Cylinder Core Exchange Options(see drop-down menu):   

If it is peak season please call to verify we have cylinders in stock otherwise we will have to use your cylinders for boring and porting which extends lead time out 

• Option 1: Purchase Outright - No core cylinder or exhaust valves are required to be sent in - Raises kit price by $2000
• Option 2: Exchange Parts, MUST send your cylinder and exhaust valves within 14 business days. As soon as you do, the $2000 charge will be refunded. Exchange parts not received in that amount of time will have no credit applied, and the customer will have to pay for return shipping. 
• Option 3: Exchange Parts - Your order will be pulled on our shelf waiting for your exchange cylinder & exhaust valves to arrive. Once they arrive, we will normally ship the kit within a few business days. No core charge will be applied since we will have your cylinder prior to shipping the big-bore cylinder.
