"Vintage" motor comparison
Jan '10 Hot Rod Mag, on the newstands, has their "Drag Week" featured with some great Fords--a '66 Fairlane 351W in the 12s, and a "new" 585 CID SOHC motored '64 Galaxie running mid 9s. Plus a (Duramax) diesel Mustang. Sure, it's mostly Chev-centric, but most of the Chevs at least have a 9" Ford out back!
But they also have a vintage motor showdown.
Shelby hi-po 289 vs. the 365 hp 327.
The 289 actually made 302 hp, pretty close to the stock Shelby claim of 306. The Chev was 356, with a little more torque. Some differences from "stock" and still "gross hp" probably, but....
1969: Boss 302 vs. Z28 302.
Both rated 290 to fool the insurance man, the Ford makes 372 horse and the Chev 356 with a touch more torque over a wider band than than the Ford.
1970 351CJ vs. Lt1 350.
Chev rated 370 horse, the Ford 300. On the dyno, the Chev made 353hp/392tq vs. the Ford's higher/lower 365/379.
1971 Boss 351 vs. LT1 350.
Both rated 330 horse that year, on the dyno the Ford outpowers the Chev again at 383hp/391tq vs the Chev at 359/376.
I graduated highschool in '71 and always thought the 351CJ and Boss were weak sisters compared to the 427s and 428s but they look pretty good now....

The SBC is a really good engine, but can't touch a Cleveland in all out competition IMO.
Were you not watching Pro Stock in he 70's? LOL!
For an engine with such a short life span they have certainly made their mark. Properly built engines with Cleveland heads are a force to be reckoned with even today.
