I'm not looking to buy the whole LT4 conversion kit. However, I'm interested in the hotcam on its own. Is it better to buy this as a kit (found on SummitRacing) or would it be better to peice it together myself? IE buy cam, differant RR, differant springs, locks, retainers?

Also, I have heard of stock LT1 valve covers not working with 1.6 or bigger RR. How true?

Any suggestions on what else I should purchase to go along with this cam? I think I'm going to invest in the HD LT4 timing chain. Mods are in sig. And I will have the LTs by the time the cam goes in.

 

My personal experience would be to look at other places other than the hotcam kit. I was hung on it too until being educated by the lt1 godfathers on here. My personal experience on my car has been. CC306 cam, roller tipped 1.6 rockers and edelbrock heads. The rockers do fit under the stock valve cover as long as they are not an aluminum bodied rocker. Either way you need to tune the pcm even with the lt4 cam. So plan on investing in lt1 edit etc. I did the obd 1 conversion on my car with long tubes, and magnaflow catback and 3:73 gears and lt1 edit for a tune. It is mean and will flatblow a hole in the wind and it has no driveability troubles. It is not necessary to change the heads but to realize the full potential of the package you need to or have yours ported. If you do not change the heads you need to upgrade the valve springs in the process. For the amount the hotcam is it is a relatively small cam. The trans is next on the list later but for now the stock converter has not pitched a bitch about the cam. The gears helped overcome the converter issue. I had them from an earlier project though. But, if hotcam is all you will consider it is a good kit that does work well it is just dated.

 

I was never a fan of the hotcam. Just my .02

 

My '94 doesn't have a cam, but it does have 1.6 full roller rockers. I have it under the stock valve covers with no problems. I bought a set of Proform rockers- imported but only costs $219.

 

Well I have to stay emissions friendly around here. If I'm not mistaken, the CC306 is a little to big for that. I'm pretty set on the hotcam, unless you can find one that is better and will still pass emissions with a tune. So, knowing that, do you still think i will need headwork with a baby cam such as the hotcam?

Also, if I do not buy the kit from SummitRacing, what RR do you reccomend? Springs, retainers, locks?

 

you will have to have a tune, eventually. i have a hotcam kit, alot of other stuff, dynoed, driven over 40,000 miles and its great. www.sdpc2000.com has it for $499. funny how everyone on here thinks the optimum setup for a lt1 is a 306 with long tubes. oh and no clearance issues with the bowtie rockers. that manual will be sweet iwith a hotcam and a good catback

 

Thats cheaper then I found it for on SummitRacing. Thanks. Ballpark number for this setup.... 330 wheels?

 

SO you are running the CC306 with the stock converter? I was under the impression this would not work. I am in the process of buying a cam, and was going to go with the Hotcam, but if the 306 will work on the stock converter and 3.42 gears, I will go that route. Are there any other cams in the middle of the Hotcam and the 306?

 

It's not terribly happy with it but the 3:73's helped overcome a lot of the initial problems with it. Once you get it rolling it's ok you just have to feather the gas when you put it in gear and take off. It's like a manual automatic. A trans rebuild and converter are on after paycheck time next week. There is nothing wrong with the one I have I just want to freshen it up and do a few upgrades while I'm in there. I just finished most of this about 3 weeks ago. I wanted the hotcam but everyone on here recommended ag it. So I figured what the hell and gave the cc306 a shot and I love it. Besides I figured if I did not like it I could just swap cams later on. I was not aware that you could even make a hotcam pass emmissions can you? Or do you just have to lean the **** out of the tuning and pull the timing out of it? I am just curious if anyone knows?

 

i have the hotcam kit in my car and i wish i would have went bigger. but its a nice cam. gives good sound and drives great. you have to tune your car. good luck finding things emissions friendly

 

Hows it run then?

 

I runs pretty strong. Honestly, once I let the new replacement springs heat cycle and laid into the gas, I could feel a bit of difference up top. Enough to get a speeding ticket.

 

It's all in what you personally want out of your car. To those who want a good-mannered, reliable, and fairly quick daily-driver, the Hotcam kit is a good choice at a good price (if you can find the good priced kits). With a solid tune, it will run great and can be a lot of fun on the street with its powerband. Should be fairly easy on the valvetrain with its low lift too...

Not everybody wants a hard-chopping, car-shaking cam that you have to spin really high to get into its powerband...Or needs an extra 10rwhp that they'll rarely use...I personally want something mild that will work well with my NON track daily-driver like the Hotcam...And it has a cool but surprisingly calm lope through a full exhaust with a good tune IMO...

If you get a good deal on it, go for it!

I had the hotcam kit put in my car this past summer just after i had my lt's put on and I cant be happier with it. For a bolt-on, cam only car its just fine, very streetable and I pass emissions without a problem. In a H/C or FI car the lt4 hotcam is way too small, but I really dont think you'll see much of a difference with a different cam on a cam only car.

I still have the stock valve covers over the RR's that came with the kit, no problems.

 

Yea...

 

I am going with the exact same setup on my daily driver 95 A4, except I have the Magnaflow exhaust and mail-order tune.

 

Ummmmmm.... yessssssss

 

348h/358t on the dynojet for me, but i have full bolt on mods to.

 

Nice numbers

I'm thinking maybe to skip out on the hotcam. Based on those numbers what do you think a CC305 w/ some ported heads would make? Still emissions legal?

 

I had been thinking about the hotcam kit also, but i did alot of research and decided to piece the things together, and go with a cc306 since college station dosen't test emissions. In the process someone in houston told me he was able to pass with a 224/230 and a tune (don't know about his heads tho).
