Can you degree any cam for a LT1? And what is necessary to degree a cam? Do you have to have an electric water pump or a double roller timing chain?

I just wonder if my car problems are due to timing and the cam not being degreed in.

I guess I'd ask whast your problems are?

I believe many/most cams are designed to provide the correct degrees when they are installed straight up with the timing dots. I.e, if you have a cam designed to provide 4 Deg.advanced timing, that if you install it correctly, you will get 4 Deg. advance.

I understand that it is important to have a correctly degreed cam, however, I didn't know that it was a modern-day problem.JMHO

 

Comp Cams website has complete instructions.

Checking is the easiest (but not easy if engine is in the car) procedure, but adjusting it is the problem. You need adjustable cam drive parts, which aren't that easy on a LT1.

I agree with BUBBA.

What are the problems and what are engine specs. That's a good place to start.

Lots of times problems are either improper installation or a bad choice of cam timing rather than improper degreeing. Not saying this is your case, but it does happen.

 

I thought that you couldn't manually adjust the timing on cams in LT1s because it throws the computer off. I believe you have to have the timing changes ground in. Is this correct?

 

Never heard of anyone degreeing their cams on this site.

 

Here are and were the problems.

I had a compression test done last week. I had 0 compression on cylinder #1. Come to find out I had a RR set to tight holding the valve open. We reset all the RR's and did another compression test and everything was ok. The car still seems to have a miss somewhere. It backfires some at high RPMS. I have starting problems. The plugs n wires have been changed. I thought it may be the opti but I had the car SCOPED and the only miss I had was on cylinder number one due to no compression. I havent taken the timing cover off to see if the dots were lined up correctly but they shouldve been. This is just really frusturating.

 

I assume that you pre loaded your RRs correctly.

 

And...how about your FP? SB around stock, unless your programmer compensated for something other than around 45-47 at WOT.

Just some thoughts.

 

FP is ok. What is SB???

Im thinking the timing may be off. I have no clue at this point. Its just pissing me off.

 

SB=Should Be.

Good luck.

 

Thanks man! I need it.

You disagree with that, and from a person who has degreed cams, I agree with you.

Well, you certainly could have, you've been around long enuf. It HAS been discussed B4.

As also stated, your routine/typical sbc cam timing adjustment options are complicated by the LTX platform.

Although, in this case, I believe the problem source is elsewhere.

 

Thanks people!
