wondering what the differences between a 224/230 cam with a .536"/.544" lift and a 224/230 cam with a .502"/.510 " Also would you suggest a 224/230 or a "306" with stock heads Thanks

 

Its the same cam.... the low #'s are with 1.5X rockers, the higher with 1.6X rockers.

What engine are you talking about, so we know what "stock heads" are?

That way I can direct you to the correct tech forum.

 

the cams are on two different websites one is the cmotorsports 224/230 cam and the other is the thunderracing 224/230 cam both with 1.6 rockers that why i wondered what the difference was. The motor is a 1994 LT1

 

If both cams have the same duration @ .050 and are rated with 1.6 rockers the one with more overall lift will be a little more agressive with more duration @ points above .050 lift. The more agressive lobes will usually make more power until the point where you loose control of your valvetrain. The cams your talking about probably arent drastically different but the one with more lift could possibly float the valves sooner or like a little bit more spring pressure to keep the valves under control. If you have enough piston to valve clearance, good enough springs and good enough retainer to guide clearance to run the higher lift cam I would expect it to make a little better power.

 

Info from the TR website:
Info from the CMotorsports webstie:
Nowhere on the TR specs does it say it is with 1.6 rockers. If you go to the Comp Cams website, they show this cam as 224/230 .503/.510 w/ 1.5 rockers.

Still not convinced they are not just the same cam with different rockers.

In any case, LT1 cam selection belongs on "LT1 Tech". Moving it there.......

 

Fred is correct they are the same cam, also referred to as the cc503.

I think in this case, they are talking about the same 503 cam. But, Comp does make three different lifts in the XE series for 224/230 duration cams. At that point, you are into customs, but the lobes are there in the library.
