First let me make it clear that the often-used term “harmonic balancer” is totally wrong. The next level up would be the Pro-Tru series that are much more expensive and made from 2618 aircraft alloy. They are usually made of the same 4340 material that steel rods are produced from for racing, but are lighter forgings and not machined all over. If the rod journal bores check out OK and the bolts are in perfect order, you have a set of the most basic rods for a hopped up motor. 5 STAR RATED BY CUSTOMERS, SINCE 1979: Ross is one of the most trusted names in forged pistons for Chevy 350 Small Block applications. At this point I am going to make the assumption you will be using a Scat rod. Indeed external balance mass puts additional loads on the front and rear main bearings. Free Shipping by Amazon. Although these narrow rings are more expensive by far than the 5/64 wide compression rings (which are really low cost) used on the piston on the left, the fact that you already have a good piston means only buying a set of medium-priced rings instead of a low-cost set of rings and a set of pistons. What you see here is a highly functional rod and piston assembly for a 600-hp build. Using the cost of a regrind as a yardstick, if you have to acquire a stock cast 350 core, your crank cost will double that of regrind on a core already owned. Also, if rods and pistons toward the lighter end of the scale are used, it balances internally, allowing you to use a stock 350 damper/ flywheel/flexplate. To put that into perspective: not only do you get a new and stronger crank, but also the torque increase per ft-lbs is about 40 percent of the cost, of that delivered by a typical bolt-on blower installation. Check the area for comparison indicated by the red arrow. These rods fall into the “sportsman” category. If you build to the book (this book, that is), you are unlikely to see less than 1.1 ft-lbs of torque per cube with 1.2 to 1.25 being more common. These rods are far better than any of the previous rods and do make a good choice for a rebuild up to about the 480-hp mark if you do not have the budget for a new set. Both run about the same price, but the Scat cranks have the advantage of being better steel and are nitride hardened. The extra money needed to buy a new Scat 400 crank will look insignificant when the stocker breaks. - 100% Return GUARANTEE! Keep in mind that if you spend money on a stout bottom end, you can always add more power-producing parts later when finances allow. NEW CHANGES TO OUR PHONE HOURS ! As a supplier for professional Top Fuel, Cup Car, and Trans Am among others, this company knows what it takes to make a crank live. Lightening and Rod Balancing on the Cheap. Excluding for the moment short-stroke exotics, this means using a 3.48-stroke crank. Here is a thru-bolt I-beam rod that I reworked for a 383 back in 1999. Currently my number-1 recommendation for a serious but budget constrained small-block build—this Scat Premium 7/16 rod is light, strong and has the minimum of bulk around the crank journal end. When used in a 350 this not only gets you a new stronger crank but also a big chunk of extra output. The 400 crank’s counterweights reflect this because they’re only intended to balance this lighter weight. Find 350 Pistons And Rods on sale here with the largest selection of 350 Pistons And Rods anywhere online. This has the effect of significantly increasing fatigue resistance as well as delivering about a 5- percent increase in tensile strength. The definition of the engine’s rod/ stroke ratio is the center-to-center rod length (B) divided by the stroke (A). First, if you have the powder metallurgy rods you will not need to balance them because they are, for the budget builder, close enough as is. Copyright © 1995-2021 eBay Inc. All Rights Reserved. A rod/stroke ratio of about 1.8 to 2:1 would be about optimum but with the block heights and stroke lengths we are using here, that is not a practicality. When Chevrolet opted to go shorter on the 400 rod, the result was a lighter rod/piston assembly than the 350. What I have done here is to detail the entire cast crank with my die grinder. This rod is good in a 350, but for a stroker application it needs the shoulder, and part of the shoulder end of the rod bolt grinding to clear the cam. Built by Chevrolet in great numbers during the early and mid- 1970s, the bulk of these engines became due for overhaul in the early 1980s. The principle alloying element for an aluminum alloy intended for piston usage is silicon, and for that you could read “glass.” Up to about 12-percent silicon will dissolve in aluminum, and any excess above that disperses “as is” throughout the material in the form of crystals. But let me remind you that, at the end of the day, the best deal is to get the entire rotating assembly (pistons, rods, damper, etc.) In terms of upgrading to a stronger and possibly heavier rod: though safer, it’s as bad to over-rod a performance engine as it is to under-rod it. If you must use a raised crown piston to get the CR up to where it’s needed, then limit the dome height to no more than 0.150 inch. Last on the list is my favorite. When looking for a used crank, you’re likely to see a variety of brands. Icon Chevy 350 Forged Pistons, Flat Top, 6.0 Rod made by Keith Black, for as low as $549.99. Buy It … If, when torn down your core unit’s crank is in good order, then, assuming a very tight budget, a crank journal is all that’s needed. This is the Premium 7/16 rod. Now consider this: after possibl spending $125 on a crank regrind, what are you left with? The Spiroloc pin retainer presents the biggest challenge to the novice engine builder. First there are the old-style forged steel rods that were used up until about 1987. FITS 2PC REAR MAIN SEAL BLOCKSImportant note.Our user id is: skipwhite, and our store name is whiteperformance1. If you were fortunate enough to pick up a later 360-degree one-piece rear main seal block, Scat has stock- and long strokes available for this application. For that reason alone it’s worth using only a 6-inch rod in any build. This is a relatively common process used in the improvement of mostly ferrous (iron) parts and is popular in the aerospace industry. These wide rings are almost always made of a relatively soft ductile iron and will bed in quickly. Buying a custom piston allows me to specify what I want for rings and this can prove a worthwhile power asset in itself. Wear on crank journals is markedly reduced and fatigue life considerably increased. Thanks to all of you keeping us so busy the last few months we have to make a temporary change to our Phone hours. First let us consider the stock rod. These bending loads become measurably greater when the crank is of the external balance style.
