The Updated Cam Lobe Profiles
OK, Brent has updated the lobe specifications. Here are my instructions, as I understand them. I'll place the order on Monday.
A custom solid flat tappet camshaft for a Ford FE core by Bullet Cams.
Both Intake and Exhaust lobes shall be FF284/357.
Lobe Separation Angle shall be 110 degrees.
The cam should be ground with 6 degrees advance so that when installed the intake center line will be 104 degrees and the exhaust center line will be 116 degrees.
If the lobes are not already nitrided, have them do that as well.
-------------------
FWIW, the FF284/357 lobes are spec'd at
Advertised --- 284 degrees
At .050 --- 255 degrees
At .200 --- 169 degrees
Lift .3570
Lash .011
Type CRA
