This is a first line product from Scat engine products. Beware of sellers offering no name, (off brand) cranks. We have seen an array of problems with these crankshafts. Important Note. This crankshaft must be balanced with your pistons and rods before use. For use in big block Chevy engines with the 2 piece style rear main seal. 4.00" stroke crank. This crank requires the use of an external damper and flexplate or flywheel. Crank weight is approximately 70 lbs Counterweights are profiled for 6.135" connecting rods. 4.00 Stroke Crankshaft - 454 engines. 6.135" Connecting rod length required Must be balanced prior to assembly 2.750" Main Journals - STD 2.200" Rod Journal - STD 2 Piece Real Main Seal Much stronger than stock OEM cast cranks Chamfered oil holes for improved high RPM oiling Horsepower rating for this crank is approx. 800+ Listed below is an upgrade we consider very beneficial and requested by many. Crank polishing: Extends bearing life, reduces oil temp, frees up a slight amount of average horsepower. This is a very low cost upgrade, and in the world of mass production, most cranks do not come with a true polished finish. This is why most machine shops have a machine to do this. The difference is dramatic between a crank right out of the box and one that we have polished. Bearing companies claim that cranks that have better finishes on the journals will survive the break-in better, and have much longer bearing life. We do a three step process and bring the RA numbers down in the single digit range. We have the most advanced crank polishing machine on the market. We find this to be an excellent upgrade for your engine build, considering the low cost. We polish the crank for every engine we build. Cost for this crank polishing upgrade is $38.50 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this assembly you may add any of these upgrades to your shopping cart. Click here to add upgrades.
The appearance of the journals show a dramatic difference once polished. |
