Looking for some help to figure out the best rebuild for the Mach I'm restoring. Here's the setup:

351C 4V motor w/ quinch heads.
Block D0AE-L<--- 1970
Crank will be .020 under 4MA<--from a 1973 motor, nodular steel and brinell hardness number on crank.
600 CFM Holley, possible a little bigger if the shaker parts will still fit properly.
Stock Cast Iron 4V intake manifold.
Heads have been checked at 63CC. Valve size 219in. 171ex. huge.
I might upgrade the ignition. dual point?
New 2 1/2" exhaust

Rebuild - going with forged pistons .040 over.
Cam - ford made two differnet cams that came stock with the 351C and CJ motors.
Here they are:

Stock 4V motor - Hyd. 268/280 .420/.450L.
CJ Motor - Hyd. 270/290 .481/.490

These cams are no longer available. Need a good cam with at least as much performance as the stock cam, prefrebly a little more. I'm trying to keep the motor basically stock and I'm not trying to build a drag car. I just want it to run really good. thanks for your input.

These guys are the 'geeks' of the 351c and I mean that as a compliment.

I have this cam in my car, cannot really state how it runs as after installing the motor and breaking the cam in it had a noise so I took it to the mechanic and they think it a lower end bearing after checking the valves for noise and pulling the filter showing excessive metal so out comes the motor.

The motor is setup with edelbrock performer 351c heads and intake with crane roller rockers 1.73.

im using a compcams dual energy cam (275DEH) in my 351c it has a chopy idle and runs pretty well.
the specs are 515/541 with 275/285 duration. its great form 2000 all the way to 6000 rpms and produces superior mid range and high end gains. great for a daily driver that likes to show off on the freeway.

its also a rock solid cam to build on if you deside to go more racing orented too.

oh yeah i almost forgot its also a good cam if your running full ehxaust because it favors the ehxaust side of the engine which is something that clevelands need to run well.
