B & M – B & M Torque Converter, Tork Master 2400, 50441 (Part No.50441)

B & M Torque Converter, Tork Master 2400, 50441

from

$549.99
This B&M Tork Master 2400 fits 1970-82 Ford C4 transmissions with a 1.375-inch crank pilot, 26 spline input and has a 10.5-inch bolt circle. Don’t let the exceptional value fool you into thinking Tork Master Converters are not packed with lots of quality features, making them the best value-priced street performance converters money can buy. These converters perform best when paired with stock to modified engines up to 350hp/350 ft lbs of torque, and lighter weight applications, like street rods. The Tork Master will provide noticeably quicker launches and harder acceleration while maintaining normal daily driving qualities. Upgrades like a new precision alloy steel pump drive tube, needle thrust bearing when factory equipped, new thrust washer between turbine and cover when required, and pressure tested and fully balanced by expertly trained technicians. Notes: Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. Not recommended for big block, supercharged, plate-type nitrous oxide or trans-brake applications. The product images shown are for illustration purposes only and may not be an exact representation of the product.

B & M – B & M Torque Converter, Holeshot 2400, 40422 (Part No.40422)

from

$662.99
This B&M HoleShot 2400 fits 1971-91 Ford, Lincoln and Mercury C6 transmissions with a 1.375-inch crank pilot and has a 11.4-inch bolt circle. The Holeshot converters are an excellent choice for vehicles with 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. Holeshot converters feature furnace brazed impeller fins and turbine, new precision alloy impeller hub and new heavy duty needle bearings. Other features include fully balanced and pressure tested by expert technicians. If your vehicle is equipped with a plate type nitrous system or supercharger, please refer to the Nitrous Holeshot line of converters. Notes: 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. Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. This converter is Not recommended for supercharged, plate-type nitrous oxide or trans-brake applications. The product images shown are for illustration purposes only and may not be an exact representation of the product. Note: For Small block engines only.

Edelbrock – Edelbrock Performer-Link Adjustable True-Roller Timing Chain Set, 7821 (Part No.7821)

Edelbrock Performer-Link Adjustable True-Roller Timing Chain Set, 7821

from

$86.99
Edelbrock part No: 7821 Performer-Link timing chain is for use with Edelbrock or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. Cam sprockets are made from 35,000 psi tensile strength cast iron. Crank sprockets are made from billet SAE-1144 steel and induction heat treated. Four Performer-Link sets are stock replacement parts and 50-state legal (see listings in bold type). All other sets have three keyway setting points to ensure accurate timing selection for early or late-model vehicles. Performer-Link timing sets are not for use above 6500 rpm. Performer roller chain sets are engineered to operate up to 6500 rpm. Never hammer directly on chain or sprockets. You can crack the hardened links and pins and cause early failures. Use a sleeve for installations that require hammering, a brass drift punch may be used if you carefully alternate blows on either side of the sprocket to avoid cocking. Never stretch the chain with a screwdriver. Check for clearance between the timing chain and block and between the chain and front cover before reassembly. Be sure that both cam and crank sprockets are exactly in line with each other. Misalignment can cause chain to break.
