A stock LS6 does have more power than a stock LS1. However, they can both make the same power with common upgrades. The aluminum blocks are not as strong as the iron block LQ4 and LQ9. But, they can be pushed to over 850 hp. with upgraded internals. Below are some upgrades that improve the performance of the LS1 and LS6 engines. Engine Block

The engine specs and information here is for the stock LS1 engine. Mechanically similar, GM’s LS and LS-based Vortec engines wound up on almost every branch of the GM family tree: Chevy, Pontiac, GMC, Cadillac, Buick—heck, even Saab, Hummer, and Isuzu got some LS love.

A stock LS6—a Gen III 5.7L aluminum block V8, just like the LS1—has more power than a stock LS1, but both can make the same power with common upgrades. This will create up to 11:1 compression on pump gas. However, be aware that piston-to-valve clearance will be reduced.

Slideshow: From its super impressive engine to nifty new modes and features, the C8 has a lot to offer, especially for a car that is so well priced. We test a number of stock LS heads and came out with some very surprising horsepower numbers that will turn the Internet speculators on their head. valve 5.3L heads, the 241 (LS1), 317 (6.0L The 5.7L LS6 is the most powerful Gen. 3 small block engine as it came from the factory. It is an improved version of the LS1 produced for the 2001 Z06 Corvette. The LS6 powered the 2001-04 Corvette Z06 and the 2004-05 Cadillac CTS-V. The 64cc chambers will increase the compression on a stock LS1 from 10-1 to 10.5-1. The 59cc chambers will increase the compression on a stock LS1 from 10-1 to 11-1. Based on other modifications, gains of up to 40 rwhp can be expected. These are a great choice for naturally aspirated engines and applications where 75-150hp nitrous systems will be used. Look at all the people with turbos on stock LT1's and LS1's or any of the turbo honda guys, for that matter, who are running a stock motor. A lot of those motors are 10+:1 compression. A lot of those motors are 10+:1 compression. No longer will 241 applications be forced to trade compression for piston to valve clearance. Our HCR 241 will generate 11:1 compression on a stock 346cid LS1 while retaining the stock available P2V which allows the use of large duration cams without cutting piston reliefs! Static compression ratios into the 12.X:1 range are possible

22 Dec 2017 We test a number of stock LS heads and came out with some very terms of cylinder heads, we included the 706 small-valve 5.3L heads, the 241 (LS1), chambers, which meant a drop in compression of roughly 0.70 points.

Before selecting a piston, the desired compression height must be known. As shown, compression height is the distance between the centerline of the pin bore and the top of the piston. To determine the compression, three things about the engine must first be known: block height, connecting rod length and crankshaft stroke length. ls1 When introduced in the 1997 Corvette the LS1 was rated at 345 hp (257 kW) at 5,600 rpm and 350 lb⋅ft (475 N⋅m) at 4,400 rpm. After improvements to the intake and exhaust manifolds in 2001 the rating improved to 350 hp (261 kW) and 365 lb⋅ft (495 N⋅m). [2]

This is a discussion on Compression test question? within the Internal Engine forums, part of the LSx Technical Help Section category; So I just finished a compression test on my ls1.

Judging by head flow alone, stock LS6 heads could potentially produce about 5 percent more power than stock LS1 heads, and maybe a bit more because of the smaller combustion chamber's bump in compression. The LS6's hollow valve stems give the heads a bit more high rpm potential, and the sodium-filled valves can stand up a bit better in
