Default Hot Cam...

Been doin alot of research on which cam I want for my M6 Z28...
I want to be smart about it and not over cam my car, and I dont wanna go to small and it not have any sound....
I was thinking of getting the Hot Cam KIT... Ive seen the cam in action and it is very impressive for it size, sounds good and I hear the shift points arent that high...
Does anybody know the pros and cons of this cam... Or would recommend something similar in size and is safe...
People say RPM=HP and I understand that but Im willing to sacrifice HP for Saftey...

What do you think?

I just did the hotcam over the winter, it deffinitely makes your car sound WAY better, its a nice little cam, and does have some lope. people on this board hate it tho, and your going to get alot of "go bigger" replies or " go cc503" blah blah.. It turned my m6 z28 into a completely different experience across the board, being my daily driver I wanted to retain almost all my mpg's,, not have to rev high and just add some nice sound and power all of that is great for the hotcam. easier on my 104k bearings and still good on gas.

cc305 is very comparable now if u get the 112 lsa it will cam lopey compared to the 114 lsa which will sound stock both of these cams will make a more power than the hot cam + u can rpm a bit more too. but its all up to u and what sound u want and powerband

if i were to do it all over again to tell you the truth i would peice my kit together, and use better quality parts. Since the lt4 valve springs are kind of wimpy and barely support the hotcam in my opinion, i will be switching springs soon on my kit.

Well why would I need anymore supporting springs if I was just goin run the Hot Cam? Isnt it all tuned for each other...?

If you do decide to run that cam I would piece it together separately because the lt4 springs are pretty weak and crappy and the rockers are not the best either. If you want the shift points of the hot cam but want the power of the cc503 I have a cam in mind for you. Check out the Advanced Induction 218/226 .540/.540 112lsa cam which is known to make up to another 15hp/tq than the hot cam and is essentially the same duration. Also has a much better lobe design over the lazy lobes of the lt4. Just something to look into.

Hot Cam Kit sells at a decent price, but I recommend go ahead and get stronger valve springs. You won't regret it.

i ended up with the 10308-1 crane spring kit, but had to buy -.050 retainers and 10 degree locks so they would clear the 1.6 roller rockers in the hckit

I put in the hot cam kit 3 years ago. Never given me any trouble but I live in a place were no one runs these cars and if they do there old guys who aren't interessted in moding them. Point I'm trying to make is that I had no venue for comunicating with other lt1 owners. I just found this site a half a year ago and if I knew then what I know now I wouldn't put that cam in the car.

It's not that I'm not happy with it but I mean why have just more power when you can have the most? I think in general a guy is gonna tell you if his decission was a good one or not so, if enough guys are saying there is better stuff out there what reason do they have to lie.

Further more, in my oppinion, I like the idea of AI. They got it figured out, talk to them and decide what your gonna do with your car, get a few profesional opinions. Is cam the only thing your gonna do? If so cool, but if not plan the cam for your other mods.

Yes they would work for the hotcam, since they come with the kit. But they're not great springs. i KNOW i will gain more when i switch springs, because i run mine up to around 6500, and after 6k mine just rolls over and dies basically.

A buddy was running a simular cam grind in a 3rd gen tpi with a aftermarket intake, He was using the lt4 springs also, had the same issue with his, we but in comp beehive springs now it keeps pulling up to about 6400 or so.

So like i said before id peice it together still if i could do it all over again, and I didnt know about the AI cam before, but that looks like another route to go.

And to answer your question about pushrods, Mainly any self aligning pushrod you use, it can be with stock push rods

NSA RR's require hardened pushrods and aligning plates.

People put down the Hot Cam but its a great deal for the money, and i have a friend who runs low 12s on a 75 shot, with long tubes, gears, stall, etc. Good deal for small budget

Nothing wrong with the Hotcam...proven performer for sure. It's not going to set the world on fire, but it all depends on what YOU want from your car. I like the CC305 if you want a little less lope - it's easy on valve train parts and makes nice power, and it likes a little spray as well.

yeah, a properly setup cam-only car can run low 12's all day long. Just need to have the properly matched gearing/stall size and the suspension/tires to put the power to the ground.
