i just bought a GM Hot Cam kit complete with the 1.6 RR, valve springs ya know everything for my LT1, i was woundering what type of power gains might i expect from this, my engine is a new rebuilt with like 6k miles on it and its got some bolt ons. tell me whats up? thanks

 

Hate to tell you this,try a search.It has been covered thousands of times.

 

My engine builder refused to use the valvesprings that came in the kit. He said they were too weak to use, and would float. Might want to check into getting some new springs.

Anyway, I love how my HOTcam feels. I do have fully ported heads and I think that helps a lot, but I'm sure you'll like the cam too.

When I got my heads done, I switched springs because of the same reason listed above.

I gained 24 HP with the kit and an additional 11 after the tune.

 

I also got 35 to the rears after the hotcam kit and a tune.............weird.

i love my hot cam kit. just make sure you get some headers,i just dynoed 337 rwhp with my kit

 

Let me know when you get new times....we have similiar setups and I'm wondering what I'll run....

 

im on a tight budget are u sure im gonna float with the LT4 springs? arent those the ones that come with the LT4 heads on a stock LT4 vette? ??

 

This has also been covered many times, the springs that come in the kit ARE good enough, as i say though "good enough" is not "good enough" for some people though, many many people on this board use the springs that come with the kit with no problems what so ever, in fact i don't think i've ever seen anyone ever whos running the kit that has had a problem with the springs, however they are borderline, so if you changed the cam to ANYTHING bigger you would HAVE to have different springs, however if you dont rev indecently and abuse your new hotcam kit, the springs that come with it will work just fine, otherwise GM would not have put them in there, when they know the kit it a LT1 upgrade.

 

.....and if you do decide to go with different springs, you have to make sure that the new springs and retainers will work with the rockers that came with the Hot Cam kit......just a heads up, cuz I've been down that road already

 

is there anything extra i need with my cam kit i mean anything?? and what are the specs on the hotcam? does it have a nice lopey idel and also what is its powerband? thanks guys for all your help if i knew id get this i woulda read up on it more but me and my friend are in a hurry to put my car back on the road im tired of getting rides from my momy so i wanna do it fast and right. Thanks for all your advise and helpful input.

 

I would change the springs. The ones that came with the kit are made for the LT4 cam which is smaller than the LT4 "HOTcam" which is why they are borderline. You could probably run those springs without an issue, but why live on the edge?

Also, how far along are you in the install? You might need some new gaskets, assembly lube etc. depending on how far along you are.

My car has a lopey idle. THe guy that did my LT1 edit made it lope a little more noticeable for me..................
