GM 350 vs Ford 351C

[Scott 02]

What are the specifications on these two motors? what has the more power. I don't give a crap about the torque readings.

Woah! Thats a hard question to answer, since it depends on MANY factors. There are many varients of each of those motors, and hp / tq values could vary alot.

If you want a stock vs stock comparison, give an applications of each engine and I will give you some rough numbers.

I know, i been looking around for the specifications on both but have had a hard time finding them. The torque is ok to know now that i thought about it. I been arguing over which may have more power.

Clevelands were manufactured dowununder from 1971~1982, sold until '84. Aussie clevos found their way into DeTomaso models (later Pantera etc), local F-Series variants, Falcon/Fairlanes of all descriptions, also exported back to the US in small numbers for racing, mostly for drags. Apparently our version was somewhat superior in quality, featuring thicker walls, smoother castings

They were a great engine, real deep-breather, fondly remembered. Here in stock-spec they outperformed equivalent SBCs. Note we got 302 Clevelands (small-chamber heads, short-throw crank) as well as 351 like the US in small & large port versions. From memory, some of our standard-spec Cleveland hp ratings were

302 2V > 240hp
351 2V > 260hp
351 4V > 300hp*
351 4V > 330hp#
351 HO > 350hp+

* = under-rated
# = DeTomaso spec (minimum?)
+ = Ford claimed only 300hp but some in reality had up to 380hp. Stock 1971 Falcon HOs easily did over 150 mph if their 6,150rpm rev-limiter was disconnected

My friend brought those specs. to school today. Still looking for 350 specs. though

Wher did you find those specs thunder?
Chech this out, I know that the 1970 chevy 350 stock engine was rated at 220 hp . As the years went on the hp and torque went up. So are those 351 numbers- 1970 numbers or 1980 numbers??

They're from memory although I am 100% sure of the numbers. My SAE Gross ratings apply to 1971~75 Clevelands although the hi-compression big-valve 351C variant was dropped for local Fords in '74. From 1976 emissions arrived in force here, we converted to a DIN metric rating system (ie: kilowatts) and the 302C became a 4V to maintain performance

For your own confirmation you might try exploring the 'Falcon Heritage' section of our local Ford Performance factory website, which contains specs. Keep in mind that most claimed performance figures in there are very conservative. I bought almost every car magazine in those days, their tested figures were much faster - eg base Falcon XA GT did 15.1 in the 1/4 mile, officially Ford only claim a 15.8, similarly 302C 2Vs were in reality high-16/ low-17 second cars .. not the absurd 18.6 as stated within

Thanks, yet nothing new. As soon as i find the specifications on the 350's in all the years of make they will get posted.

Go to an old book bookstore, lots of old repair manuals had HP and torque ratings for all US production vehicles.

Hey TD, that Falcon looks like the 70 Ford Torino.

I sure would like to see more of them Aussie vehicles, post some pictures of the rods you guys are rebuilding now days.

Here in the States, people are rebuilding more early 70s stuff than anything else.

later

You're right about the Torino kinship. Similar .. but totally different

I thought Torinos had excellent styling. Compare one with a 74 'XB' Falcon GT Hardtop

[waterdog]

TD, some nice cars man, are they yours?

The Falcon looks like a cross between a Mustang and Torino.

Pretty cool, got anymore?

[Thunda Downunda]

What's your preference waterdog? GM-Holden, Ford or Mopar?

[waterdog]

GM of course.

GM-Holden??, post'um I gotta see them.

Check back tomorrow. I'll start a new waterdog photo thread in the 'Holden' classification, look there
