Going to dyno the truck
Anyone got some guesses on power? I have never dynoed anything before so I am excited. I just dont know how my tires are going to like spinning that fast.

Sorry no guess, but I am interested in seeing your results, those are some big shoes to turn! Nice Challenger. Thats a good running 360 you have, what are the specs? I Have a 69 Dart that I put a 340 in. What a fun car.

What kinda Swampers you running? I dynoed with fairly new SSR's (10 ply radials) with no problem.
The issue that I "almost" had was being too wide to fit on the rollers. I ran wheels with 4.5" of backspacing and 12.5" wide tires. You may wanna check with the facility.
In terms of numbers, I say a bunch! Have fun.

You may have some traction problems on the rollers with those tires.......strap the rear down hard and add some weight in the bed if you can!..............running a 14.40 ET with 40" swampers takes big time power dude!.........I would not be surprised to see 400+hp and an easy 1000 ft/lbs! ..........BTW, do you know the weight of the truck?

If you still have the stock wheels and tires, you might want to consider using them for the dyno runs. This should eliminate the roller width problems and (assuming you'll be running on an inertial-type dyno such as the Dynojet 246C) give you a better indication of what the engine is actually producing in terms of BHP and torque. The inertia of the heavy tires and wheels will produce lower dyno readings than the stock-sized tires and wheels on an inertial dyno since the engine will have to overcome the inertia of the tires and wheels before it can attack the inertia of the dyno rollers.
Just a suggestion.....

Well I have bad news and good news. I got to dyno the truck but we couldnt pick up an rpm signal due to something not working(not sure). I am going back to do it again when my buddy gets it fixed. Truck pulled 368hp and dont know the torque yet. I did this in o/d with the converter locked up. Now I am talking to my friends and they are saying I should have done in drive with the converter locked up. What do you guys think? I am going back probably in a couple of weeks.
