This kit takes a 440 crank and rods, and stuff's 'em into a 383. The result is a 438. This one's a high revving screamer (just like the factory 383's were - but our parts are light years ahead of the old factory stuff,) with all new parts capable of 1000+ horsepower. The low deck, 3.750" stroke version of our Platinum Series crank used in this kit has the counterweights finished at the smaller "B" engine size, to ensure they will drop right into the block with no counterweight clearancing issues. Depending on the block used, many of customers find this kit drops right in with no modifications whatsoever! We now offer fully chamfered "B" engine main bearings as an available upgrade! We keep all the kits listed below normally on our our shelf and ready to ship, usually within 24 hours!
Additional Kit options: Upgrade to I beam rods and/or ARP2000 rod bolts: $70 Upgrade to Chamfered "B" engine main bearings: $50
