Edelbrock Performer RPM cylinder heads for 455 c.i.d. Pontiac engines are now available with a CNC machined chamber.

Performer RPM CNC cylinder heads have the same specifications as Edelbrock's Performer RPM cylinder heads for 1962-79 455 c.i.d. Pontiac engines, but feature a revised CNC machined combustion chamber design with an all-new spark plug location for improved performance. Performer RPM CNC cylinder heads are available in two chamber sizes. The 87cc chamber version is ideal for 9.5:1 engines and will deliver excellent street performance on low octane fuel. Performer RPM CNC cylinder heads with 72cc chambers are best for higher compression engines. Both are patterned after the same port flange configuration as the 1969-1970 Ram Air IV Pontiac cylinder head.

Holley Performance Products has been developing a variety of parts to make a modern GM LS series engine swaps easier into classic and Muscle Cars. In this video, we take a look at the new Holley LS Accessory Drive Brackets and install them on the L92 V8 in our '66 GTO. These fit all the LS engines and are inexpensive as well as functional. Cool stuff.


Manual transmission swaps into Muscle Cars are extremely popular, and many companies make retro-fit kits allowing a late-model 5 or 6-speed manual to be installed in the factory position in older cars. However, just because a shifter fits the car does not mean it fits the driver! Twist Machine came up with their Billet Adjustable Shifter Handle that allows you to place the shifter in any of 7 positions, guaranteeing you'll find a neutral, comfortable spot to match your reach and driving habits. You remember how much you like your tilt steering column? This shifter will help in the same way. You will be a better driver because of it.



Edelbrock Air Cleaner

Edelbrock's Classic Series engine dress-up accessories deliver a definitive appeal that brings back a look from the 1950's.

Edelbrock first made these aluminum valve covers in the late '50s and they continue to be a classic. Made of heavy-gauge sand-cast aluminum, our classic finned valve covers are now available in a natural as-cast finish, for enthusiasts looking for a subtle classic look for their engine.

Edelbrock Classic Series air cleaners are available in three models; a single-quad 14" round, single-quad oval and a dual-quad oval to give plenty of options for any hot rod or muscle car. The small oval air cleaner provides adequate hood clearance in demanding applications as well as a coordinated appearance with the classic finned look. All of the air cleaners include a pre-oiled and washable cotton gauze element for excellent filtration. They are compatible with all popular 5-1/8" diameter carburetors and throttle bodies.
