This is the cam in my car since the mid 90's and I've used this very same camshaft in 3 or 4 other 351-W's with great results.....
This camshaft is almost identical to the one Ford Motorsports used in their crate 351-W/350hp when they did build that combo.......

Using stock iron heads, they will need to be ported and polished very well for flow, stock rods and crank will be fine, you'll need flat top pistons, mine are the four vlave relief type, my compression is 10.2 to 1 and I run 93 octane pump gas with no problems.....
I'm running a 600 Holley double pumper on a Edelbrock RPM Performer dual plane intake....My heads are the older 351-W type, 1972 castings, ported/polished, I do have screw in studs and roller rockers....
The motor will idle all day at 800 rpms, not lopey at all (which I like) very smooth idle and pull like a freight train from idle to 5500rpms........
I've tried no less than 7 carbs (all Holleys) on the highway and at the 1/4 mile track on the very same engine, they ranged from stock 600 vac sec, to highly modified 750's and everything in bewteen.....The stock 600 DP gave the best mpg on the highway and the best 1/4 mile time on the dragstrip, the 3 , 750's I tried were the worst on the highway and dragstrip!!!!!!!!!!!
This combo will get you 350hp and probably more on the torque readings and be dependable and a joy to drive and easy to build.......
