Hello all, I am new here. I am in the process of helping my father restore his 1971 Mach 1 that has a closed chamber 351 Cobra Jet. I really wanted to build this car right the first time, and I was confident that I was choosing the right camshaft for the engine build until I found this website.
Here are the details. The car currently has 4.11 gears and a C6 automatic transmission. We intend to just drive the car to shows, and occasional spirited driving on the weekend. It's not a race car, and will never see a track. However, we do like to go WOT as well with a little better than stock power.
I am planning to use a Holley Street Dominator Single Plane Intake, and 750 carb. I always figured the 4V loved to breathe, and I assumed the xe284h hydraulic flat tappet comp cam would do the trick. I really thought I could use the stock rockers and simply just upgrade the springs. Well after reading the street cams page on this forum I feel I have made a mistake in buying the camshaft. Since it seems I will need to do a lot more work than expected to make it work. Of course we are planning to completely overhaul the engine, but I want to use as many stock parts as possible.
Camshaft Specs of the hydraulic flat tappet xe284h are:
RPM range: 2500-6500
Valve Timing: 0.006
Lobe Separation: 110°
Intake Centerline: 106°
Duration: Intake 284, Exhaust 296
Duration @ .050" Lift: Intake 240, Exhaust 246
Valve Lift: Intake 0.584, Exhaust 0.588
Lobe Lift: Intake 0.339, Exhaust 0.341
The main reason I chose this camshaft is that I have an xe274hr in my mustang that has a 331 stroker. The car drives perfect on the street with a 5 speed, and makes really good power. So I assumed I could step up to a larger camshaft for the 351 since it's a larger displacement engine.
What I really want to know is how bad of a mistake did I make buying this cam? Am I wrong to assume that the xe284h will work fine with the correct stall converter and 4.11 gears?
Sorry for all the questions, but I just do not know much about 351 clevelands.
