Can you racers help we with a cam selection for my '72 Gran Torino Sport, 351C 4V, 3.25 gear ratio, auto trans.?
I'm looking for a hot street machine with good low end torque.
Also I'm a little confused about LDA, what's the best way to go here for my application?
Another question, is there room in my heads for 1/2" O.D. valve guides without hitting water? Looks like this could be close!
Any help apreciated,
Tim

Sorry, with that combo it's not going to happen. The car is too heavy, the gear ratio too tall, and those heads tend to not make much low end torque as it is. 4v heads like rpm to make power.
Easiest way to get more "seat of the pants" acceleration of out of it, put a 4.11 gear in it.

the cars not that much heavier than a stang (mine according to a printout that came with the car from the factory says it weighs only 3600)...and i have 2.75 in my car at the moment
Tim, which tranny do you have in it?? i would strongly suggest a shift kit if it's a c6.

It may nbot be much heavier than a 71-73 mustang, but it is heavier, and they were some of the heaviest mustangs made. I would guess that Torino is somewhere around 3600-3800 lbs if not more, and that is heavy. Anyways, nevermind then. I forgot that I really dont know anything about 351 clevelands.

If you are only concerned about low end torque, put some Aussie 2V heads on it.
This of course will hurt top end power....
Really though you need more gears.....
Gears + 4V heads = more fun.....

Comp Cams 268H. Put a set of 411 gears in it. Edelbrock performer dual plane intake.You will not get hardly any low end torque out of a C with 4Vs. This combo is about as close as you can get. The 4V heads like high RPMS. An even better combo is 268H cam with 2V aussie heads. They make a bunch more torque on the bottom end. I have the 268H and Aussies on my Bronco and that motor (400) will haul that heavy truck real well. ------------------

Oh, by the way Dubz, it is a C-6. A overhaul with a kit is in the works. That is if I really do stay with the 351. If I go for
a 429 or 460, It'll be another C-6.
What to do.....Tim

Can't help with the Valve guides. I am not sure what you are asking.I still think the Aussies are less expensive than putting in a 429/460. More bang for the buck IMO. The C has a small block bell housing so you would have to get a Big block C-6 too.

Actually, this particular Torino is quite light. I was an factory experimental all aluminum model that was accidently shipped out to a dealer and then sold. Don't tell anybody!Tim

As I recall, by machinist mentioned something about it when he redid mine. Don't know much more about it than that.
