What is the maximum lift a stock LT1 take without modications to the pistons? the cam i am looking at is this one
cca-07-466-8
Operating Range: 1800-5800 RPM
Duration Advertised: 268° Intake / 276° Exhaust
Duration @ .050'' Lift: 218° Intake / 224° Exhaust
Valve Lift w/1.6 Rockers: .570'' Intake / .565'' Exhaust
Lobe Separation Angle: 113°
Any good advice would help me out thanks.
Also,
I looked up this cam on the comp cams site and their specs say with 1.5 rockers. Jegs site says 1.6
Which one to believe?
If I go off comp cams site this cam would be .608 int. and .602 ex. w/1.6 rockers
This is why i am asking this question just in case if i have to get the pistons cut.

 

the lift figures are stated with 1.6 Rockers.
The XFI Grinds assume you are running 1.6RR and the 918 beehive spring

You will not have any P2V issues

 

I have seen .63x run with no problems on stock bottom end.

 

lift is really not the biggest factor in ptv clearances. fwiw, i have .644" lift with my cam. i did replace my pistons but they were actually a little taller than stock and they had the same size reliefs. Im also running a 0.026 head gasket and my heads were milled (2.0 valve's). there is more room than people think... best thing to do is check with some clay.

 

thanks guys i appreciate the info.
