No matter how outrageous, LSM has the ability to turn your idea into
reality; with the same care in design and engineering as our other blocks.
Here are some of the custom blocks we have made in the past. Available
as one-offs, or in volume, if you can dream it we can make it.
B Series Cummins

Manufactured from heat treated 4140 billet steel. This block has full
water jackets and is intended for diesel tractor pulling application.
Features cross bolted billet steel main caps. All standard Cummins parts
bolt right up. Block was featured in Race Engine Technology magazine.
This block is literally bullet proof.
Chevy ZR1 Corvette

This endurance series block also has full water jackets.
Integrated a standard GM bell housing so it can bolt up to
most popular GM transmissions. Accepts a standard SBC
crankshaft. Oiling changed to priority main. SBC motor
mounts. Cross bolted main caps instead of two piece split
crankcase. Accepts ZR1 heads and timing components.
Can be driven on the street or road raced.
Chevy Inline 6 "IGOR"

Designed to reduce block flex over the cast after-
market block. Integrated Jesel timing cover into the
block. Accepts large 60mm cam bearings. This block
just set a new record in NHRA Comp Eliminator.
International Harvester

Outrageous block used in pulling, hence the lack of
any lightening. How much power do you want to
make? We can build a block to handle it.
We have made blocks from large V8s to small V-twins. Call LSM about a Custom block today
