nothing better than seeing engines we poured hours into out cruising, shining, and making noise where they belong. We appreciate everyone repping our work out there! Definitely made us proud to see them in the lineup! 🔧😎

We’re back for our regularly scheduled programming! 🔥

Needed a couple weeks to lock in and focus on getting some engines out the door — and the results were worth it. 👀

✅ The Pontiac left the shop making 489 HP / 519 TQ
(Started at just 225 HP / 280 TQ before we touched it 😈)

✅ The nasty 421 laid down 590 HP / 570 TQ
Just missed the “King of the Dyno” crown… for now 👑

Now we’ve got this little 350 SBC up next on the stand. Let’s see what she’s got in her. 🔧🔥
