Hi Fellas,

Just bought a XE270HR-114 comp cam for my eb falcon, which has a 302 windsor running GT40P's and explorer manifold. The car is running a full GRA Setup with one converter and carby.

Xe270hr-14
270/276 advertised duration

218/224 duration @ .050"

.512/.512 lift

114° lobe seperation angle


With the above cam i bought the matching valve springs etc. My question is should i keep the standard 1.6 Roller rockers or should i be going bigger and if so what size??

Help me out here fellas

I'd stay with 1.6's.
1.7's would give you .544 lift which may cause you piston to valve clearance problems.
