Power advantage between Ford 351, Mopar 340 and Chevy 350??

Many of the SBs were put through their paces here, results published in Top Aussie Supercars.

351 Cleveland v 340. "We managed 15.5s in the Charger, while the Falcon was battling to break 16 seconds". "The 340 is definitely smoother at high revs & it doesn't have the 351s tendency to lose it's tune after hard use..."

350 Chev in a 3240 lb car, 275 hp, QJ carb. Best 1/4 mile was 15.8 sec.

The locally grown Holden SL/R 5000, with the Holden[ GM ] 308 V8 engine, was a thinly disguised race car. Weighed just 2610 lb. 15.8 1/4 mile.

The fastest car tested....drum roll....was a Val Charger with the 265 cu in inline 6, triple Webers, 302 hp. It ran a 14.4 1/4 mile. Silky smooth engine, pent roof combustion chambers. Chrys engineering at it's best. Road Tester's comment:"...you can drive around town at a steady 1500 rpm-30mph-& never feel the need to change down unless you want hard acceleration". Fastest run was 132 mph.
It beat the Ford Falcon Phase 3 HO with a 351 C. 14.7 1/4 mile. This thinly veiled race car was a pig on the street, & fools dribbled at the mouth over it; in the US it would have option box ticks for a 4 door car. This car had 'better' manners than the Phase 2, & the road testers had this comment: " It will crawl along from 1500 rpm in top, although of course, such a high compression 11 to one engine doesn't entirely hide it's displeasure. This sort of low speed flexibility was non-existent in the old car; it bucked & shook at 40 or below"
