Does anyone have the hp/tq numbers on this motor. It came out of a 71 Torino Cobra. Thanks.

 

Try this site, it has engine specs for that motor.

Well I know that the 351c was only made for a short time in the usa but it is the no 1 V8 ford in Australia. Hp figures for the 1971 351 with a 4 barrel carby are 300hp factory rated, which is bull s**t, Ford did that so insurance companies would insure their cars. 350 hp or more was a more realistic genuine fsigure. The XYGTHO has been dyno tested at 385hp whereas Ford rated it at only 300. Torque is 360ft/lb or more. Two barrel option was 250 hp, but I suspect it was actually more. A 351 C can easilly produce 360-400 hp with no negative effects or significant loss of engine life.
The xygtho wasn't called the "WORLD's FASTEST 4 DOOR CAR" for nothing.
335C

 

What you've written all looks pretty right. But remeber, the standard GT DID only have about 300 hp, it was the HO that had the extra 75-odd hp. And also, remember that the stillborn 1972 XA GTHO Falcon was supposedly rated at about 410hp with 4v heads.

 

410 HP? I have never heard that figure but I wouldn't be surprised, the XAGTHO was massively powerful however I have been told that it had a slightly lower compression ration than the XYGTHO to make it more driveable hence loseing power - I don't know if it is true or not. As for the GT's being 300 Hp, they might have been, but I wouldn't be surprised if they were genuinely more, they went like a CUT CAT!!! and they pulled much better than many modern vehicles.

An interesting site, very much on this topic is :

www.fouronthefloor.com.au

Check it out, especially the articles, well worth the read.
335C.

 

I read it in an interview with the guy who did the first road testing of the phase IV at the skunkworks. He said they had about 410hp and could go up to 175mph. the interview was in Unique Cars, i think.

 

Thats sounds about right,

335C

 

I have a 351 c in My 71 ranchero is it the exact same engine as the one in a 71 torino is the hp/tq the same or does it vary?.

 

It varies.

remember, the early 2v motors only had about 210hp at the fly, not the 250 hp Ford claimed, but with a 4bbl intake and card, you can get up towards that 250

 

There are many similarities between the Ranchero and the Torino. From the dash forward was identical. If your vin code had 'M' in it for the motor (5th digit) then you had the same engine as an 'M' code Torino, whether it was a Cobra, GT, or 500.
I have the same motor, all original in my 71 GT. The Boss was later called 'H.O.' and featured 4 bolt mains and solid lifters. That was the only difference. There is room on a two-bolt main to machine the extra bolts in if you want 'em, but not necessary. The Ram Air (shaker) option added minimal power to the rating.

Ford started it; Ford will finish it!

 

The Boss heads were also machined for double valve springs and screw in rocker studs; which are modifications you would probably make to any performance cleveland anyhow (ie, any cleveland heads can be made into 'Boss' heads)

 

US Engines

A couple other variations are combustion chamber sizes. The 351B is a quench chamber like the Cleveland but slightly larger at 66cc. I haven't been able to see the difference, my only guess that they unshrouded the intake valve slightly. The 351HO is an open chamber, about 75cc.

302B and 351B used forged pop up pistons. The 351HO used a flat top.
302B heads are the only US heads without the 2 or 4 in the corner. Water passages were in a different location and the '70 heads were 58cc chambers.

Aussie Engines

All the large port heads installed on the Aussie Falcon GTs were made in the US. The Phase III HO engines were reassembled Cleveland 4V engines with many Boss parts added. A 302B 780 Holley, 351C intake with the heat riser passages blocked off, heads were modified for screw in studs and guide plates and used a 361B/HO mechanical cam, 351B H balancer, and crank journal clearance was increased by .001+ for High RPM. Headers were factory installed and so was a windage type oil pan. It may be the same as the 351B oil pan, I'm not sure.

The long range gas tank was standard on the Phase 3. 36 Imperial gallons which works out to 43 US gallons. I drove about 500 miles after a fill up and I still had 1/4 tank left.

 

Yep, 164L. It was also optional on the standard GT models and will fit into any XW/XY Falcon/Fairmont. They sell for around AUS~$300. Would make a nice change from my standard 75L tank, although I have heard that the big tank can cause handling problems when the level starts going down; the 150lb or so of petrol tends to slosh around in the back causing some unnerving rear end movement round corners.
