At LSX Performance Parts we have put together a range of the best priced, highest quality stroker kits available for LS engines, but which kit is the best value?

Our LSX Stroker Kits are packaged to suit each engine however the kits offer a very diverse range depending on brand, horsepower ratings etc.

In majority of scenarios our most popular kits are split into two very different applications which is either N/A (naturally aspirated) or boosted (targeting around 850hp for a streetcar). These kits are typically made up of similar Crankshafts & Conrods with the difference being the Pistons which will determine the compression ratio for the engine depending on the application.

In all of our kits we treat our "Entry Level" as items with a horsepower rating of 1,000hp. Although 1,000hp is hardly "Entry Level" this rating filters out the cheaper/sub-par quality kits that we would not use, nor would we recommend!
This means that our "Entry Level" features the most premium brands on the market which includes household names such as Callies, K1 Technologies, Manley & Lunati while our pistons are a range of Carillo from their CP Bullet Range which all feature a minimum 1,200hp rating!

Which Kit Offers Best Value For Money?

The best way to answer this is to break it down into categories.

Naturally Aspirated:
We find the best value for money combination when it comes to N/A engines is combining the following:

Crankshaft: K1 or Lunati Crankshafts
These both are manufactured from Forged 4340 Steel, featuring 6 counterweights & 1,000hp rating!
This will suit majority of N/A engine applications as they will handle high RPM & exceed the horsepower capabilities of majority of N/A Engines.
These two options are the most affordably priced with this HP rating!

Conrods: Callies Compstar or Manley H Beam Conrods
These are both considered two of the most underrated Conrod options on the market due to their understated horsepower rating & value for money.
Both options are manufactured from Forged 4340 Steel using a H Beam design & feature ARP 2000 series conrod bolts as a standard.

Pistons: Carillo CP Bullet Flat Top Pistons
For majority of N/A Pump fuel applications the Flat Top piston option is the way to go. This will provide the compression ratio that will suit Pump Fuel (98 or similar) and are available in a range of bore sizes depending on your block. 
These come as a standard forged from 2618 alloy & feature a specific CP Ring Pack, high quality wrist pins & locks. 
All CP Bullet pistons have valve reliefs which allows for much bigger lift camshafts without the Piston To Valve Clearance issues.
For higher compression applications such as ethanol or race fuel engines, we also offer a range of Dome Top Pistons!

Forced Induction/Boosted:
We find the best value for money combination when it comes to boosted engines targeting up to 1,000rwhp is combining the following:

Crankshaft: Callies CCW 8 Counterweight Crank
This crankshaft is possibly the best value for money crankshaft on the market in terms of dollar per HP capability.
This is a proven 1,500+hp capable crank due to its high quality Forged 4340 Steel material and the addition of the 8-counterweight design which makes it extremely rigid & capable!

Conrods: Callies Compstar or Wiseco Boostline
The Callies Compstar once again gets a mention for being as above. the most underrated Conrod option on the market due to their understated horsepower rating & value for money. Although they do not advertise it there is no shortage of 1,000+hp engines running these.
In the interest of over-engineering a nice step up from this conrod in terms of HP rating is the Wiseco Boostline.
These feature a unique A Beam design which makes them extremely rigid and capable of up to 1,800hp. Although these conrods are known to be quite heavy they definitely produce some serious numbers!

Pistons: Carillo CP Bullet Dish Top Pistons
In boosted applications there is a much wider range of selections for pistons depending on desired compression ratio.
This is usually based off the following among other factors:
Power Adder: either Turbo, Supercharged or Nitrous
Fuel Type: Pump Fuel, E85/ Flex Fuel or Race Fuel

As a general rule an engine on 98 will run slightly less compression than an ethanol fuel due to combustibility.
Also, an engine running a positive displacement supercharger will run slightly higher compression than a turbo engine depending on the sizes etc.
When selecting pistons our listings will provide a Comp Ratio depending on the cylinder head combustion chamber volume etc.
To simplify it, the bigger the dish, the lower the compression.

By following this guide, you will be able put together the combo in our range that best suits your planned horsepower and build.
