Default RE: x cam ??

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?

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

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.
