Is the LT4 hotcam kit right for me....
The Hotcam is the best bang for the buck cam out there. It has alot of GM engineering which makes it an awesome streetcam. It has a 112 L/s which makes it just as powerful as the 305 or very close. There is are a couple guys that have run 11's with the hotcam setup and Ken did it with stock heads 11.80's to be exact and with 3.42 gears. I had 3.23's when I first put my Hotcam, headers and 2800 PI converter in. The first day at the track it ran 12.70's then only got better from there. It has run 12.30'@109.7mph in a full weight 3700+lb Transam with 3.42 gears. I have run 11.40's with a 125 shot and a crappy transmission. I would reccomend this cam to anyone looking for a good driver and racer. I will probably switch cams b/c I would like to run 11's N/A w/o sacraficing any creature comforts like leather interior or A/C. It could still be done with the hotcam but I need to change valve springs and i am just ready for something a little more radical since I don't drive my car everyday anymore. JMO Later
What if you get the 306, but don't have ALL the head work you plan on doing done at the same time? Will the engine be damaged at all, or will it just run like ***? Keep in mind, engine will have to make it through the break-in as well...
I would expect to lose some fuel economy with an aftermarket cam, but how much is the cam and how much is driving style. For example, I usually drive mine pretty easy (shift about 2K), with only an occasional romp to shut down a civic with a fart can. Would I totally eat it on fuel economy, like around 12 mpg city?
gas mileage can be lost pretty bad, I already throw in 93 octane, so its like driving a car with even less gas mileage, so its important to get a cam that works well in traffic, which you probably spend a good amount in. Sure many will claim X amount on the highway, but city is bad. What you need to look for is overlap, this means that both intake and exhaust valves are open at the same time, so more overlap means worse gas mileage, because the fuel is not always geting completely burned. A more milder cam is probably what your looking for, the cc306 will eat more than say the hotcam, which I've heard great things about since it has good numbers and street manners. I myself went with a nitrous cam, so I retain just a little overlap, good power, and the ability to extract full power with nitrous.
I laid down 330 with the hotcam on stock heads (in 100 degrees and 80% humidity)...
I went with the hotcam kit because I didn't have the extra 200$ for a "cc305 kit". From what I've seen comparing hotcam/305 dyno's is that the 305 has a little more midrange (due to the steeper lobes), and their top-end is almost identical... So I don't regret my decision at all.
