Kaase's Gallent Effort
Jon Kaase and the TIGER heads have definately put the traditional Pontiac engine back on the radar screen as contenders. Jon's strong showing this year at the Enginemasters Challenge with a Pontiac has certainly opened the eyes of the other competitors running a Chevy, Ford, or Chrysler.The buzz around the dyno rooms was they thought Jon had picked a looser for this years competition,and it would take a hat trick to pull it off. Well after Jon's first three warm up pulls, everyone there knew Kaase brought a contender. Jon's 509 Pontiac was making 630 plus ft. lbs. of torque at only 2500 rpm. One of the Primedia staff had made the comment that the diesel in his dually did not even make that kind of torque at that rpm. After the smoke settled and all of the competitors that showed ran, Kaase's Pontiac had pulled off the hat trick of the century for Pontiac enthusiast and was number one qualifier. Unfortunately for Jon and his wounded Injun, the finals were not so kind to them, but none the less everyone there knew that Pontiacs are back to play in a big way. Before I left I sat down with Jon to get his thoughts about the Pontiac engine and the new Tiger heads, and here is what he had to say:
DCI: Jon what is your opinion of the new Tiger heads for use in a street application? Kaase: The Tiger head is an excellent candidate for street use. Port volume is conducive to making torque at low rpm. Port velocity is excellent and with little or no porting on the intake port the head flows extremely well. The exhaust port can be run as cast and no port work what so ever. Intake to exhaust ratio is very good.As more and more companies start to develop bolt ons for the Tiger they will catch on in a big way for street use. DCI: What is your opinion of the Tigers for a race application? Kaase: The intake port volume is a little conservative for big inch engines or high rpm applications, but that is easily remedied with the proper porting. The exhaust would obviously need to be properly ported as well, but with the proper valve sizes and porting there is no doubt the Tiger is an excellent choice for a race application. DCI: How do you think the Tiger heads are going to impact the Pontiac enthusiast. Kaase: As more and more bolt on parts become available the ease of application will increase and the Tigers will be the head of choice. DCI: After your experiance this year with a Pontiac , Do you think you could have done any better as well with a Ford,Chevy, or Chrysler? Kaase: Absolutely NOT! DCI: If you were to build a Pontiac for a customer (IF) what head would you choose after looking at what is available currently? Kaase: If you want to make big power there is no other choice. Thanks Mr. Kaase for helping Pontiac enthusiast everywhere regain there respect among the racing community. Don Johnston DCI Motorsports, LLC |

I like that attitude- suddenly, 400 cfm is only a "street" head...

I think the news is great.
Remember that's a 509-inch combo with 400 cfm. Many in the community will not consider that a "typical" Pontiac street combo. I know Jon favors the small bore and long stroke combined with a relatively short rod. Now that the contest is over maybe they will discuss the combo's specifications. Anybody know the stroke involved? (4.500 w/4.310 bore would be just a tick over the maximum 510 allowed) |

Good job to all involved!
Looks like there is a lot of potential in the "Tiger head". Do you know what the failure was yet, and if so can you state what it was? Todd |

Thanks to Frank and Bob (Is that like "Neal and Bob?") of AllPontiac for actually producing this head, instead of standing around talking about it for years, as others did.

I'm more interested in the actual intake port/runner volumes and actual flow figures from the actual motor- let's face it- until you bolt the heads on, all motors are kind of the same. The heads are where the power is. |

With a 600-800" motor, "maybe" they need 700 cfm. 700 cfm on a 500" motor for a 2500-6500 rpm street shootout- would be too much head. but I get your drift...this is small potatoes compared to what he's accustomed to... Last edited by theoldone; 10-08-2005 at 09:17 AM. |

The SB2 SBC head that NASCAR uses flows 40 cfm and they put them on 350 chevy's.
Those 672 plus BBC's have 520/540 cfm heads. |

I read on Classical Pontiac that he did not hurt it at all. He went too far in the tune. At the last minute he decided to go to larger air bleeds and he leaned it out too far. He would have had second if he'd left it alone, but he didn't go there to win second, so he pushed it.

By my math, 4.310 bore and 4.375 stroke is 510 inches.
4.31" bore and 4.5" stroke is a 525" engine. Tom V.

Has he found them yet?
Note to self: When buying a crate motor, stick to Pontiac builders like Ken Keefer. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
