A camshaft essay.

OK...I got peeved because I was sick of reading people canning the idea of carb induction ...so this is my little "eye opener" for all those EFI guys running aftermarket cams...


When I installed my Inertia SRT Max Plus cam...I was surprised to see it installed on a 114 ICL...when the Crower cam card supplied with the cam stated it should go in at 106!

A couple of international calls to Stu and it soon became apparent that Piston to Valve is a real issue with factory slugs in the G3...and the only way to get around it is for the cam suppliers to get these cams ground on a RETARDED ICL......by 6-8 degrees .......to get reasonable P-V clearance.

Trouble is...a retarded grind has the following effects....

- Reduces cylinder pressure
- Moves the torque band higher
- Reduces the scavenging effect at low rpm
- Kills low end torque


Of course...........these are things anyone running a carb inducted motor definitely DOES NOT WANT..

But hey...I'm 800lbs lighter than a LX car, I run qtr mile gears and a 3800 stall.


but what about you EFI guys running aftermarket sticks and factory slugs?

so,...this post is a bit of a crack at those that are assuming all our issues are "intake related" ..............put simply...they're not.

If you're running an aftermarket stick with factory slugs....you're still leaving plenty on the table...EFI or Carb! ......even in an A Body :p

But don't get too down.....makes you wonder how these guys with EFI 4300lb cars and 3.00 gear sets are feeling don't it? ;)
