[QUOTE="slantnosechevy, post: 1108800, member: 21514"] The 428 is good but the SD421 is better. The 421 was made for Nascar and handled those Mopars and Fords pretty good until GM pulled the plug on racing. Fireball Roberts was an early Dale Earnhardt and rolled those Ponchos in victory lane often. Love to find a nice '73-'74 Firebird w/ SD 455. Those Super Duty motors are some of the very few motors produced by anyone that would gain 100hp just by putting on a set of headers. Ponchos all gain from headers because of those big exhaust valves, but the SD's really gain from the head design. They're pretty close to a hemi design. I've got a '66 Catalina 2+2 421 4-speed posi staked out on my route. It's a ragtop w/buckets. I've been workin' this guy a couple years.....he's growing weak and his wife is helping me. [/QUOTE]
