Description

OEM REPLACEMENT

Our precision CNC machined, and Computer balanced 350 block

This 4-bolt main 1pc seal P/S dipstick block must pass our magnaflux inspection designed to detect any microscopic flaws or cracking. Blocks are then thermally cleaned, followed by steel microblasting until they achieve a brilliant appearance. Once a block is fully cleaned, we begin our precision boring and honing process. Using a carbon two-stage power hone, we can maximize the sealed area and ensure that it precisely meets the recommended RMA readings. Computerized micrometers are used to resize rods in strict accordance with factory recommendations. Crankshafts are precision cut and micro-polished to achieve a 12 RMA reading or better.

Custom 350 long block assembly

We meticulously mill each TBI Cast Iron (76cc, 1.50ex/1.94in) Cylinder Head until perfect alignment and sealing of the head gasket are achieved. Our cylinder heads are assembled using a new valve stem and seals that feature the latest in high-temperature technologies increasing heat resistance and longevity. These polished cylinder heads are pressure tested using magnetic detection to eliminate the chance of cracks or flaws unseen by the human eye. Before each head is mated to their block using the correct torque valve, we vacuum test all seals for proper seating. Triple-angled cutters are used to machine the valve seats, ensuring proper pressure and flow. All valves, valve springs, and valve guides must pass our stringent process of meeting and exceeding OEM specifications. O.H.C. heads are aligned for proper bore consistency. Every remanufactured long block has been specifically engineered to help improve the inherent flaws and failure points that can be found in many of today's engines.

Helping us give you the best prices available.

This part is sold at a price based on a rebuildable core being returned to us. The recycled metals and components can assist the manufacturing process keeping our prices to an all time low. This temporary deposit is withheld to ensure that we receive your damaged unit.

How is the core deposit charged?

How is the core deposit charged? At the time of purchase the core deposit will be added to the customers total. Once the core is received and processed at our facility, the deposit will then be issued back to the customer.

How long do I have to return my core?

To receive a full deposit your core must be received within 30 days after the delivery of your part. Late fees may be assessed to cores that are returned beyond 30 days from the customers original purchase date. Any extensions must be proved by a sales manager.

Refund Time?

Orders are typically refunded back onto the credit card within 1-3 weeks after the core arrives. Check orders will be mailed back. Call to verify arrival if you have not been refunded within your 3 week window.

How do I return the core?

In most situations your unit will be delivered with a shipping form called the “Bill of Lading”. You or your shop can send the core back with the delivery driver or at a later date by calling the shipping company to schedule a pickup. Be sure to use our shipping form or the shipping company may bill you personally. If your form has been lost or misplaced you will have to call our shipping department to generate a replacement.

Bad or missing core?

If there is no core to exchange, in most cases we can just add the deposit amount to the purchase price. In addition, you will only be required to pay a one way shipping fee. In the case that our stock becomes low on a certain core, we may charge an increased amount for the core when there is not one to exchange. In the rare case a core becomes critically low we reserve the right not to sell a product without a core exchange.

Can I send my core first?

You can send us your core before we send out your unit. By doing this overall shipping may take longer but you will not be required to pay a core deposit just shipping and the price of your part.
