Performance Parts Buyers Guide - Power package Buyer's Guide

Power Package: SysteMAX II for '67-'86 small-block Chevys
What's Included: Camshaft, lifters, intake manifold, timing set, hardened pushrods, aluminum cylinder heads, and ARP head bolts
Some Details: The Performance Engine System would like to help you make 425 hp and 400 lb-ft of torque. Got a problem with that? The components come with heat crossover passages and 68cc combustion chambers. The intake runner volume is 185cc; exhaust is 68cc. The Lunati cam was engineered for greater air-charge density, maximum mixture combustion, and constant port velocity.
MSRP: $1,700

Power Package: 454 Motown short-block assembly
What's Included: World Motown small-block, Eagle connecting rods and crank, Clevite main and rod bearings, Mahle forged pistons, and Total Seal or JE ring set
Some Details: Mmm torquey. The small-block assembly has been bored to 4.250 inches, honed, and fully prepped, and there's a 4.000-inch stroke forged-steel crank. The connecting rods are 4340 forged 6.000-inch H-beam style.
MSRP: $4,295.95

Power Package: High-Performance EFI for Toyotas
What's Included: Street Performer exhaust header, oversize big-bore throttle body, Pro camshaft, and K&N fuel injection
Some Details: The 16-gauge, mandrel-bent header has a 2-inch collector, and the throttle body is designed to increase airflow 12 percent. The stock air-cleaner assembly is replaced with a free-flowing F.I.P.K. kit and retains all emissions equipment. All told, expect up to a 30 hp gain.
MSRP: $1,050

Power Package: Ultimate HEI kit for early GMs
What's Included: HEI module with built-in rev limiter, rotor, and cap
Some Details: For non-computerized HEIs (four-pin module). The Ultimate has circuitry designed to produce 50 percent higher coil drive currents over stock-which translates to higher spark energy. The cap has brass terminals for spot-on conductivity. There's also a new dust cover.
MSRP: $164.30
