How much can you bore a LS1 block?
Therefore, 19971998 LS1 5.7L aluminum blocks can only be safely honed (not even bored!) just 0.004-inch over the stock bore diameter. Improved liner positioning in 1999-and later 5.7L LS1 blocks and all LS6 blocks permit boring up to 0.010-inch oversize.
How much can you bore a LS engine?
Most factory iron LS blocks can safely handle a . 030-inch overbore, and the sleeves in stock aluminum blocks can typically be bored . 010 inch without a hitch.
Can you bore and stroke an LS1?
One of the easiest and most affordable stroker LS engine combos you can build is a simple 383 that combines a 3.905- inch bore and a 4.000-inch stroke. This can be achieved with either a 5.7L LS1 block or a 5.3L iron unit.
Can you sleeve a LS1 block?
In regular-production aluminum LS1 engines, it’s the cast iron cylinder liners that take the brunt of the abuse. It’s accomplished primarily by installing the Superdeck I system, which includes aluminum trusses to strengthen the block and ductile iron sleeves to withstand the combustion pressure.
Can you bore LS7?
By cutting the stroke and retaining the LS7’s 4.125-inch bores, it becomes an oversquare engine, with a 1.14:1 bore/stroke ratio (the stock LS7 is essentially square, with a 1.03:1 ratio) and an effective rpm limit of 8,000 rpm.
How big can you bore a 6.2 LS?
LS Engine Bore & Stroke Chart
| Engine Size | Bore | Stroke |
|---|---|---|
| 5.7L (346 c.i.d.) | 3.898 in. | 3.622 in. |
| 6.0L (364 c.i.d.) | 4.000 in. | 3.622 in. |

How much can you bore a 6.2 LS?
The cylinders can be bored to 4.080 in. However, we recommended leaving them as thick as possible when running boost. When bored and stroked, displacement can be as high as 427 c.i.d. (7.0 L). The block can handle 850 to 1000 horsepower.
What is the strongest LS block?
BMP claims its cast-aluminum (357-T6) LS block is, “the absolute strongest available with important improvements that even the factory race blocks don’t have.” The oiling system is priority-main, meaning that oil gets fed to the crank first and the top end last to prevent starving the main bearings of oil.
How much is it to sleeve a block?
A standard production small-block Corvette driver in average condition isn’t going to be worth the expense of a sleeving, which can cost upwards of $200 per cylinder depending upon location.
How much HP can a LS1 handle?
Even in emissions-legal trim, a blown LS1 will pump out over 500 wheel horsepower, with 800 wheel hp available for a serious stroker effort. With turbo motors, the sky is the limit, as 1,000 hp is a common occurrence, with the ability to adjust the power output by turning a simple boost knob.
How much horsepower can a LS1 block handle?
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.
