GM Hot Cam? When replacing a stock cam in a 98 LS1 with a GM Hot Cam Kit do you need to replace the stock pushrods with shorter one's.

Yes. I would also do springs as well as a timing chain.

GM Hot Cam? I've replaced the timing chain and the valve springs. The instruction with the cam did not mention changing the pushrods. Any idea on what pushrods I should use with this cam. I think the lift is between 515 and 525?

my guess would be that they designed the cam to run stock pushrods.

I am 99% sure that cam has a stock base circle size so no you don't have to go shorter. Some good stiff chromemoly P-rods would deflect less and be an upgrade though.

if your doing a cam swap and already replaceing the springs and pushrods then i'd get a better cam then a Hot Cam. Go big or go home!
