Why , I have never dynoed a engine/car in my life nor have I ever said I have dynoed anything.
IMO they are kind of overrated and underrated at the same time. If you have a engine/combo that you spent big money on and are pushing HP. Trying something different, want to carb dialed in from the start and/or want the info for the perfect torque converter, pay the 800+$ and go through a whole weekend or more of labor and for me, pay the 2,000 knock yourself out. But for all the people who dyno a 350hp known combo wheezer you just paid 800$ to check for oil leaks. I think its ridiculous. Make a run in stand, set the timing and check for leaks, install in car. My 461, if the stars line up I might get it dynoed this spring but if I do not have the time I will put it in the car and go racing. Everything in the combo is well thought out and should be very close to optimum. |

I did find a slip from the time I had unported 96s on the 455 for a few seasons. It was a 12.10 slip run with a cam that was too big for what I was doing. I just threw it together while I was waiting forever for Whitmore to finish my HOs for SR cam. When I find them I will put one up just for you Bill. It will go like 10.83, 1.44 60 foot, 119MPH, 6.92 in the 1/8. I do not throw stuff away that I probably should so they are still around. My 455 does not make make all that much power. Only reason it ETs good is I have a rear suspension like a 8-9 second car has and I race at sea level. I am just about in 3rd gear by the end of the 60 foot, let torque do the work. |

Yeah, the guy who suggested a 1000HP fire breathing beast of a cam with a little set of High Ports to go with a converter that was not matched to the whole mess.
It ran so well the customer bought a whole new set of canted valve heads, intake manifold, new roller rockers and valve covers, pistons, rings and re balance to get a decent time out of the 20+K he has to have in all of it. Like I said, experiences like that make a whole lot of former Pontiac guys who sell their Pontiac junk and call up Steve Schmidt and get a 800 HP BBC for 17K with a one years guarantee. Just glad he still has a Pontiac in it with whatever heads he wants. Kinda feel bad about what he had to have gone through. |

… .727/.676 is a fire breathing cam to you ?? 🤣🤣 … …the pistons were weight matched, but hey keep making more assumptions… … you’re throwing shade at a 9 second car and your car runs what ?? … 🤣🤣 … you couldn’t build a Pontiac that makes 1000hp if someone gave it you 🤣🤣 … … but yet DragnCar knows all, let us bow our heads at your intelligence sir 👍🏻 … … please continue 👍🏻 … |

How many hours have you had on a Dyno Cell, TTB?
Doubt if it is more than several hundred in your lifetime. Now you take a Pontiac Guy named Chris Piper (who worked for Ford Research in the dyno labs) who would run a engine dyno test program where his engines (6) (each one were on the cell for 2800 hours of testing). So Dragncar does not use a dyno cell. You do a few pulls on a dyno cell in a days time. Piper runs for 1000s of hours on a dyno cell for each engine of the 6 engines. I personally had a few years on dyno cells at Holley Carburetor, the 7 years on dyno cells at the Ford Motor Company doing Emissions work certified by the EPA. Last job in Ford Research (14 years) I had engines running on dynos for two shifts EVERY DAY for those 14 years. So everyone had a point in time with actual dyno cell experience. Think about that TTB when you make future posts about dyno cell testing, ................................ Tom V.

Even if that is a typeo and you meant 110 MPH or 109 MPH I still call BS. Now if the 119 MPH is your 1/4 mile number? That would be around 98 MPH @ 1/8 mile. Stan

Fwiw, 6.45 isn't 9s in 1/4.
Bill couple questions I'm curious about, since pistons where replaced did the ring pack stay the same as old? What rocker ratio he running with CV-1? |

Stan, not sure I agree with you numbers, we have ran 119mph with my brothers car and 1/8 was 95-96

Lol..... I'd imagine with guys as smart as Kevin Sweeny and TTB involved the ring pack was changed ( 8HP there) , seasoned cylinders re-honed with a torque plate ( 12 HP there) , correct cam timing (4HP) , improve rocker arm system (8 HP) and now we know where that 30 horsepower gain came from..... I mean those ex-employees from Sonny's and Kevin Sweeney don't screw around when it comes to making big power! |

Merry Christmas Stan, how much flywheel horsepower is this car showing? Also how much (if any ) of a power gain do you come up with? Last edited by PAUL K; 12-25-2022 at 10:26 AM. |
