Frequently Asked Questions

What oil should I use in my new Hemi?

We recommend VP Racing Oil or the equivalent.  It is important that your choice of oil contains zinc or the addition of a zinc additive.  For viscosity, we recommend 15W-30 or 15W-40.  However, climate and other factors will help to determine viscosity.  Synthetic oils are adequate to use, but non-synthetic is preferred.

What should the lash gap be set to for my engine?

Valve lash should be set on a warm engine.  The lash setting will be listed on your cam card.

What Spark Plugs do you recommend for my new engine? 

We use NGK-R6061-9 spark plugs in our race applications and NGK-4644 in our street applications.

Do you have any pre-built engines?

No, all RBRE Engines are custom built to meet our customer's requirements and applications.

What is the starting price of your Hemi engines?

Generation II Hemi builds start at $35,000 USD.
