Product Details

The B&M Holeshot 3600 Torque Converter is engineered to deliver maximum performance for street and strip applications with GM TH400 (1965-1991) and TH350 (1968-1981) transmissions. Featuring a 3600 RPM stall speed, this converter provides aggressive launch characteristics ideal for modified engines with aftermarket camshafts and higher compression ratios.

Key Features:

  • Race-proven technology and quality construction for reliable performance
  • Precision alloy steel impeller hub for enhanced strength and durability
  • Copper furnace brazed impeller and turbine for superior heat resistance
  • Precision balanced on certified equipment to eliminate vibration
  • Optimized for engines producing 425-550 horsepower
  • Direct bolt-in replacement for stock converters

The Holeshot 3600 series is designed for vehicles with modified engines that require a higher stall speed to reach the powerband more quickly. This torque converter significantly improves 60-foot times and overall acceleration while maintaining street drivability. Compatible with both small block and big block Chevrolet applications using TH350 or TH400 automatic transmissions.

Prices are among the lowest around. Had a change with my order. Customer support team was quick to respond to emails and make corrections. Will order from Autoplicity again.

Great price, good e-mail communication and fast shipping. Positive experience with Autoplicity so far.

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.

QUICK AND EASY

I bought this item for my fiance and he loves it! He was completely happy with the price we paid...

Autoplicity has made my parts search so much easier. With the best price gurantee, i can now make autoplicity my one-stop shop for all my parts needs.

Good site easy to search for and find parts. The lowest prices on almost every part I have been able to find for my truck.
