Degreeing it in relation to the crankshaft centerline?

live4soccer7

I would assume that it may mean to the stock intake and exhaust centerlines, but have no idea what cam is in there to begin with. I have some markings I recorded off the cam in an above post if anyone can help identify them.

Maybe I'm following exactly.. But what are you trying to achieve/determine here? Are you trying to troubleshoot your static compression or just "dial" in the cam?

If you're trying to degree the cam to get it to "factory" setting, I'd suggest finding when the intake and exhaust open and close @ .050" along with the other information you've posted, and perhaps ping folks like Engnbldr, LCE, DOA and see if those numbers look similar to anything they offer or whatnot.. If you can locate who's cam, then I'm sure they'll provide you the proper index card to allow you to dial it in to factory specs. Hopefully that made sense.. I'll probably have to edit that once I read it..

I'm trying to dial in the cam, first and foremost at this moment.

Seems that I need to know the cam in order to get this done properly. Any idea on how to find that out? Grr... should of build the dang engine myself, then it would have been done correctly from day 1, but I tried to save some $$.

The lob separation angle of the came is 110.5 degrees. What else can I do to help find out which cam this is?

These markings were all found separately on the camshaft:

cwc
ep-32
G-9
D-2
C-2
I.5

Some quick searching yielded:

Take a look at those threads, and I think that should arm you with enough info to start making some inquires

Thanks... I'll take a read through them after I'm done working. I talked with the guy over here that did the machining on the engine (didn't think it had round/dome top pistons dang there goes my even higher compression I was hoping for), unfortunately he didn't put the entire engine together, so that didn't help much. He thought maybe the cam could be from delta, so I called them and they mark their cams on the cam face right behind the cam gear. I'm going to go ahead and take that off and see if there is anything there. Hopefully it will give me a url/website to go to ha ha jk.... Maybe the lift duration or a model number, something more specific than the numbers i have posted already.

If I have to take the head off and the cylinders are all good along with the bearings etc, I may consider getting some round top pistons to bump the comp. one and for all to its max and then seal this thing back up after all else is in check.

We will see when I take the cam gear off. I will then give them a call and see if I can't get this thing dialed in. If i had this info I think it would be smooth sailing from that point forward. So would zeroing in the cam mean setting it to the cam's factory settings for the intake/exhaust lobe centers? I am beginning to think this is what that has to mean and then from there go and advance or retard the cam. Ultimately, you would think with the 20r/22r setup it would be off because of the differences, but putting it back on track would allow it to run properly/correctly. Let me know what you think of that theory.

Ok well I took the cam gear off and found there were two yellow paint dots and a set of numbers 00 946. Any ideas anyone?

live4soccer7

Well, went to do the leakdown test and I don't have the right adapter for the spark plug hole. Will have to see if I can go get one at napa tomorrow.

live4soccer7

Got some new NGK spark plugs today while I was out at napa picking up that part for the leakdown test and managed to clean up my timing chain cover. Should have some results tomorrow and will redo the cam measurements as well. Should be a productive day, hopefully full of good news as well.

live4soccer7

leakdown test went surprising well with a leak of 7-11 percent on all cylinders on the cold engine. I put the TC cover, oil pump assembly, and oil pan back on last night. One quick question though. The dots on the oil pump assembly drive gear and other parts, do these line up? Seems nearly impossible with them pointing away from you when assembly. I did my best to get them to line up, but it doesn't seem they would have to be. Anyways, that would put me at rest if I knew the answer to that. The FSM just said reassemble it and that's all, no mention of the dots.

I checked the lift on the cam and it is .413". What is considered a high lift where I would need to begin to check for valve to piston clearance, valve to valve, and spring?

I have the engine back together and running. I have ran it and the pinging is now gone with the cam 2.5 degrees advanced. I have compared this cam and its specs to some over at LC engineering and the overlap simply sucks. I think I'm losing a lot with the cam I have installed. I have an overlap of 5 degrees, which means the scavenging is at a minimal. LC's mild cam has an overlap of 13 degrees. It is what it is for the time being.

I am going to move onto jetting my 32/36 b/c i can't get it tuned properly and from the info I've read it means that I'm running to lean. Won't idle at all with the idle speed screw at 1-1.5 turns in and the mixture screw at 2.25 turns out or with a 1/2 turn of it. I can't even screw it out far enough for it to idle. I think I'm going to go with a performance jet kit from redline so I have some jets to work with.

Correct me if I'm wrong, but there are 3 different types of jets, right? main jets, air jets, and idle jets?

Anyone know what the stock 32/36 DGEV jets are? I've done some searching and can't seem to find them.

JustDSM

I don't have experience with that carb (yet), but I'm sure Redline will be able and willing to answer your question on what jets typically ship with that unit.
