So, if a 6.91 on pump gas was such a big deal, then I guess it was a big deal. |

In the late 1970s when all the oil companies did away with premium fuel of any persuasion, I got my 12 to 1, 428 running in my dirt track car. I was so impressed with the new MOROSO octane booster that I tried to run it on 89 regular fuel with the appropriate mixture of what MOROSO recommended. After the 20 lap feature race, which I never finished, I pulled in with pits with smoke billowing from the breathers. I ran about 17 laps of the 20 lap feature.
Upon tear down I had torched a hole in one TRW 12 to 1 piston, and seriously caved in the remaider of the crowns of every other piston. The fresh engine had aluminum all through it and needed a complete set of new pistons as well as rings, and bearings. I never tried that again, after a call to Nunzi,(when he used to help people over the phone in the evening) He told me to find a set of smogger 400 heads and run them to lower it back down to a reasonable level. Found a set of 71 400 heads, lowered the compression and ran the car for 2 seasons without a hitch. Now that's my true story about running a 12 to 1 engine on 89 octane fuel, it lasted about 30 laps, an expensive lesson learned. |

I had a Crane roller that was made in 1969. It was a low lift high duration cam. I had it in at 112 most of the time. I still have the old camshaft too.

I could see that being a recipe for disaster. Totally different scenario than mine was. |

And diesels like detonation far less than gasoline engines. Used to get injectors time to time out of EMDs (4,500 hp) that suffered detonation due to low cetane; “ugly” doesn’t describe what they looked like internally. My BIL did that with his brand new C2500 Duramax. He got five miles before the engine shut down. I castigated him because back then (2006) new injectors for a Duramax were $1,000 each.

Not sure what the big deal is about running a 6.91. My old school, old junk 455 ran a 6.80 at 9.3 to 1 CR. A real pump gas engine. |

I freshened it up every winter, and never lost a bearing over 5 years. It was a toy, and it was stupid to put race fuel in it all the time. As for it being a “big deal”, I’m not the one that acted like 6.60 in a 3680lb car was all that impressive in 1994.

6.60 on pump gas was easy for some back in 94 but 6.60 was difficult for others in 1996 running NMCA ..... This is a post from John Langer. He was running 10.50's at the time

Those cast iron core Crane Cams rollers from the 60's were ideal for high mileage pump gas combinations back in the day.... They never wore out.

Who ever said anything about running 6.60s on pump gas? Also, I didn’t realize that everything was based off of John Langer in the 90s.

Well, I have one with a lobe wiped off. Race fuel would’ve probably kept the rocker arm tight.

Next thing I know, you guys will tell me it didn’t have working AC when it ran that fast.

Let me get this straight.... The engine was together for five years. You drove it almost daily. You didn't care if it blew up and you freshened it up every winter.... __________________ |
