That sounds about right... Also, the combustion chamber is 42.45cc, intake valves are 1.752 inches and exhaust valves are 1.417 inches. The rockers are 1.81:1.

That is where I found it too...

 

[Silver95Bird]

NPI cams:
.466" 186 intake
.466" 194 exhaust
PI cams:
.510" 186 intake
.530" 194 exhaust
1.8 rockers.
I know everyone uses something different, but based on direct measurements this works out. A guy on MD installed a set of Comps advertising .500" lift with 1.825 ratio, lift at the valve was .493", which works out to 1.8. As far as I know, all SOHC modulars use the same followers. Don't know for sure about dohc.

My Ford manuals show a 43.9cc chamber for an 01 GT.
Modular Ford numbers are het suxors, nobody agrees on them. Ford shows 2.02 and 2.03 rockers, but I know that's not right.

From researching PI cams...........

PI cam specs:
.505"/201 intake
.535"/210 exhaust
113.5 degree lobe sep angle

Is .505” and .535” the measurement in how far the valves get push in the cylinder ?

And can someone please explain 201 and 210.

This is all so new to me
