If you're looking to build the a high horsepower NA L-series engine, this is your kit. This kit includes:

A fully balanced 85mm stroke billet crankshaft with knifed edged counter weights.

89mm bore copper head gasket with an internal fire ring to ensure no combustion gases escape, unlike cheap multi-shim layer head gaskets which are known for leaking.

Chromoly H Beam rods.

ARP bolts for Head, Mains and Rods.

Custom Forged Pistons with coated skirts and performance rings. Unlike other vendors that offer you flat top pistons we offer you the chance to be different. Please tell us your cylinder head choice and compression ratio desired so we can create your custom piston. We recommend 88.5mm unless you have sonic tested your block and you know you can go safely to 89mm.

Performance ACL RACE Tri-metal bearings for both rod and mains.

Need machine shop services? contact us. We take engine building very seriously and we keep our bore tolerance to +-.0005" basically a perfect cylinder. 

Some parts are special order and take 6-8 weeks to make.
