Was recommended this cam for my 383. I don't want to lose a lot of driveability as it is an everyday driver. Anybody have an opinion on it? I would be using 1.6 rockers as well with a 2800-3000 stall a true duals with bullets. That is about the extent of loss of driveability that I want.

 

With all the other stuff you have I would think it would work pretty well. A 383 would require a bigger cam just to give it that stock LT1 feel, and with a stall it should keep you out of the dead zone of the bigger cams. I'm assuming you have a good p&p job/aftermarket heads?

 

People run that cam with the stock bottom end all of the time on daily drivers. It is actually somewhat mild for a stroker, I say if streetablility is your objective, go for it.

 

Thanks for the replies guys.

Anybody else have any actual experience with it?

 

I will let you know in a couple weeks, I have the exact same setup (383ci, GM847, true duals) waiting to go in

 

I know people with bigger cams than that in the stock bottom end. Driveability is fine for them. It's all in the tune.

 

Running that set-up right now, no friveability problems whatsoever, and I'm running a mail order tune. Only surges occationally (in the right situation). it does drink the gas though around town, but gets right around 20 on the highway. I'm sure a dyno tune would help it out a little, but I havent had occation to (so its not bad at all).

I went to the track and in my full weight full optioned 97 WS6 T/A (even had the car seat still in place) I ran an 11.92 @ 115.4 mph (on a 1.72 60 foot).

On the street from stop light to stop light I have rarely been matched. And only then by a nitrous toting or heavily modded car.

 

Oh it's going to have nitrous on top of that.

Thanks for your help guys.

 

Just a thought: I find it interesting that it doesn't cost any more for a small cam than a large cam and yet the bigger cams provide more HP, but at the expense (so I understand) of pushing the TQ and HP up the rev scale.

To me that just means that I am going to (more than likely) suffer drivability and put more strain on the bottom end, i.e, jeopardize the longevity.

On the other hand, I've seen engines, including my own with a little bitty cam spin a bearing with less than 7 grand on the clock.

What's it all about ralphie?

 

RPM kills motors quite easily. There has also been a recent influx of DIY cam installers that have spun bearings. The general consensus is that the engine was contaminated during the swap.

 

I shift at 6200 with my GM 847 cam. The only thing I dont like about it is the stiffer springs I have make the lifters have a little more noise.
