I'm new here and was wondering about the LT4 hotcam. I have seen things about it before but I was wondering what all i would need to install it on my car. I want to do the minimum amount that I have to b/c money is an issue right now. Thanks for the help.

 

The hotcam is a decent cam if you're bound to emissions. If you're not, the options are out there for more/better power.

 

When installing the Hot Cam, or any other cam for that matter, your going to at least need a cam swap gasket set.

There are also other things to consider as well. I would take apart and thoroughly inspect your lifters before reusing them with a new cam. More than likely, u should replace them. Also, ur probably going to want better springs to match the higher lift numbers of the cam. Also, make sure u check over pieces that have a high liklihood of failing, such as waterpump, opti, and coil.

 

The HOTcam kit is $479 from gmpartsdirect.com. It comes with the cam, springs, roller rockers, retainers, shims etc. You'll also need a new timing chain, gaskets etc. I didn't replace my lifters, but you may need to according to wheelman, although I believe most people just reuse them.

I got by with using a stock replacement chain only which was $20. I felt comfortable doing this since I have an electric waterpump. You might need to do the LT4 timing set if you have the stock waterpump.

I had a few leaks from the timing cover after my cam swap, so be careful! Also loosen the oil pan bolts and let it drop down a hair so you can get the timing cover off. The timing cover sits in the oil pan gasket.

if you have the original opti, mine as well replace that too, doesn't that have to come off for a cam install??

 

also, if you have a limited budget, try the for sale section. that's where I bought and still buying everything I need!

 

Thanks for all the info. I really appreciate how helpful everyone is one this site.
