Horsepower differences.. GM847 vs. hotccam ok i got a pretty much full bolt-on, port&polsihed headsand intake.... with a hotcam 94 M6. now i was talking to a guy and he said that i might not even pick up much power going from the hotcam to the GM 847 .... i was wondering what some of you guys opinions were...... yes i've tried searching........?
Do you want a car you will continue to enjoy driveing everywhere or do you want one you will endup getting tired of. That is basically what this question comes down too. IMO neither is a good choice, the HOT cam would be servicable but the 847 on a stock shortblock is foolish.
the hot cam is a waste of money IMO. its just as hard to put a hot cam in the car as it is a properly sized cam but the hot cam yields what, 20-30rwhp max? thats not even worth the time and effect to me.

847 well I get 22mpg highway with mine, and 15 normal getting on to it. I dont have any problems driving it everyday. With lockup or a 6 speed cruising around isn't bad at all. Its really fun to drive and turns every head. with the 847 and just ported heads on my old setup. I ran 108 through the 1/4 and I switched to the 383 with the same topend and now run 114 but better times and speeds to come, I'm doing alot of things now that I didn't have the money for when I started. The only problem You'll have is if you have a lead foot like me and run around shifting at 7000+ all the time you'll do what I did and spin all the bearings out, but if you keep it below 6500 you'll do fine.

Its funny nobody answered this guys question. The question was does the 847 make a considerable difference in horsepower over the hotcam. He never said anything about driving it every day or streetability or anything like that.

Often people ask the wrong question and it is much MORE HELPFUL to steer them at the right question.
I know a couple locals who went with 230 intake and in the end they enjoyed the cars less.
Don't let people talk you into too big a cam. MUCH better to error on the milder side and be left wanting more but still enjoy the car. I hate to see guys make cars too aggressive and then not enjoy the car anymore. Makes it hard to maintain interest so you can get it right.

just put the 847 in my car with le2 heads and a 2800 stall. i dont know why people say the 847 couldnt be daily driven. so far ive had no problems with idle surge, bucking around town or nothing! u will notice that the cam doesnt start to pull until after 3000 rpms, but once it starts to, say goodbye, because it pulls hard!
i to have been thinking of a cam. i'm gonna do a rebuild but i'm not sure if i should just turn it to a 355 and put a descent streetable cam or just leave it the 350 and do all heavy duty **** for the rebuild. Put a Hotcam in and maybe keep stock heads. I just want it to be faster then the average bolt on LS1. I don't care about killing all when they line up with me. I'd like it to not have much of an agressive idle but really notice a mid to upper RPM pull. ~Cole~
