Default Who grinds custom cams?

I bought a new GM847 cam with all the valvetrain but I believe it just may be a little too large going off of some of the threads I've read. So I would like to have a custom one ground to use with stock heads but has that killer idle that the 847 has. Any suggestions??

With stock heads you could always still use an off the shelf grind the gm847 is big try something like the cc306 on a 112 its still a little big and would want to be rev'd high but has a rel nice sound.

GM847- 234/242
CC306- 230/244

I'd look for the 230/236 XFi grind.

Nothing wrong with the GM847, but you can contact Bret, Joe O, AI, etc. and talk to them. I'm sure they can come up with something for you.

It depends what you want out of a cam, the gm 847 could be the perfect cam for you or it could the the last cam you would want to put in your car.

Joe stop Grinding cams Earlier this year. The only way to get one is find a used one and then it'll be ground for someone elses set-up.

Putting a custom grind in a Stock head bottom end LT1 is kinda stupid if you ask me. NOT saying your stupid but, ther're are so many shelf cams that do well in stock motors it's not worth the 5-10 you might find in a custom. If you want big stick with the 847 or the CC306. If you want mid sized the 230/236 XFI is a good one. The only other cam i'd mess with would be the CC503 224/230. It's a good DD cam and should see 20-30 with a GOOD tune and good flowing exhaust.

You get more than just 5-10hp out of a custom cam + more power under the curve where you feel it the most

If the tuning is made properly with the cam it will be much better and make more hp than any off the shelf cam and who has only put a cam in there engine and not modified the exhaust and intake

There are three here in tulsa but i'm sorry i forgot you know everything. Custom grinds will ALWAYS make more power, thats the point. Your not teaching anyone anything. I IMO

dont see the purpose in a custom cam when you can hit the 360RWHP mark with a CC306.

Well,why woulden´t you want to have the car street friendly and make more and power under the curve with a custom then a cc306,why is the cc306 or any off the shelf cam better then a custom in your opinion?

The CC306 is very street friendly, as much as the 847 is. Why would someone dig for so much power on a " street car " out of a cam? This guy sounds like he wants to pep up his street toy not a Bracket car or even a weekend warrior. A shelf cam is perfect. They are easy to tune, everyone of them are "street Friendly" and it'll show 20-30rwhp over stock. Enough said.

The cc306 is one of the worst cams you can put in an LT1. It has EXTREMELY lazy lobes that kills the DCR and kills the lowend. A cam ground on more agressive lobes with the same .050" #'s would be more street friendly due to less overlap and would make more lowend due to more DCR. This is why I spend most of my time in the LS1 section, they have no problem trying new stuff and keeping up with technology, but most LT1 guys are happy using technology that is 20 years old.

LOL yeah the 306 is old as hell. With with overlap of the XE lobes doesnt it make it a nice decent nitrous cam though?

And hey, i ditched my 847 for a new BRE cam so i cant understand about trying something new and people over here using the same old things. Most just crack on a Summit and order the biggest Duration cam they can find and think it'll make power. I wouldnt have ever purchased a 847 if Lloyd Elliot didnt tell me too. I was wanting a custom grind the first time but he told me i'd do just as well with it for a what i wanted to do with the car.

You guys, I didn't want to make that big of deal out of this. My situation is plain simple, it is a DD and I will never take it to the track. I have street raced a few times but that's it. I just love the sound of the 847, and I don't have to have the newest technology out there I'm just kinda of a old school type of guy. I have all the bolt ons except a TB because I won't be making the power it needs for a upgrade. My car has alot of miles and I was going to replace the lifters and timing chain so I thought while I was in there that would be the best time to change the cam. My car goes as follows;
94 Z auto
LTs, no emissions or cats running through a GMMG
SS hood with Ram Air
PCMforless tune
What I plan on changing with the cam swap is a 2800 or 3k stall, shift kit and eith 3.73 or 4.10 gears. Other than that that's it.

I appreciate everybodys input.

Stop BSing the CC306 and Gm847 are NOT ideal for DD,if you are comparing them with a 355cid like you have then they are much smaller then a 350 with stock compression

230/236 would be the best for the open Exhaust he has,and will get better MPG then the other two and be friendlyer but with a custom you will do even better in both power and MPG
