Anderson Ford Motorsport cam specs?

Just give Rick a call he can narrow it down for you.. www.andersonfordmotorsport.com

If you have one of his cams It shouldn't be an issue, I have always found them to be great after the sale.

I call Rick before and he would not give me the specs of his blower cams. He just said that they were good

dont expect to get much out of them if you haven't bought from them. BTW I got my cam through them and am very happy.

I had a customer in a similar postion, I called gave him the lift number my guy had and we narrowed it down.... Once I got the motor apart I was able to confirm it with the numbers engraved on the cam. Brian K or Rick should help you out...

So the lobe lift should be around .308" on the intake side.

.308" x 1.6 = .493"

The lobe lift should be around .320" on the exhaust side.

.320" x 1.6 = .512"

Try not to judge the lobe seperation angle by the LSA. There are many factors that can effect the idle characteristics.

- Idle Speed
- Tune
- Induction
- Exhaust style/type/size
- Etc.

Besides, the LSA can be figured in many different ways.

5+5 = 10
7+3 = 10

Average them both, and you get the same average of 5, but yet there are two different ways to get the 5 average. Pretend 5 is the LSA. So...

Take the Z303 camshaft with an intake opening at 7* BTDC and an intake closing at 41* ABDC.

7+41+180 = 228* (duration). Divide that by 2 and you get 114*. Subtract the intake opening BTDC and you get 107* on the intake side for the intake centerline.

Now go to the exhaust side...

Exhaust Opening is:

Exhaust Opening: 51* BBDC
Exhaust Closing: 3* BTDC

51-3 = 48. 180 + 48 = 228/2 = 114*. 114* + 3* = 117*

So take the intake centerline and the exhaust centerline for each lobe.

107 + 117 = 224/2 = 112 LSA for the Z303 camshaft.

Take a completely different camshaft, the B303 with events of:

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

It has an LSA of 112* as well.

But, both of them have completely different valve events. The camshafts will behave quite differently.
