 Subject: KRC camshafts
IP: Logged
Message:
I have a question and was wondering if anyone can help. I have a 97 318, with 2.02 heads, M1, roller rockers, computer, header/exhaust, ported TB, and currently have the R/T cam. I am looking to get a bigger cam in hopes of making more power. First is anyone out there running a KRC camshaft? what is your engine and setup? Im considering the 210, 210x or 220. I have no idea which one I should chose. Any help would be appreciated. THanks.

Nick, ask yourself what your future plans for the truck are. Then base your decision on that. I'll try to clarify the cams for you.
The 210 is the old Comp Cams 604 grind, excellent camshaft for the street, not for boost but handles nitrous just fine. Really needs a converter to realize it's potential. It has a powerband that is noticable from 2800 to 6000. Peak shift points are at 5500.
The 210X is the same cam but ground on a 110 lobe and installed at 106 degrees to produce more overlap and stronger torque at 2800-3500. It will handle spray just fine, not for boost. With the same converter it will ET or 60' better than the 210. I would have put this cam on a 108 if the vac had not been below 10" in a 360. I'll venture even the new 206X which is on a 108 lobe center/104 install, will scramble the old 210 out of the hole.
What can I say about the 220? It loves spray, boost, ill-prepped 408's, you name it. In a 318, you'll need a 2800 converter. I made 435 rear wheel on a 318 with 9lbs of boost and the 360 with boost will make 470-490 rear wheel. It makes 330 rear wheel on a 360 but the torque is only 320 naturally aspirated. It comes on at 3000 rpm like a spray button. But you need converter and gears to use it.
I would suggest the 210X with your mods and 300-310 rear wheel on the 318 is easy, with the mods you have. I posted some new info on the site and am finishing a article that explains lobe centers as the power producer in a cam, not the duration. Cam manufactures try to make you think you need more duration and spread the lobes out to 114 to regain idle and drivability. Not true at all, it's all cam politics. Less duration and optimal lobe centers, around 110-108, is the better choice. But that is another story....later!

Wow! Thanks for the awesome infor KRC tech, I will be ordering one of your 210x cams in the near future, in hopes to get my truck into the low 14's since I seem to be stuck at 14.8.
Thank you!

I have considered also buying a new cam for my 360 but have not decided which would be the best. I have headers, dual exhaust, ported Throttle body, flashed cpu, and accel ignition system. I am not concerned so much with high RPM Hp most of my applications involve pulling and a need for Torque in a big way. That is the reason i have not yet purchased an M1 manifold. I was wondering what cam grind and seperation should i be looking at for towing and pulling applications. I had an RV cam in an older truck that worked well but KRC tech if your still out there or anyone for that matter i would appreciate some advice. Thank you

Marty's the man on the cams-- but I have a funky cam that I running from Crower (custom grind)-- that would be nice to have ANOTHER person try it out and give me some feedback on it- Crower will make it a part number with a few more people's runs.
It's a good bottom end, excellent midrange, good time end cam. Not a screamer- I went with Marty's 1.92 RT heads non-ported, Crower 1.7s (that I already had)-- it's a .512/512 cam on the 1.6s... 208/204 (shorter on the exhaust than the intake, your rear that right). A 111 CL I believe. Not sure on all the other specs. Crower said it would build peak HP at 5500 rpm (again, not a screamer)... they were wrong. It built peak HP at 5450 rpm... hehe Peak torque at 3800 rpm. I am putting down 290 hp, and 325 torque (before the heads/cam, I was at 256 & 304 torque. Before the M1 I was at 240 hp & 325 torque-- That's a 4bbl M1, now switching to a 2bbl M1 to dyno those figures. Should put me in the 295 hp range, but in the 360 torque range.
(all figures rear wheel).
This cam would probably be a good runner on a set of stock heads too-- I sold one already to a guy to try out-- but he hasn't installed it yet.
So far I love it on the street, and NA... and it responds even better on a 100 shot! (108.4 mph / 12.622 sec. 1/4 mi)
