    Need advice--Camshaft degree issue (maybe??)

    After I get the cam degreed properly I will be reviewing the rest of those items to verify all is good, and hopefully close to target. No matter what cam I were to put in this, I would be doing the same exact thing to make sure it is all good.

    Need advice--Camshaft degree issue (maybe??)

    This cam is ground with a lobe separation of 107 degrees, and you are to degree it in at 102 degrees. So the LSA-Cam Degree=5 degrees of advance built into the cam. If you add my stock gears with another 4....holy crap that is 9 degree total. So if I degree it within 1.5 degrees either side of...

    Need advice--Camshaft degree issue (maybe??)

    I said screw it, I am done effing with this thing, I called up Competition Products (where I bought my timing set I am using) and they happened to have a Cloyes double roller timing set, 9 keyways in the bottom gear, and 3 holes in the top gear!! NOW when this arrives I will get this dam thing...

    Dies when put into gear

    Out of curiosity sake, when the truck is idling will it rev up & down nicely when you ease slowly on the gas and let off? Now how about when you hit the gas harder, what does it do? Hitting the gas harder will put that quick load on the engine without it being in gear, so one would think it may...

    Well shit, went to comp cams to compare prices and used that part number......a different damned timing set is pictured here at comp. I already have this set..... https://www.compcams.com/magnum-double-row-timing-set-for-65-83-oldsmobile-260-455.html Not sure why summit would show a different...

    Need advice--Camshaft degree issue (maybe??)

    So close, yet so far! For the hell of it I put in my stock timing set, that came out to 98 degrees so it is 4 degrees advanced! I think what I should do instead of continually pissing around with this is buy another new gear/chain set that has more adjustment to it. Right now my lower sprocket...

    Need advice--Camshaft degree issue (maybe??)

    Ok, thought about this more. YES....I was setting my degree wheel back to 0 and starting over. Should I set the degree wheel to also be 4 degree advanced?? Then start the process? This is the first time I have ever degreed a cam before, so still learning here. Watched a whole bunch of youtube...

    Need advice--Camshaft degree issue (maybe??)

    Man, I am not sure on that one?? I have it back at stock setting now. Getting sick of re-doing the same damned thing over and over and getting the same effing results.

    Need advice--Camshaft degree issue (maybe??)

    @QBuff02 I believe I understand your method now, I did exactly what you suggested and ended up with the same result of TDC, and cam centerline of 105.5 degrees. So I am still off of 102 by 3.5 degrees. Shit. I adjusted my stop too, so I was matching 34 degrees each side of TDC by moving the...

    Need advice--Camshaft degree issue (maybe??)

    Ok, so bear with me here to be sure I understand this. Let's use the numbers I had (just for my sake :D ). When I did the positive stop in each direction, the two numbers added together & divided by 2 equaled 83. My degree wheel was sitting at 84 degrees. Now I have to go 83 degrees on the...

    Need advice--Camshaft degree issue (maybe??)

    @QBuff02 I took your words here & will reply.... Generally how I do it is I put the timing set on and then rotate the #1 piston up to tdc as close as I can by eye and then install the degree wheel and the makeshift pointer on tdc Yes, this is exactly what I did. i'd then back the piston...

    Need advice--Camshaft degree issue (maybe??)

    With my timing gear marks lined up (as pictured above) I set my degree wheel to TDC (I should have said this earlier!). I then rotated the engine to install my stop. Then I rotated the engine in each direction until it hit my stop & recorded the numbers. I added them two numbers together &...

    Need advice--Camshaft degree issue (maybe??)

    See my first post my friend :D (it was 97.5 degrees, so 4.5 degree advanced).

    Need advice--Camshaft degree issue (maybe??)

    @Blue Ox I am degreeing starting with TDC where my pointer is (coat hanger). What I did was make that positive stop a couple inches down the cylinder to roll the engine each direction, write my numbers down, add them & divide by two. With that result, I would then roll the engine back that...

    Need advice--Camshaft degree issue (maybe??)

    I am working on my '69 455 Olds right now, degreeing the camshaft on it. I need your advice on the results. Comp cams advice is "leave it as you have it and run it". The camshaft is supposed to be at 102 degrees and my results are not that. This is for my 76 GMC crew/dually, I will not be drag...

    I can't drive.....fifty fiiive

    @SquareRoot You put a 5 speed manual in this baby? I had to look up WTF you were talking about :D The google searched turned up cool stuff. I always thought a manual in my dually build would be sweet, maybe some other year though. I think that would be sweet to hear the 4-bbl's open up then slam...

    New engine break-in method

    The comp cams literature said NOT to prime the engine either, even for just their cam I am installing. Earlier engines I have built I did prime them, this 455 will be a first that I don't do that. I am also using the assembly lube on everything. They also stated to fill the oil filter so the...

    Cutting down valve guides & reusing head bolts??

    I guess it also pays to sometimes read the booklet stuff comes with! Take these new valve springs for instance, I installed all of them like I "thought" I was supposed to until another Hot Rod buddy of mine said "you should take out that inner spring to break in the cam"....so I read through the...

    Cutting down valve guides & reusing head bolts??

    I wonder what is different dimensionally between those W-30 heads and the C heads I have? Valve sizes, or port sizes, or both?

    What have you done to your square lately??

    I think they actually do weigh more than her!! These are the big valved C heads they used, man the ports on this thing are big too. The heads however do weigh a LOT!!

    What have you done to your square lately??

    We (our oldest and I) have been working on the 455 for the truck. Got in my new double roller chain and gears, a friend is going to loan me his degree wheel so I can degree the cam in properly for optimal performance out of it, heads are off, valves are lapped, valve guides cut down, heads...

    Cutting down valve guides & reusing head bolts??

    I found the engine ID information! Mine starts with 39X......so its Olds Division, 1969, made in Kansas. Last 6 digits should match the cars vin which the car is long gone.... Here is the site I found this information, great stuff!! https://oldsjunction.classicoldsmobile.com/oldsfaq/ofhed.htm

    Cutting down valve guides & reusing head bolts??

    Ok, I got some information off of my big block. It is a C style head, and the casting numbers are below. @Blue Ox These casting numbers found just above the center two exhaust ports.....on the left side mine was "394" and above the right port was "548" I also think you are right, the "D"...

    Cutting down valve guides & reusing head bolts??

    Well guys, check this out! This cutter and arbor worked amazing! Took me about 15 minutes to do all 16 of them, I took my time and ran the cutter slow as recommended by comp cams. What I did not know is this cutter also had another small cutter on it to do a chamfer on the top of the guides. I...

    Cutting down valve guides & reusing head bolts??

    @HotRodPC would have to answer that one, or another Olds expert! My dad has another 455 Olds in his shed, I should see what heads are on that one.....maybe it's the unicorn/legend one :D doubt it though.
