242/248 here, 65 mile round trip daily.

242/248 drove it all over the place. It had a 5200rpm converter too. No thruway time except for short 2-3 mile jaunts, but took it to work and farted around a lot.

230/245.

Put 80K on it, love the power delivery.

I hated it at first then I realized the reason it idled so bad was a few vacuum leaks, and the reason I couldnt use the a/c at idle was a locking up compressor. new a/c system and fixed vacuum leaks and she idles and runs fine.

The only thing that wears on me is its loud as ****, even through a hooker cat back.

I like that the power comes on smooth and builds quick after like 3.5 or 4k. My buddy says its like vtec that actually does something.

Custom 243/251 .614/.621 110LSA in my 385, its a nice weather/autox car but I drive it to work and cruise around a lot in it. Also it's an M29 with stock 3.42's.

Your question is going to get really misleading results. The thing you need to remember is how well any cam car drives is always going to come down to how well the car is tuned.

Yah I knew two guys that daily drove Trex cams in LS1s, they had a lot of work on the driveability end of the tune. Lots of data logging and tweaking, but they drove better than my smaller cam on a mail order tune.

236/244 110 LSA, DD it for two years, has some surge in parking lots but nothing too crazy.

My buddy is tuning my 93, he actually daily drove it to work, 60 miles round trip through Houston traffic logging it and tuning it. The guys I knew who made big cams work like you said spent a lot of time on them.

GM847 with 3.73 gears. It sucked ***. 5th/6th gear were useless.

Now I have a 248/250 .650/.610 112lsa with a 396 and it can lug down to 1000rpm without issue. Drives better than stock.

I'm sure the 396 had a little bit to do with it.

Ive daily driven a GM 847 in a stock longbloclk manual car (234/242) and in an auto 383 car. Ive driven my current cam daily.
I never seen what peoples problem was with the GM 847, I tuned it myself and it ran great in the stock shortblock.

purpleflamzz

I dont daily it, but do drive it at least once a week, runs pretty good for a big solid roller. idles great too. Loud is an understatement
.254/.268 and .622/.638 112 LSA

Not sure what the problem would be with the GM 847 cam, I sold a 355" short block I had driven every day for two years to a guy that put that cam in it, along with a set of Lloyd's heads in a '95 M6 Camaro. It made 455 rwhp & drove just fine.

Biggest cam I drove on the street was in my old 383", 256-260 " .050", on 106 centers. Idled at 1200. Kinda annoying to an old man. Got a bigger one when I quit driving it. Mileage sucked. LOL

WS Sick

Yes, the mileage suck...lol

In my case if I had at least 4:10 gears everything would have been gravy.

NewOrleansLT1

Not really because I just wanted to know what guys are running out there. I'm not on the market for another cam..

93Euphoria

Heres a better question I see some of you stated: Whats the biggest cam anyone has or would drive on a bone stock bottom end?

WS Sick

I drove a GM 847 around on a stock bottom for years.
The set-up was stock longblock, GM 847 cam, k-motion k-800 springs (junk), Viginlante converter, Hooker LT headers, 3inch Y, Hooker cat-back and 3.73 gears.
Drank gas like it was free, but it ran very well.
