We have the ability to custom build you just about any combination the way you want it. Getting ready to build a 406 small block, starting out with the block only. Our short blocks have become a huge hit among racers and performance enthusiast all over the world. 006-inch preload, which is very close to zero lash when up to temperature.CNC-Motorsports, has quickly raised the bar to a new level in offering high quality short blocks at an affordable price. The limited-travel lifters eliminate that possibility. In terms of engine speed at peak power, the build was right on target for our competition's. All our short blocks are 100 machined, CNC Machined and blue-printed to. 160 inch of travel for the lifters to collapse, especially with high spring loads. Henderson's Chevy easily surpassed the 600hp mark, topping out at an impressive 612 hp at 6,300 rpm. We have the ability to custom build you just about any combination the way you want it. As Henderson points out, "With a hydraulic roller at this rpm range you do not have to worry too much about lifter pump-up, but there is. 010'/.010' resized stock rods with ARP bolts Speed Pro H601P pistons (These are dished) 4 bolt block bored. The 406 is a big-block Chevrolet V8 engine built from 1966 through 1974 by General Motors. Nothing needed to be clearanced, just normal machine work. The cam puts the power where it needs to be in the rpm range." To work with the cam, Henderson used a set of COMP's limited-travel retrofit hydraulic roller lifters. Built it for making all of the power under 6000 rpm's to save money. The cross-sectional area is limited at the pushrods, and the flow is less than you might get from a canted-valve or Hemi engine. 050-inch lift "I had more duration in the cam than many of the other engines in the competition because I was working with an inline-valve 23-degree head. Henderson arrived at the specification of 246/251 degrees duration at. Henderson wanted to run aggressive lobe profiles and had a custom camshaft ground using solid roller lobes from COMP Cams. Looking to run in the Street Division of competition in the 2012 AMSOIL Engine Masters Challenge, a hydraulic roller cam was required equipment. Henderson tells us, "I wanted the oil to drain to the rear to keep the oil off the rotating assembly and reduce windage, and off the shallow side at the front of the pan." The two-bolt main blocks are a better starting point than the four-bolt block, since the aftermarket splayed caps are a stronger setup than the factory four-bolt main's." Besides the usual machining, block prep included general cleanup and grinding of the casting flash and adding stand-pipes to direct oil flow to drain back to the rear of the block. We just reinforced the original two-bolt main block with aftermarket billet main caps, and added a partial fill with Hardblock. The GM blocks are plenty strong for this kind of build, and with their siamesed bore there is plenty of meat between the cylinders to keep things stable. An aftermarket block would have been nice, but the stock GM block probably saved over $1,000 when all was said and done. As Henderson tells us, "The block came out of a 1976 Chevy Blazer that was left out in a field so long, a tree was growing out of it. Soon thereafter Warren started focusing all his energy on tooling up and getting the proper equipment to build aluminum castings.
