Help me sort my combo

-
Looks like your plan is a step (or 2 ) above everything I have planned. Bet you kick azz!
Thanks for the vote of confidence. I constantly worry about the direction I'm headed as this is my first project just learning as I go. If it wasn't for this forum though I tell you I would be completely flying blind, I sure appreciate any and all advise. Cheers FABO members!!!
 
If you are going to keep the manifolds then take a look at this article I wrote a long time ago. I tested a bunch of different cams in my car trying to find what worked the best with manifolds. It took a long time and cost a bunch of money.

Incredibly informative article, thanks Andy for going to the effort. Must be a dream job! With all the advice I've received I'm leaning toward the lunati cam 10230703. It looks like it will work without doing further machining, will match my springs and give me a wide under the curve band. I like the extra attention to the exhaust ramp, I hope it helps with the manifolds. I'm still gonna call Lunati and talk about my combo with them and see what their techs have to say.
 
If the engine is still in the car, get the timing set up correct. Will make a huge difference in how the car runs from bottom to top. THat cam love a TON of initial timing.Like 24-28* or more.

I have the 508/108 in a 340 with a 2500 converter and it's a difficult tune up. Distributor is locked out at 35* timing. Starts fine even when hot. Be much better if the converter wasn't so tight at idle in gear. I didn't build it and the 508 cam WOULD NOT have been my first choice! The car is getting the original 360 and a XE262 cam, IIRC, built back up and installed.

Don't call Lunati to ask about a cam for an engine with exhaust manifolds. They won't be able to really help you. There are very few people who know how to pick a cam for manifolds. Call Porter Racing Heads and talk to Dwayne. He does cams for the FAST guys so he knows how to cam an engine with manifolds.

Hey crackedback! Have you considered a looser converter? how about rear gearing? Is compression enough for 292 cam?

Was this the cause of needing to freshen the combo? I hear so much about wiping cam lobes out anymore, I am starting to have nightmares.
 
They don't have it all the way torn down yet. I found no metal in the oil filter. Hope its just the cam. Should know later this week.
 
Hoping its only the cam too there, fingers crossed... I am starting to think that the hi dollar Schubeck lifters with ceramic bases may be the way to go thanks to all the continual reformulation of oil to meet stricter emissions standards.
 
Or maybe to just give up and break the bank for a roller setup...
 
There is a guy who posts on youtube about his mopars. I think his name on youtube is dylan McCool i believe. He had a comp cam wipe lobes! He removed a perfectly good running 484 mopar cam. So he learned the hard way.
 
So what I want to know next is why. The good news is a new cam should make her really rock!
 
Stopped by the machine shop today. Looks like the only damage is the wiped cam lobes, thank God. Little bit of extra metal in the oil. Posting some pics of the cam asap.

I guess its a matter of interpretation........

To me, that’s a cam that’s “going away”.
It’s been in service quite a few years, right?

A cam with “wiped out” lobes is more like this:

In your first pic, you can see the wear pattern down near the base circle is wide and located in the center of the lobe.
That’s going to result in minimal, or no lifter rotation....... and one result of no rotation is what you see....... the nose of the lobe wearing away.
The corresponding lifter likely has little or no crown left to it.

The MP cams I’ve checked only had .001” lobe taper, whereas most all aftermarket performance cam grinders use .002” lobe taper, in an effort to promote better lifter rotation.

This is the second cam in this motor. It has maybe 2200 miles on it. The motor has about 2500 since rebuild in 1996. I really appreciate your experienced viewpoint, Dwayne. I am having a hard time verifying the cam specs. Any help out there?
 
I'm not seeing a wiped cam lobe. I see a wear pattern. Over and out.
 
The specs of the current cam are a moot point.
You’re getting something new, so what that one is doesn’t really matter.

You can measure the lobe lift of some good lobes, multiply by 1.5..... and whichever MP cam is closest to that lift, that should be what you have.
474, 484, 509, etc.

Did they measure how much lift is missing off that lobe?
I would check to see what the lobe taper was on that one with the wide centered pattern.

It should be in better condition than that with only 2200 miles.
What were you running for oil?
