In this week’s episode of the Rottler Featured Series we visit Borowski Race Engines in Joliet, Illinois where they’ve been building high performance LS and Big Block engines since 1968.

General manager Ken McCaul gives us a tour of the shop and shows off their suite of Rottler equipment which includes an F68A 4 axis CNC, an EM69, an H85A hone, and an SG9M seat and guide machine Ken says they’ve machined over 15,000 cylinder heads on over the past few years.

Ken says what makes Rottler machines so valuable to his shop isn’t just the precision machinery, but the education Rottler offers that gives his guys the high quality consistency and repeatability Borowski needs to maintain its industry leading standards.

For our 10th episode in the Rottler Featured Series we went to Stone Park, Illinois to see how father and son team Andy and Andrew Frontzak of Engine Rebuilders and Supply are using Rottler machines to help rebuild classic and muscle cars to better than new.

Their shop opened in 1973 and they got their first piece of Rottler equipment—one of our classic green machine boring bars—back in 1983.

Since then they’ve acquired several Rottler machines, including our state-of-the-art H80 series fully automatic hone which Andrew credits for letting a small shop like his do what only bigger shops used to be able to do.

“The Rottler Hone lets us make the most power possible unattended. We just set it up and it does the rest.”
