VICTOR JR. LS1
CARBURETED OR COMPETITION EFI FOR GM GEN III (3500-7500 rpm)
This high-rise single plane intake is capable of supporting up to 600 hp. The Victor Jr. LS1 accepts a square bore carburetor and includes an electronic timing module that picks up MAP, crank position, and cam position in order to drive the stock LS1 Coil-on-Plug ignition system. The module offers a choice of several built-in timing curves, each tailored for engine displacement, cam profiles, and fuel grades. The #29087 (manifold only) can be used on LS2 applications when matched with MSD's #6012 LS2 ignition controller (available through MSD Performance).Includes a throttle bracket designed to work with 700R-4, 200R-4 and Turbo 350 transmissions. Most applications will require hood modification.
Applications Part #
Victor Jr. LS1 Carbureted Intake Manifold with Timing Control Module #2908

Installation Notes: Uses LS1/LS6 style individual port o-ring seals. Crankshaft sleeve #HP3795 and Flexplate #HP4004 is recommended when using a TH350, TH400 or 700R4 on a LS1; these items are available through Hughes Performance retailers or you can call Hughes at 800-274-RACE. Victor Jr. LS1 EFI also available with electronic fuel injector bosses. Manifold height: A-4.95", B-4.95", see A/B Measurements. see manifold reference dimensions. Port exit dimensions: 0.98" x 2.74".

Note (A): LS1 Timing Control Module #91238 works on LS1 24x reluctor wheel (crank trigger) applications only; LS2 applications with 58x reluctor (crank trigger) requires MSD #6012 ignition controller. Please contact MSD tech for details (915) 855-7123. LS1 (24x) applications can be recognized by the rear mounted cam position sensor (black in color), while LS2 (58x) cam sensor is mounted in the timing cover and is gray in color.

 

SUPER VICTOR LS1
CARBURETED OR COMPETITION EFI FOR GM GEN III (3500-8000 rpm)
Building on the success of the Victor Jr. LS1 manifold, the Super Victor LS1 offers greater air flow potential for ever bigger power gains from these modern engines. The carb mount pad is 1.12" taller than the Victor Jr. LS1, and the port exits have been increased to 1.08" x 2.74". Use Edelbrock Timing Control Module #91238 to drive the stock coil-on-plug ignition system. This manifold has already been accepted by NASCAR for use in the Grand National division/Busch North spec engine series. Super Victor EFI LS1 manifold #28095 is for high-output competition EFI systems and features precisely positioned and machined injector bosses for excellent fuel spray patterns and maximum power. Universal 4-Barrel Throttle Bodies, fuel rails, fuel injectors, fuel pumps and regulators are available separately to complete your competition EFI system.

Note (A): LS1 Timing Control Module #91238 works on LS1 24x reluctor wheel (crank trigger) applications only; LS2 applications with 58x reluctor (crank trigger) requires MSD #6012 ignition controller. Please contact MSD tech for details (915) 855-7123. LS1 (24x) applications can be recognized by the rear mounted cam position sensor (black in color), while LS2 (58x) cam sensor is mounted in the timing cover and is gray in color.

 

VICTOR JR. L76/L92/LS3
FOR LS Series GEN IV ENGINES WITH L92 HEADS (3500-8000 rpm)
Designed for Gen IV LS engines equipped with L92 cylinder heads, this manifold is intended for EFI racing applications operating between 3,500 - 7,500 rpm. This manifold uses a standard square-bore carb flange that is compatible with both Edelbrock EFI intake elbows and throttle body or four-barrel throttle bodies. L92 heads are only compatible with a 4.00" and larger bore diameters; smaller bores (including most 5.7L blocks) will require valve reliefs cut into the block. Available for carbureted and EFI applications; EFI manifold #28455 has additional bosses and machining that allow for the use of fuel injectors when combined with the #3638 fuel rail kit. Also comes with bolt kit.
Applications Part #
Victor Jr. LS Series Gen IV Carbureted Manifold for L92 heads #28457
Victor Jr. LS Series Gen IV EFI Manifold for L92 heads #28455
Victor Jr. LS1 EFI Fuel Rail Kit (Standard injectors with stands) #3638
 
Throttle Body Recommendations: Edelbrock #38783 or #339783.

Installation Notes: Uses LS1/LS6 style individual port o-ring seals GM PN12590125, L92 heads are intended for 4.00" bores and will not work with 5.7L blocks without valve reliefs. Manifold height: R-1.85", F-0.57", H-2.42", CH-7.40", CA-0°. See manifold reference dimensions. Carb height (CH) for this manifold is measured from the valley cover flange to the carb pad.

 

LS1/LS6 Valley Plate
This as cast aluminum plate is intended for use on 1997-2004 GM LS1/LS6 engines and similar GM Gen III engines that have been converted from EFI to carbureted set ups. The plate includes a breather boss that will need to be drilled and tapped by those retaining the stock LS6 breather configuration or for LS1 users looking to convert to a LS6 style. Note: will not work with LS2, LS7, LSX or any other GM GEN IV engines.
