Two camshafts are ready to go and get reground now.
This is the one that’s getting a mild upgrade.
For the geeks..
.365 lift, 244° @ .040 intake
.375 lift, 250° @ .040 exhaust
Stock is
.313 lift, 221° @ .040 intake
.303 lift, 221° @ .040 exhaust.
I have a wrecked cam and head that a certain company will regrind and convert to roller bearings .
This may be where my Big Bore money goes. A roller cam for these is a bit different than in a car. This conversion only changes the bearing surfaces to a roller. The grind can be sexy too though. .405 @ 221°?
Long story short. (I KNOW!)
Instead of doing a 500cc big bore I can get the same power with quicker revs by farting around with compression and camshafts!

Camshafts are most definitely witchcraft.

It’s fun witchcraft though. No other single decision can make the difference between a great engine or a boat anchor.
