The Mach 4 Air Straightener for 4500 series intake manifolds is 1" tall. If you are mounting your SV1 on a 4500 series intake, the Mach 4 is just the ticket for maximizing power and throttle response. The Mach 4 is designed for the 115mm blade equipped SV1 to increase horsepower, improve low speed signal on low signal engine programs, increase throttle response and drastically improve part throttle signal generation. A typical 900-1300 h.p. engine will consistently show a 7-12 h.p. gain when employing the Mach 4 Air Straightener.
Part # P26156 Fuel Lines, designed for Holley dual feed carburetors, feature braided -8AN line with a -4AN fitting for a fuel pressure gauge. Fuel line is 9-5/16” center to center.- Out of stock
Part # P7762 The Mach 3 Air Straightener for 4500 series intake manifolds is only 1/2" high to increase hood clearance (versus the 1" tall Mach 4 spacer). If you are mounting your SV1 on a 4500 series intake and even a Dual carb intake, the Mach 3 is just the ticket for maximizing power and throttle response without increasing your plenum volume OR decreasing hood clearance. The Mach 3 is designed for the 115mm blade equipped SV1 to increase horsepower, improve low speed signal on low signal engine programs, increase throttle response and drastically improve part throttle signal generation. Dyno testing on many 900 to 1300 h.p. engines has consistently shown us an average 10 h.p. gain when employing the Mach 3 Air Straightener. 
Part # PG-803 The PG-803 is nothing new. Its a professionally modified Holley regulator that's been used for years in NHRA Pro-Stock competition. Unlike look-alike regulators that make big flow claims yet still utilize the small seat area that froths and foams up the fuel. We install a 50 percent larger seat area to reduce fuel bowl foam and stabilize the fuel pressure during high flow rates. You get good clear burnable fuel and more consistent power from run to run. Once again simplistic design is the key to consistency and reliability. The PG-803 has enough flow capability to CLEANLY feed over 1000 horsepower!- Part # P26158 Fuel Lines, designed for Holley Dominator and SV1 series carburetors, feature braided -8AN inlet and -4AN fitting for a fuel pressure gauge.
Part # P7765 The Mach 2 Phenolic Shear plate for 4500 series intake manifolds is 1/2" tall. If you are mounting your SV1 on a 4500 series intake or Dual carb intake, the Mach 2 is just the ticket for maximizing power and throttle response. The Mach 2 is designed for the 110mm blade equipped SV1 to increase horsepower, improve low speed signal on low signal engine programs, increase throttle response and drastically improve part throttle signal generation. PLUS its phenolic so it acts as a heat insulator as well. A typical 700-900 h.p. engine will consistently show a 7-12 h.p. gain when employing the Mach 2 Shear plate.
Part # SPK1 Stop guessing! This is the best scope available for reading spark plugs. We're racers, so we even upgrade this one to have a super white light to make locating porcelain heat, timing marks and misting even easier. You say you don't know how to read all the information a spark plug provides? Well, you will now. Our tuning video is included. This video gives you an intense series of lessons in reading spark plugs and tuning your engine. You will watch this video over and over. Now you have the knowledge and the equipment...go tune that engine! Check out this link regarding reading spark plugs.
Fuel is what makes the power in a nitrous application. You have to get it there and you have to control it. This modified Holley regulator is setup to open on a hair trigger and offer stable fuel pressure throughout the run. It's been body relieved to speed up the opening rate and hand seated to reduce fuel creep. More instantly available torque for your nitrous program can be yours for only $64.95. Part # PN-803
