Description

B&M Nitrous Holeshot 3500 Torque Converter, 1965-91 GM TH400, TH425 - 20484Overview: B&M Nitrous HoleShot 3500 stall for GM 1965 91 TH400, TH425, TH375 and 1968 81 TH350, TH375B (not TH350C.) The Nitrous Holeshot 3500 stall converter are an excellent choice for vehicles with many engine modifications, particularly big cams that tend to reduce low end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration.

Overview:

B&M Nitrous HoleShot 3500 stall for GM 1965-91 TH400, TH425, TH375 and 1968-81 TH350, TH375B (not TH350C.) The Nitrous Holeshot 3500 stall converter are an excellent choice for vehicles with many engine modifications, particularly big cams that tend to reduce low end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Nitrous Holeshot converters feature furnace brazed impeller and turbine, new precision steel alloy pump drive tube, new heavy duty needle bearings between the stator and impeller (not a thrust washer) and needle bearings between the stator and turbine. Other features include dual pattern 10.75 and 11.50-inch bolt circle, a new turbine hub, new springs and rollers in the stator and anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower that a nitrous plate system delivers. Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. These are serious converters for serious performance street cars. To prevent contamination left from worn parts being circulated in your new components causing premature wear, we strongly recommend protecting your investment by adding a B&M transmission cooler with all new transmission installations. Listed converters are NOT to be used in trans-brake applications. Not for use in trans-brake applications.

Features:

  • Needle Bearing Between Stator and Turbine
  • Higher Stall Speed, Quicker Acceleration
  • Anti-balloon Plate for Added Strength
  • Furnace Brazed Impeller and Turbine
  • Fully Balanced and Pressure Tested
  • Steel Alloy Pump Drive Tube
  • B&M Quality & Durability

So nice I bought twice!
Size: H Desk Unfinished 3/4-in and 1/2-in, Size: H Desk Unfinished 3/4-in and 1/2-in
For starters, this is a great buy if it is exactly what you want. For me that was the case and it would have cost me a good $40 or more to replicate it at a big box store. With that said, if you are not planning on using all of the pieces and want a different configuration, this may not be the kit for you. All of the parts inside are just like if you bought it at a local home improvement store. All the pipes need to be cleaned and protected. I personally found that dish soap (dry off immediately after you clean a piece) was the easiest to clean everything and I finished it with some wax. The kit is sturdy and easily supports the weight of my butcher block tops. I inverted the kit as it is designed as I intend on adding a shelf and am planning on using the support brace to aid in holding that shelf up for cable management. After cleaning and protecting, putting the kit together only took 5-10 minutes and that was with kid disruptions. I purchased 2 so that my wife and I could have matching desks in the office and I couldn't be happier.

Durable and sturdy. I bought two
Size: H Desk Unfinished 3/4-in and 1/2-in
Love the kit. I ordered two to make an L-shaped desk for my home office. Perfect height, looks cool, and sturdy. Slightly tricky to get two of them to the exact same height but you can adjust them buy loosing/tightning parts. Way cheaper than going to the hardware store and buying the same parts. I wiped each piece down as they are a bit dirty/greasy, but no big deal.

Great legs - sturdy when fully assembled with tabletop.
Size: H Desk Unfinished 3/4-in and 1/2-in
These legs are great. I put it together with a butcher block tabletop and it turned out beautifully. I recommend using a level on the legs once you get them into position and again when you place a top on it. The screws included were so easy to screw into the block but that will vary depending on the top you select. Watch the videos another reviewer posted on cleaning the legs with a mild soapy water and dry them thoroughly. It really helped me. Also after it was all assembled I used a clear acrylic - in a spray can to clear coat and seal the legs. I am really happy with it.

Exactly what I ordered, took just a few minutes to assemble and mount the legs. Love that the bottoms can be manipulated to give a balanced stance.
