hot cam kit?
hot cam kit? im thinking about going with the gm hotcam kit after i get my taxes back. most know of the kit but for those of you who dont, it includes the cam, 1.6rr's springs and hardware. the car is a 94 bolt on formula with 120k. #1 is it worth the 500 some odd dollars for the whole kit? #2 how much does it effect gas mileage. im not extremely concerned about it but i am curious.#3 ive read that the cam is a .492/.492 lift. but in the cam kit in summits catalog it says it is .525/.525. is this because they are measuring the overall lift with the 1.6rr's as well. just a little confused about that. and finally for those of you who have it, how does it run, drive, and sound. sorry for the nit picky ?'s but i just want to be sure it s what i want to buy. thanks
Get ready to be told that it is a mistake to go with that kit. But honestly I think it is a great kit. Full boltons and that kit could get you around 325-340 depending on a4 or m6 and other stuff. I have heard that the drivability is like stock but it moves pretty good when you punch it. Hope this helps
I know people will say there are better choices but I have use the Hotcam on two builds. One was in a 95Z that had mild home ported heads, 58tb, LT's and dual exhaust and made 353 rwhp. the other hasn't been on the rollers yet. I like the street manners of this cam, it gives the right lope and can be made to pass the smog test if needed.

the cam is good but the springs are not!more pressure is needed they are barely 100,factory is 82-85.i have used the cam but the springs were aftermarket 125-130lbs.makes a big difference..

hot cam is old technology. there are better cams that use about the same lift and duration but make more power across the board. if you want more power that is, but then again if you dont want more power then why would you want a cam? just for the sound? cause the hotcam doesn't sound much like a cam... (sorry for thinking out loud)

I can vouch for some pretty good performance, thoug i didnt get any dyno #'s. I installed one in my cousins 94z with 176,000 miles, and it went from a 13.5 @ 101.36 to a 12.768@ 106.89 with dirty filters.. so i can vouch for decent performance. I will say though THe valve springs are crappy, and they are peaked out @ .525 ( which they were orig designed for the 96' Vette GS LT4 330Hp cam),so we sold them and put in a set of Comp cams 987-16's dbl springs, and they are awesome.. we also had a stock rebuild done on his heads so im sure that that helped a lil bit. Other than that, it was a huge improvement over what we were getting out of it. Yes the .525"lift is with 1.6's , but if you dont want to use them, and want the same lift, Edelbrock has a Performer LT1 cam that is the same specs as the hotcam but with factory rockers. as far as the hot cam on my cousins Z it sounds great , and performs great. It is all in what you want though... just my .02 . Hope it helps....
A useful post consists of 2 parts. A) opinion B) explanation to backup opinion.

Go with something better. I am not saying go bigger, but definately go with a newer grind or a custom one suited to your needs. I have always thought the hot cam wasn't a very good cam.

We had a guy hear in Hawaii that had a hotcammed LT1 Z that was a solid 12.8 car. And We are like .3-.5 slower than you guys on the mainland. Be it he had a 2800 stall, a gear change for an M6 would probably get in the range he was running. Think he said it put down 350-360ish. Car sounded good too.
there are definitely better combos out there but you'd be hard pressed to put one together for the price of the hotcam kit
so lets just tell it how it is shall we? there are better combos out there but with the hotcam kit you get the cam, rockers, springs, retainers, locks granted the springs are marginal at best but you still cant beat the price, i think thats the reason the hotcam kit has a lot of appeal

I'll eventually go with a bigger bumpstick and have my heads worked but for now I'm happy with the HC. 12.40s at 114mph at Beech bend 2.03 60' time.
Locally it went 7.83 at 90.3 in the 1/8th 1.78 60 foot. Still gets about 27mpg and my wife drives the car.
I have a pretty short list of mods. HC, headers, gears, PCM4less tune.

I'm sorry but if you are going through the trouble of a cam install then you should be running a tiny bit better than high 12s. But, unfortunately high 12s is about the fastest I have seen the hot cam run NA with stock heads and cubes.
Go with something better. I am not saying go bigger, but definately go with a newer grind or a custom one suited to your needs. I have always thought the hot cam wasn't a very good cam.

Well i agree, as now my cousin wishes he went with a bigger cam, but the work is done, and now he has somebody who wants to buy it.Plus it is still stock geared, and stalled, so he would have def benefited more from the 3600 fuddle that he bought for it, and the 3.73's.. but now they are mine.. ha ha! So i guess that means we'll soon have a clean slate to set his next one up even better. I on the other hand am going a lil big for mine to grow into when i upgrade later. my cam will be a custom grind 236 /242 @.050" .571"int / .591" w/112lsa. Yes i know its kinda big, but when im done with it, itll be tons -o-fun

Hey guys I am really sorry to revive an old *** thread but everyone is shooting down this hot cam (in which I was seriously considering) but none suggested a sure fire replacement cam. Also what would an LT1 run bone stock with a Hot cam kit only? Sorry to ask so many questions but I'm a very carefull buyer and want to know everything there is to know before committing
