The "Mistake" That Changed Pro Stock - Roy Johnson on Hidden Horsepower 

Allen and Roy are down to earth guys, not uppity and arrogant like some are. They really gave the Mopar guys something to be proud of.

Mr. Johnson is the reason why I build Gen 3 Hemi's today. The work he did on the ProStock circuit is second to none. Thank you guys for providing this interview. He is one of my all time favorite Engine Builders and Crew Chiefs.

Met Roy and his Wife at a race years ago. Some of the nicest people ive ever met.

I know the emotions Roy is feeling since I had a heart attack 2-1/2 years ago. We are both still here thanks to modern medicine and the man upstairs. The Johnsons were and are good people and it's to bad they are not still out there racing.....

I absolutely love Roy and AJ really miss seeing them in Pro Stock we need that rivalry back.

This was an excellent interview Roy is a legend in the mopar community!

Mopar Family No Doubt about that

as always awesome. just like the dodge boys the AJ boys & Roy were awesome.

Bob's Boss 429s forced GM to develop the DRCE and THAT changed pro stock forever. The end of actual pro STOCK.

The Lights he Saw after were Win Lights ! Man I wish he could help another Allen these Days.! Great show guys !

we all miss the mopars in PS. I miss racing and most of all the people on the circut.

When Roy was racing AHRA at Kingsport he probably raced against Shirl Greer some. Shirl was from Kingsport and won the first race there.

This was an amazing moment!!!

I first went to a dragstrip in 1965 with my sister and her drag racing husband. So, I saw Pro Stock from the beginning. It was so nice having all four manufactures in the class. Now it is all Camaros and not nearly as fun to watch. Even the Mustangs run by the Quadra brothers not sure of the spelling, but their Mustangs are Camaro's under the skin. I was so disappointed when I found that out. I always pulled for Allen Johnson when he was running. Many say NHRA legislated those Hemi's out of the sport.

Roy and Alan are great people They tested are Chill Factor Hood & intake Cooling Blanket back in 97 & 98 for them to put Evert and take the time to test are products at that level of competition and then use them I can never thank them enough.

i talked to aj at gainsvill one day wayback when. it was after he was out.even then a sad allen was great.

This guy has a NDE and builds class winning motors after. Crazy!

Great interview. Learned while being entertaining.

I always remember they turned more RPM than any other team. I've heard they were in the 11,500-12,000 range.

You Gotta get Roy Hill on the show next

Back then the Mopars were absolutely dominant!

Love Roy and Allan. Great interview

I probably about Roy’s age and I also stopped drag racing because of the mid ‘70s gas crush … took off for 7 years. Oh my Penske Shocks

I wonder if he knew my grandpa who was a master mechanic for Chrysler for like 50 years. Last name was Bowdoin bowden. He did it all

When we lost Mopar and Alan Johnson😂 I haven't cared about pro stock anymore since they're gone pro stock hasn't been fun anymore

Before I was born 😂❤👌🇺🇸💪🏼

That generation of Americans are the greatest. They followed their passion today generation don’t know what their passion is 🙈🙈🙈

Allen and Roy need to consult with Demon 170 engine guys to figure out why they are blowing up !

so somebody please tell me,,,what was the MISTAKE ???

Long as it doesnt spin past 10k

please get better microphones the sound is like someoe talking inside a bucket

What?!?! You can run any engine in any car in Pro Stock now? Good grief, how bastardized is this class now?
