I have a '74 Torino wagon with a 351C 2V and an FMX tranny (eventually
a C4 when I get ambitious). I'm looking to get as much street
performance as possible out of it while staying within a reasonable
budget (approx. $1500). I'll be doing the majority of the labor
myself, but am wondering precisely what would be the best hardware to
use. I've never delved much into building engines for performance.
Here is what I have come up with thus far . . . am I on the right
track? Any ideas as to a purely ballpark figure as far as torque/HP
Edelbrock 1406 600CFM carb
Edelbrock RPM Air Gap II intake manifold
Comp Cams 268H Camshaft/lifter kit
Hooker 6921 headers
Custom dual exhaust with X-pipe and Flowmasters
MSD Billet distributor
You're on the right track. The 600 cfm is an excellent choice.
When you go to degree your cam, run it straight up - not retarded or
advanced - for excellent street performance.
Ford was transitioning to DuraSpark in '74. If you have the DuraSpark
ignition, stick with it. My recollection is that some 302 Mercury's had
this electronic ignition, the 351 in a Ford grocery-getter probably
still has the points, in which I would recommend the Pertronix "Ignitor"
conversion from www.vintageperformance.com/retrorockets/ .
You won't need the MSD hardware with the ~ $100 Pertronix kit. It's
overkill & complex, the $$ can be spent better elsewhere.
With the headers & X-pipe, you will have plenty of flow & relief. The
Flowmasters will be overkill too, the drone will be bothersome. There
is a factory style over-the-axle dual exhaust for your application -
then you can use Sears "Muzzlers", or Midas, or Walker mufflers w/
warranties & factory style hangers(interior noise reduction... again).
Folks are going to scream when I say this of course, but if you dyno the
car before messing with the ignition, and dyno it after fiddling with the
ignition, you won't see any meaningful difference.
The factories went to electronic ignition because you don't have to
adjust it. But if your wanting to performance up this car, the whole
point is to tune it, right?
Which is why I recommended the Pertronix conversion. This will
eliminate the points as a variable in a 33 y/o car while "fiddling" with
the rest of it. The basic Pertronix Ignitor is good to 6K-7K rpm no
problem... way beyond what is needed.
