18 18 18 HOLLEY'S 105MM LS Throttle Body Holley's Dominator 105mm throttle body has a host of unique features including what is referred to as the "TPS CLOCKER". This patent pending design allows the TPS to be rotated back into the ECU's required idle voltage range. Modified LS engines no longer suffer from problems related to improper TPS voltage. Additionally, the throttle body's idle bleed allows adjustment without affecting throttle position or TPS voltages at idle. No more plugging to block off PCV valves. The throttle body also has an oversized bore that's larger to many other LS throttle bodies on the market. The throttle body also features a tapered transition, to help eliminate low RPM drivability issues when in the pits or off-idle. Holley's throttle body features a fully billet machined main body that is black anodized for superior corrosion resistance, perfect for the harsh off-road environment.

And while there are a plethora of head designs for the LS-Based power plant, the new RHS® Pro Elite™ 307cc Big Port CNC-Ported Cylinder Heads were made for bigger engines that require additional runner volume and air flow to support large cubic inches. The Pro Elite™ are the only raised runner aftermarket LS cylinder heads with the runner volume to support large cubic inch applications, yet are still able voltage range. Modified LS engines no longer suffer from 105MM LS Throttle Body voltage range. Modified LS engines no longer suffer from 17 17 to utilize both production and aftermarket intake manifolds and valve trains. Intake ports are raised .220-inch from the stock location for a straight line of sight into the cylinder. The heads also feature a .750-inch thick deck surface and reinforced rocker rails, which make them perfect for high horsepower and boosted applications. They work well with all existing LS parts, but have bigger intake ports and valves than the standard RHS® Pro Elite™ heads. They feature the popular 6-bolt head design, making them compatible with the RHS® LS Race Block, GM LSX Block and OEM GM LS blocks. These aluminum, CNC-ported heads feature a 307cc intake runner, 98cc exhaust runner and 69cc chamber volume. The intake valve is 2.250- inch x 5/16-inch, while the exhaust valve is 1.615-inch x 8mm. RHS® Pro Elite™ 307cc Big Port LS7 CNC- Ported Cylinder Heads are designed for larger cubic inch, all-out race engines, but are also ideal for 454- 502c.i. LS street engines.
