NOTICE

Please read this notice and only continue if you are willing to abide by our updated backorder acquisition and fulfillment terms of service.


Supply-chain disruptions have hampered our ability to acquire/restock items reliably. Additionally, a lack of backorder ETA information is a frustrating "new normal" for our hobby. As a result, we have had to change our BACKORDER ACQUISITION TERMS OF SERVICE. We are now only fulfilling order requests for items that are able to be acquired within 3 weeks IF we are able to get them. Longer than 3 weeks backorders WILL BE AUTOMATICALLY CANCELLED. Made-to-order, Special-Order, and Direct-shipped items may take longer than 30 days, and will NOT be auto-canceled, and will be fulfilled in the longer, as-advertised timeframe.


On the next page, you will be prompted to select a BACKORDER HANDLING INSTRUCTION for your Order Request. In every case, you are NOT CHARGED for out-of-stock items (we ONLY charge for items that are available to be shipped in a timely or reasonably reliable timeframe). If you select the "3 week backorder fulfillment option", you can email to cancel un-shipped/un-paid items at any time as long as they are not direct-shipped, special order or made/machined-to-order.

Currently our response time to emails is slow (we are severely short-staffed). Please trust that even when we can't reply to your email promptly, we are continuing to work to fulfill your Order Request as best we can, and we will contact you once we have any new information that is not already posted in your online Order Progress/History area in your customer account.


Please only continue if you are prepared to be PATIENT. Some of the items in your cart might be out-of-stock, and if that is the case, within a day or two we will post itemized stock status information to your account and/or email you to let you know. We appreciate your continued support and understanding.

4340 Forged Chromoly Super Race Type 1 Crankshaft, 76mm Stroke, Type 1 Rod Journals, 003-4376VW


 
4340 Forged Chromoly Super Race Type 1 Crankshaft, 76mm Stroke, Type 1 Rod Journals, 003-4376VW is a fantastic medium stroker crankshaft for budget builders. Made from 4340 Forged Chromoly, You'd need well over 250hp to out-do this crankshaft! Made from 4340 Forged Chromoly, this will rev as fast as your connecting rods and pistons will allow! 4340 Cranks are a step above cast and 4140 chromoly, and are great for applications around and over 200hp! The 76mm stroke is an excellent choice for all engines with the "mid stroker" build. This crank works best when used with 5.5" Rods, and "B" Piston and Cylinder Sets. This is a new crankshaft, so both Main and Rod Journals are STANDARD.

Case Clearancing for a 78mm crankshaft is not a big deal, the bigger the bore the less clearancing you'll have! If you have a small bore, you may have some clearancing for the rod nuts, at the cylinder spigots, and a little bit at the roof of the case also.

Another method is a rod length change. The logic behind this combo is as follows. "B" Pistons are designed for 5.4" rods. Since you are using a 78mm crankshaft, that's a 4mm smaller stroke (1/2 at the top, and 1/2 at the bottom). 2mm = .080" lower piston at TDC. We use .100" LONGER rods to put the piston .020" higher than stock, very easy to shim for, and you may not need shims at all!

Be sure to check piston skirt to Crankshaft CW Clearance during assembly, but this is usually not a problem due to the 5.5" rods!

These cranks are a GREAT way to build an engine with more grunt ON A BUDGET!!!
