SLP is putting together some low cost but high quality rotating assemblies that can be used with GM's LQ9 iron 6.0-liter block. 383 and 402 cubic inch displacements will be available. Here is a quick rundown of what they are producing and what we will have to offer -

ZL 383 - low compression -

4.000" 4340 forged steel crankshaft, balanced to rotating assembly
3.899" heavy-duty, high-compression 2618 forged alloy pistons (includes new rings and full-float pin)
6.125" I-beam rods
383-CID displacement
9:1 compression ratio (nominal; ultimate compression ratio will depend upon heads and gaskets used)
Designed for forced-induction applications
Includes new rod and crank main bearings


ZL 383 - high compression -

4.000" 4340 forged steel crankshaft, balanced to rotating assembly
3.899" 2618 forged alloy pistons (includes new rings and full-float pin)

383-CID displacement
10.8:1 compression ratio (nominal; ultimate compression ratio will depend upon heads and gaskets used)
Designed for naturally aspirated applications
Includes new rod and crank main bearings


ZL 402 - low compression -

Will they offer anything w/ a 3.905 piston? Are the rods forged?
