The rods are forged H-beam-style components from Callies' subsidiary Compstar. They're 6.100 inches long and super tough. They also use 12-point bolts rather than a stud and a nut, effectively providing more clamping power and slightly reduced mass on the reciprocating assembly. | 
Fully floating wrist pins are used, which are easily slipped in after the rod ends have been inspected and/or honed. Tanged, round wire locks hold them in place. | 
There's nothing exotic about the ring pack design or the rings' materials. For this naturally aspirated assembly, the ring pack is similar to a production engine and the rings are simply moly-based. |
After the rods and pistons were assembled, they were carefully slipped into the iron cylinder liners. From here, the short-block is very close to completion. | 
The rods are secured to the crankshaft and the fasteners are final-torqued to 75 lb-ft. | 
Here's the finished Value Short-Block assembly. In its basic, as-listed form, it costs $6,950. Everything from the addition of a camshaft to a completely built engine is available at extra cost. As it stands, this sturdy, blueprinted, and forged-component assembly should handle about 600 naturally aspirated horsepower. |
With the Value Short-Block as its foundation, this 427 engineis put through its paces on one of Katech's engine dynos. Check out the snazzy valve covers and coil pack brackets. | 
Dyno results use an SAE J-607 correction factor, with peak numbers of 604 hp at 6,176 rpm and 566 lb-ft of torque at 4,415 rpm. |  |
