LS7 cam in an LS1/6?
LS7 cam in an LS1/6? I have an LS7 cam I just took out and I am wondering if I can stick it in an LS1/6? I know a few people with these engines a little more cam never hurt anyone! Using the LS7 springs and retainers may an issue?
I can take a photo - it has a cam sensor looking item before the last cam journal at the back. Looks like a 1/1 type. The LS7 has one on the timing gear picked up by a sensor in the cover.

That doesn't mean a higher LSA won't fill the cylinders better at lower rpm. LSA is basically overlap, the smaller it is, the longer the intake and exhaust valves are both open. At lower rpm's this blows air through the cylinder making it harder to fill, however this helps at higher rpm's by helping to pull the exhaust gas out while pushing clean air in.
