from

$54.99
Edelbrock part No: 7215 Intake Gaskets for 1958-1986 E-Tec 200 Small-Block Chevy allow for optimum flow and performance. Any gasket can create a seal, but a good gasket can do it with less clamping force, and for a longer period of time. The new MP-2N Micropore technology does not use solvents making our gaskets environmentally friendly. Impervious to most chemicals, this synthetic fiber composite provides a high recovery under load. This means that when compressed, the gasket will conform to any imperfections on the sealing surface even using lower flange pressures. A nitrile bead around each port opening makes the seal even better.

Competition Cams Valve Seals, 503-16

from

$223.99
COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

B & M – B & M Holeshot 3000, 20413 (Part No.20413)

$921.99
This Holeshot 3000 fits 1965-91 GM TH400, 425, 375 and 1968-81 TH350, 375B (not 350C). Holeshot torque converters are for serious-minded performance enthusiasts and offer additional strength and durability features not found in our Tork Master or Traveler series of converters. The Holeshot 3000 converter is an excellent choice for vehicles with some performance 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. Has both 10.75 and 11.50-inch bolt circles.
