I have been pretty set on picking up a new GM hotcam. It does everything I want and sounds perfect for my application.
Can't talk me outta it

Specs are:
219/228 .525/.525 112LSA

The only thing is the fact that lobe technology has come a LONG way since then. And .525 lift, while being nice and easy on the valvetrain, is considered rather soft today, therefore, I was going to add some 1.8 RR as well and bump the lift up around .560

That got me thinking.... ..... what if I could get spec the original Hotcam with new lobe technology

What would happen if I specced a:
218, .605" XFI intake
228, .588" XER exhaust
111LSA
ICL - Don't know

Would a Hot-Chili-cam be a good thing?

Thought, opinons, insights and comments required
Also if you think I've completely lost my mind

I say you spec out an ASA cam with the new lobe designs!

I think you defeated the main reason people buy the hot and asa cam. that being they can run LS6 springs that cost $52. The way you specced it you would need atleast 918s and maybe duals

But what's really the difference in price between ls6 springs and 918s? $150, $200? But if you step up the cam, you will gain probably 20-30hp for that small increase in price for better valve springs.

PowerTalk

I think a set of 918s work well with XFI lobes so it should be sweet there.
Still a hell of a lot cheaper than 1.8:1 RR thats for sure

ASA Cam on XFI/XER lobes?
Not for my application but imagine how wicked THAT would be!!!

PowerTalk

Exactly

I was actually thinking about getting a custom grind with similar specs as the hotcam but with a bit more life and more duration built into it. I love the tq i get outta my hotcam!!

Just need to convince TSP to try it now

Sounds good to me

Actually, sounds awesome

well i dont think it is the lift that kills the springs, it would be the ramp rate. The seat perssure of the ls6 springs might not be enough once you get up in the rpms with that lobe design.

PowerTalk

100%.... 918 springs would be used with it

The real questions are:
- Would it work?
- Would it be worth it?
- Would it make gains (>20rwhp+) over the Original GM HotCam
- Are those specs the right ones to update this cam with 2008 technology

i dont think it is worth it, just get a proven grind like a tr224 it is easy on the springs and you know what you are getting with it. Because you will have to pay extra to have that cam made.

Ummmmmmmmmmm.......... Huh?

dont be a dick when people are helping you, and when they give you good advice. I never said only get that cam i said just look at that one. But i promise that tr224 is worth the extra $20 and it will **** on the hotchili cam all across the board. I also thing the 224 on .581 lift is a bettter cam then then tr cam on .566

mmmmmm chili cam I like it!

PowerTalk

Man, you said you don't think its worth it cause its unproven and would cost more than a TR224. Not the case. Thats all.

180ls1

iTrader: (4)

That is totally the case. the cam is unproven you do not know nearly enough about a cam to just throw parts about two cams to gether and hope it goes well. And you can get used but in good shape 224's for $200 or get a fresh grind hotcam for $100 so you are really not saving money. There are also other 224s that you can get brand new $250, I never said just ger the tr one i was just using it as an example please re read what i said.

how the f is he going to gain 20-30hp just from a change in cam lobes? have you not noticed the asa cam is consistently putting down 385-395whp...so you're saying that changing lobes will put you at or near 400whp? eehhh i'm not so sure. the cams work excellent as they are AND can utilize ls6 springs (as mentioned). i wouldn't put the additional abuse on the valvetrain for such a subjective gain in hp. i'd spend the $2-300 elsewhere, like an udp and tires or something.

i say the tsp224 cam in a second. unless you're just getting a smalled cam for sound. if thats the case run straight pipes and disconnect a vaccum line.

also i dont see why you only want to run 218 deg for intake. Why do you want to do that?
