1. Carburetion duties are handled by a Mighty Demon 850 mixer squirting through an 85/93 jet combo; the intake is a tried-and-true Edelbrock Victor Jr. 454-R.
2. Patriot Performance's Freedom Series aluminum big-block heads feature 320cc rectangular intake ports along with 2.25/ 1.88-inch valves. At $1,495 as delivered, they're a steal.3. True to its street/strip mission, this cam/ heads combo yielded 674 hp at 6,300 rpm, but also maintained an exceptionally broad torque band that peaked at 624 lb-ft.
4. Isky Red Zone lifters, one-piece pushrods, and 1.75:1 roller rockers complement the stout solid roller cam. 5. Hooker 2 1/8-inch Super Comp headers deal with the burnt junk.
6. The JMS Racing Engines' short-block runs a 4.350x4.250-inch bore and stroke combo to create 505ci. The two-bolt main block uses ARP studs for strength and comes with forged rods and KB Performance pistons. Compression checks in at 10.5:1.
