My brother has been pulling with it since day one, it was his everything truck for years. About 15-20 years ago he started modifying it into a purpose built puller, first Super Stock now Pro Stock.

There are 7 serious pullers in his class in the Montana area, not to mention Idaho and Utah pullers. All are in the 1200+ hp range.

He ended up 2nd overall in Bridger. They pull twice and add the footage. He missed 1st by 1.2 inches. 3 Fords and 3 GM's competed. One Ford w/Jon Kaase built power and one GM both lost a rear end on the first pull. Must be contagious, now his rear is broke. Lost it in Havre Saturday. Now the stress is on to get a set of gears in time for the NHRDA pull in Billings this Saturday. They welcome the Gassers too.

You can't see the truck for the dust but you can hear it, what a beautiful sound! 1st place out of 5 trucks.

Since I didn't pull this year I will share my brothers truck. He has been pulling this truck for 35+ years with a 400m, in one configuration or another, from box stock to Pro-Stock. He lost #7 rod on the first pull of the season this year so he missed most of the pulls. His current engine is 434 with CHI top end, about 600 hp. Keep in mind this class allows 565 cid. 1000+ hp engines. I think we can all relate to being the underdog at some time or another in our quest for fun in motorsports.

This video is in Bozeman, Montana 08/26/17. He pulled to a 4th place finish with a field of 9 trucks, the 10th truck broke down unloading it. If anyone is interested after clicking on the link, click on the uploads of the poster and you can see all 9 videos of his class.

He wants to get back up to the top of his class so he has ordered a 565 from a vendor on this site.

I have always had cheap BB guns, with the current one an old Crossman 66 Powermaster pump up.

 I just bought a Ruger Impact 22 cal. break barrel with 4x32 scope. It appears to be an amazing rifle with wood stock and even a Picatinny Rail mount and weighs 7 pounds

 I was just wondering if anyone else has a pellet rifle that can share info, so I don't have so much trial and error work to do, lol

 I think now I need a companion hand gun in a CO2 powered. In the old days, the guns were not sealed very well and every time you wanted to use it the canister would be empty. Has that improved at all?

Like the topic says, is there a generic rule about this with any given engine build? I know there are a lot of factors that influence ignition timing, but once a build is established, with all the factors of that build including gas octane.

On my Ford puller I have the total timing set at 37* and never change it. Should I be? My normal pulling elevation averages 4500 feet. Am I leaving power on the table if pull at 2000 feet or 6000 without an adjustment.

I noticed at the Powell, Wyo. pull (4500') that all the west coast trucks got beat by the locals. These are good tough pro mod trucks, but they pull about 500' average. Did the elevation beat them?

If there is only 10-15 hp lost that's probably not enough to matter, but if there is 25-30 lost, that does. Is that much possible or no?

Here is a dyno sheet of my Cummins powered '01 Dodge 2500 and why I tow with diesel power. Towing my sled puller on my 20' equipment trailer I gross 17k lbs and get 12 MPG. Back in the day when I towed with my 428's they averaged 4 MPG in the slow lane It's crazy how much usable power you can make with only 360 cubes of turbo charged diesel power.

The curve was kind of goofy but I think that was because they started the run too high in the RPM band, they should have started about 1500 rpm. With the cruise set the 6% grades are leveled out but the rear tires seem to melt off

I have read a lot about this, that it is "easy" to get this number. I have also read a lot, that it is "easy" to get 2hp per CFM of head intake flow. However they don't seem to both add up the same. Since my 428/440 FE is on the mild side or in the "easy" category, I should have 440 hp. Or using the 2 hp head flow numbers, my ED's advertised at 270....I have read that in real life this number might be closer to 250..... so using the term "easy" I should have 500hp.

So....using my seat of the pants meter and a chassis dyno for power numbers, I would guess my 440 is more in the 400hp range. I have posted a dyno sheet that I have of this engine, before the Edelbrock top end kit and was  when a stock '08 Toyota Tundra beat my numbers, Lol. Any thoughts?

I am having a difficult time posting a normal sized picture. I keep getting "file is too large" so I down size but they are so small you can't hardly see them. I see some pictures on here that are full page size. Can anyone please help?

Thanks,

Nick
