This will create up to 11:1 compression on pump gas.

Milling/Decking: Without modifying the intake manifold,В LS1В heads can be taken to 62cc chamber volume.

Porting: CNC-machined factory heads (LS1В or LS6) can flow over 320 cfm.

Both respond well to custom machine work: TheВ LS1В heads were good, but the LS6 heads were better. Drop-in dual pumps are a common upgrade.Д¬ustom tuning will be required to properly adjust the fuel and ignition systems.Д«ecause of the popularity of LS upgrades, chassis dyno tuning with the factory ECU is most common.

Fuel pumps: The factory pump becomes a limitation at 450 hp.

Upgrading to larger injectors is required if youвЂ™re planning more power.

Fuel injectors: The standard 28-pound injectors only support about 390 hp at 90-percent duty cycle.

вЂ¦ Upgrading the LS1 Fuel System and Tuning the Engine But, for engines turning 5,500+ rpm (minimum), or are subject to nitrous backfires, they begin to make more sense. Single-plane intakes donвЂ™t make as much torque or power as the tunnel rams.

If hood clearance isnвЂ™t an issue, tunnel rams produce big gains at 6,000+ rpm.

Aftermarket manifolds usually have a four-bolt flange. LS1В and LS6 throttle bodies were both 78mm and had a three-bolt mounting flange. The Corvettes came with electronic throttle control (drive-by-wire).

When changing intakes, take note of the throttle body and the number of bolt holes in the mounting flange.ДЇ-body cars and the 2004 GTO were cable-operated.

These are generally better for cars with stock gearing and a mild converter. Long-runner intakes make more power through the entire range. Aftermarket intakesВ can produce strong gains with a 90mm (LS2) throttle body.В Short-runner intakes are better from 5500 rpm and up. The throttle body diameters are identical.

If you have anВ LS1, upgrading to the LS6 intake is inexpensive and popular.

If youвЂ™re on the hunt for the best mods for your LS1 engine, youвЂ™re in the right place. The aluminum blocks are not as strong as the LS-based iron-block Vortec truck engines like the LQ4 and LQ9,В but both the LS1 and LS6 can be pushed to over 850 horsepower with upgraded internals. On a stock LS1 engine, the following upgrades can improve performance and fuel economy:ДЄ stock LS6-a Gen III 5.7L aluminum block V8, just like the LS1-has more power than a stockВ LS1, but both can make the same power with common upgrades.
