LSx LONG BLOCKS

The Satisfaction of a Rebuild but With New Engine Benefits

Your car deserves more horsepower. You’d like better reliability (more hours driving and less time in the shop). You don’t mind getting your hands dirty, but you lack the time or resources to rebuild that tired old lump. If that sounds like you, consider an LSx long block .

Just the Basics

A new LS1, LS7 or LS3 long block comes complete with heads but minus intake, exhaust and auxiliaries. Swap them from your old engine or buy new with the appearance and characteristics you’ve always wanted. Going the long block route, it’s feasible to pull into the garage Friday evening and drive out Sunday night with a new engine purring under the hood!

A Small Block to Suit Your Car and Your Needs

If it’s the basic 350ci you’re after, a Gen III LS1 long block should do the trick. Alternatively, an LS7 long block gives you Gen IV features and 427ci of displacement. Splitting the difference between LS1 and LS7, the stronger block casting of the 416ci LS3 long block is engineered to handle all the power you want.

What Does a Long Block Include?

A long block includes a short block plus a camshaft and fully built cylinder heads. Breaking that down, a Golen Engine short block LSx comprises a new GM block and crank, along with forged steel rods and Speed Pro or Mahle pistons. Every component we use, from bearings to rings to camshaft, is American-made.

Blueprinting is part of the service. That means we work within the original GM tolerances to optimize both power and reliability. Then, the whole assembly is balanced to minimize vibration and maximize bearing life.
