mine has been run from 2002.after 3yrs i checked the bearings and caps[stock iron w/studs]there was signs of walk.the cheepest,least invasive improvement was a girdle from gearsandrears[chenoweth] so i have been using that and will check the bearings next yr 2010.i cant realy explain why,whynots.i just hope it last.
Can you give me a rundown of your build with cam specs included? I watched your video it looked like about 900hp @ around 6200. That would be perfect.

I'm guessing the carbs are dominators from the jet sizes you listed. Was I close on the HP and RPM? Can you list your dyno run? Thanks.

I've got a drag sim program and I wanted to put your car in and see what it should be running, can you give me the info on the converter stall and gearing, tire size? Thanks

Just from the Video it looks like a torque converter issue, the car seems to stay at 5000 for a little while before the revs climb, I'm not sure but this would indicate that you might not have enough gear or the engine is down on power.

cool,sure! convertor stalls at 5,000 off the line,TF 727 stock gearing,4.10 gears,28" tire 15psi.the car traps a 6500 rpm/131+mph.3% slip or close. the dyno #s are .08 correction% so you can subtract it from the HP/TQ.

Ok I ran it with the peak power figures from the dyno sheet, I set the weather conditions for an 80f day at 500feet elevation and barometer at 29.92. It says you should run a 9.53 @ 130 mph with 6% slippage. So the mph is right there but the et is off a bit. Thanks for the info, that is a super cool ride.

okay what is it you dont like about the girddle idea?
Just personal preference, but in my opinion, the girdle does not help, but actually hurts the situation. The main web in the block is the weak link, not the cap. Cap walk (cap bounce really) generally breaks the cap, beats the main web out of the block and then breaks the crank. You install a better cap, but it still bounces and breaks the block. The motor is always trying to throw the crank out the bottom. Just a natural thing that you can't stop. So a girdle ties it all together, but you still have the same forces in action, only now, they are all concentrated to the main web, which is the weak link to start with. Alum caps and rods, will absorb some of the shock and not transfer the brunt of it to the main webs. Some, many actually, will not agree, but this is the way I see it. I have heard the other side and I don't buy it. All I can go on is my own experiences. And that is, that I have built some pretty high HP, stock block motors, that had a ton of passes put on them. Never had one of those motors with alum caps and rods, break a block. These girdles for Mopars have been around for years, it is nothing new. I saw the first one in the 70s. My dad bought one for his Super Stock car in about 1974 and after inspection, it did not go on. The first one I actually saw on a motor, was one of Dvorak's stockers. They were kind of popular, then faded out. Koffel, also made them years ago. They seem to have a new following these days, but as I said, nothing new.
Monte
Oh yeah. The first set of alum caps I saw, was also in the 70s. My dad ran SS, but was also an engineer at a major industrial plant, plus he built all his own motors. He drew up a set and had the machine shop at the plant, whittle them out. My dad was pretty innovative. He petitioned NHRA to allow the manual carbs for Six Pack cars, and got it passed. He had the first roller bearing pinion support for a 9" Ford, that the Phlanx corporation ever made. He has the Weiand Six Pack Tunnel Ram, before Rossi had it.

JMO They might last for a while under or at 700 hp. The main girdle, and other stuff will not keep them from splitting the cylinders.
Good point. If somebody is buiding 600+ hp in a stock block, they should sonic check the cylinder wall thickness of several before choosing one. Many have scary thin spots, some are just "poor" production standards, and others are actually reasonably good. But you might need to check 10 to find a good one.
I did that, and went to aluminum main caps 3 years ago. So far so good.

9.53 @ 130mph? Damn, then I should be in the mid-low 9`s since I`ve been 132.90 in the 1/4 mile. Something don`t seem right....could you tell me where I can get that info/program? THANKXXXX...
The mph will vary depending on the converter/engine combo, the more efficient the converter, the higher the mph, alot of people also forget to subtract at least an inch from the tire diameter as well. The program I use is Drag race analyzer by performance trends. I use it in combimation with Engine Analyzer Pro, also from them.

Did 985RWHP on a short filled, aluminum capped and girdled destroked 440 turbo'd 388 cube. Mains looked like new after a year of beating on it.
Then I wised up bought a KB block and made more power on less boost with some more cubes.
