Default RE: x cam ??

when replacing the camshaft, remove the timing cover and waterpump as one piece.

2.Use plenty of lube on the lobes, any nicks or scratches and its over.

3.Replace the timing chain and both sprockets, both dots line up, not face 12 like a Chevy.

4.Install new roller lifters or soak them in Kerosene a few days, then inspect them for knicks or sticking/damaged roller bearings.

you arent looking at the total duration though, the valve events are different

If you want to sell the X-cam. Hit me up.

While the letter cams may be outdated, they are tried and true. Yes, there is better technology out there. The point of a dual pattern cam is to flow better on the exhaust side due to Ford heads having a crappy exhaust flow. AFR solved this problem. Hell, you have guys running an F-cam that are in the 8's. It all depends on how you build the motor.

wrong, a b cam with 1.7 rockers has a total lift of 0.510
x cam is 0.542

I stand corrected. Thank you.

I am sure power difference is very minimal though.

There are alot of good points made my 2 cents are this, I've seen alot of different combos working at the dyno, and the best street RWHP350 was with a zcamin a stock bottom end 185AFR! 302 ci 650 rpm air gap.That little of difference between cams may not be worth the time and effort. I would Put your effort into the heads my suggestion that where the powers at, I've seen stuffwith very small cams that shouldn't makebig power belt it out with good heads.But I agree with jtmustang do what you want!

WouldI have to get my pistons flycut to put in an x cam with gt40 heads? What's the difference between the foxbodys and the 94-95s?

Most likely...... nope, but you need to check anyway. The main difference, and against the SN95 engine, are the hypereutectic pistons.

What is the most safe way to check?

Not quite, they are the same.

Assuming you are talking about the lobe seperation angle, take this in...

5 + 5 = 10
7 + 3 = 10

The average of both is 5. Pretend that 5 is the LSA.

The LSA works the same way for both camshafts, because they have the same opening and closing events.

Intake Opening: 5* BTDC
Intake Closing: 39* ABDC
Exhaust Opening: 49* BBDC
Exhaust Closing: 5* BTDC

Take the intake side for simplicity, 5 + 39 = 44 degrees.

Add 180 degrees to represent the intake stroke (1/4 of a complete 4-stroke cycle) and you get:

180 + 44 = 224* (duration on the intake side).

Divide by two and you get the LSA - 112*. This works the same for both camshafts.
