x cam ??

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?

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

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.
