Induction

Holley

Shiny, ”polished looking”, version,vacuum secondary.
Features: Manual choke, power valve blowout protection. Prim jet 51, sec plate equiv to a 53 jet. Jetted for a standard 3500 Rover V8. Rejet for use with modified cam etc.

Edelbrock

Shiny, ”polished looking”, version. Basically a revamp of the the old Carter AFB carb from the 60’s. Should work well on 4.6litre and above. Features: Manual choke, prim jet .086, secondary .095, metering rods .065 x .052. jet. May need PP-BY8089 banjo union.

For use with a Holley carburetor and Offenhauser or Edelbrock manifold. The kit includes a cast aluminium bracket. Check to see if the accelerator pedal fitting is the ball type or the barrel type.

Edelbrock

Dual plane, low rise, aluminium inlet manifold with a 180o firing order. The runner design improves torque over a wide rpm range, especially off-idle through the mid-range. Throttle response is excellent. Up to 10bhp more than the AZ834 in the high mid range. Will not work with the standard carburetors.

The 360deg design of the manifold lets the engine operate at full capacity at all times. A 180deg manifold operates on a part time basis due to the fact that one side of the manifold is down while fuel is delivered to the other side of the engine. The Equal-flow plenum chamber wipes out flat spots in the rpm range, with each cylinder receiving equal fuel flow without interuption or oscillation.

This manifold is the lowest available, & widely used for conversions like the MGB V8. It requires a 4 hole spacer or wedge plate, as the manifold entry is the 4 hole type. The manifold has dual ports, where it meets the inlet port. Several benefits are claimed by using dual ports. The primaries use the lower port, and the gas speed is claimed to be higher than normal. The secondaries use the upper port, which being shielded by the primaries, will be cooler. Ultimately, greater power & less polution are claimed!

Use on the SD1 Borg Warner gearbox only. For use with the Holley carburetor and Offenhauser or Edelbrock manifolds. Kit includes cast aluminium brackets.

The Rover V8 engine originally sat in the car-tail down. Inlet manifolds were designed with a built in ”angle”, to keep the carburetor level. When the engine is mounted level, as in the Range Rover and most kit cars, it results in the carburetor being tilted. The simple solution to this problem is the use of a level plate to mount the Holley carburetor level.

ARP

Features a 12 point head, a generous flange for even loading, and washers to prevent galling and promote accurate torque readings. Rated at 170,000 psi tensile strength. Uses a 3/8” socket.
