Cam advance question.

yellow rose said
Why do you want to advance the cam? Don't make an assumption that it needs to be done.

Sad as it is, the April 2020 edition of Hot Rod magazine has an exellent article on cam timing. It's worth the read even if you have to go buy that rag.

Pay very close attention when the Comp guy is talking about "centering" the overlap "triangle".

I did not say I wanted to advance the cam. I asked if I needed a timing chain that would allow a cam to be advanced.

I think that cam is just right as is for what you're doing. No way would I use Rhoads lifters on it. I think I would also install it right where the cam card says.

Part of the reason for the Rhodes lifter was for "the hope for a good hydraulic lifter". I would use Johnson lifters... But that's only because Hughes sells them. (In all honestly I Believe hydraulic lifters are failing in performance situations because the spring load is too high. For instance I am going to run comp 901-16 springs instead of Hughes 1110. I gotta research more on that.

Cams should always be degreed in.

Forget about “advanced” or “retarded”.

Determine where you want the intake c/l to be..... and put it there.

For that cam, I’d shoot for an intake c/l of 106.

I don't have alot of money for this build.... I gotta do the work.

Degree it, and yes get a multiple key way timing chain, for example I installed a camshaft straight up did a compression test it was at 130 psi the camshaft was in at 110 advanced it 4 degrees went up to 150psi to 106 this is in an automatic car though pretty quick and gets 15mpg city driving with 3.55

an answer that was helpful with some real world numbers.

If you got both carbs try both.

I got both carbs. THIS MAN IS SO RIGHT WITH SIMPLE LOGIC!

budget rering smogger use the smaller carb
are the primaries the same size?
if one is smaller use the smaller
the cam is ground 4 degrees advanced
put it in where comp says to or a couple of degrees advanced- I think it is ground 110 so 106 sounds about right
remember it's an asymmetrical lobe so work from the .050 up from the base circle to find lca
lca measured from the top down each side will be retarded
that's why so many want to install really advanced
they have to do that just to get to the real ICL
Ask Comp
They're retarded
prove me wrong- it's my turn

I wish you would learn some punctuation. You seem to know wtf your talking about..... But I can't read your advice.
