 Subject: 318 camshafts
IP: Logged
Message:
Hey, I just found the cam card in my basemen this evening and was amazed to see the specs on it. I put it in blindly because my machinist told me it would make some massive power for the street. I've got a 318(swapped) 95 dak 9.5:1 compression KB aluminum pistons, cam, p&p tb, cat and muffler, msd, electric fans.
Comp Cams grind # crs262hr-12
Intake Exhaust
.480 .512 lift
262 264 duration at .006 tappet lift
206 210 duration at .050
112 lobe separation
108 intake centerline
I don't know about the centerline and separation, but it seems to me that 480 and 512 is a helluva lot of lift for a street motor.
What do you guys think about this? should the cam go, or should I change my intake or get headers to help out with air/fuel flow?
Thanks, Geoff

That's a sweet cam for a 318. I think you'll be happy with it. It's definitely not too much cam for a daily driver. Have fun.

That should be fine! I do not start getting hesitant until I hit 272@.550 and above in a small block for street use. Once you get to .282 and above you will normaly get raw gas flowing out the tail pipes.

Thanks for the info guys. It's still kind of strange the way this truck drives, I think the v-6 I pulled out was faster untill 4500 rpms at that point my v8 will outrun a z-28 That doesn't help to much though, because my stock pcm cuts it out at 5200. I just started my freshman year of college, so I can't afford a mp computer for my truck.
I did have a set of headers on my v6 which helped out quite a bit and I haven't found a set for my 8 thats under $500.
Thanks again

You need headers. You should be able to get Gibson's for around $325 or so. That's what I'm running in my '95 318 truck.

A lot of people have told me that the stock exhaust manifolds flow pretty well. I believe they are from a 96 ram which isn't as good as the 93 or so but still not too bad. Should I do headers before an intake manifold or PCM?
I just started looking for a job here on campus so hopefully I can start doing some more mods to the dak in the next few months.

In order, I would do the PCM, the exhaust, and then the intake manifold. Your stock PCM is probably having trouble coping with a bigger cam. You've already helped the intake side with an air intake and a throttle body. Do the headers first to open up the exhaust side a little more, then an M-1 intake.

I agree, that the pcm would help out with higher fuel flow and advance the timing, but my cam didn't effect the vaccum at all. I hooked the engine up to a Snap-On scope in my shop class last year. The scope included a vaccum wavefore that showed it at a consistent 18"hg at idle. My teacher was really surprised and how much there was because of the work I did to the motor.
I also checked the ignition waveform just for fun, it was pretty cool. You could see the 4 consecutive spark plug firings because of the MSD ignition. I thought it would have been one consecutive spark but either way, my fuel economy went up.
I'm not sure what I said about the air intake, but all I did was put on a 6" open air element on top of the tb eliminating the factory cool air intake. This made a noticable increase in power when the engine is cold, but I think that when it warms up it is a bit slower.
Where can I find a PCM for a reasonable price? I used to work for a dealer, but I quit when school started so I no longer have my employee discount on MP parts.
Well, that's all I have for now so any other advice is appreciated.

The PCM is a P5249545 for a 95 318 auto. Earnhardt Dodge has it for $234.
www.parts4mymopar.com
That's the best price I've seen from a vendor I've never heard anything bad about.
I am running a Ram 360 computer on my 318 and it seems to like it. It works fine and by running the Ram pcm, you get even more advance. That's a P5249546 for a 95 360 Auto.

What do the rest of you think about a 360 a/t ram pcm? Does it use the same wiring harness?
Thanks for the tip and the link, i'll look into that
