Hey all
Has anyone installed a cam and found the end where the timing gear slides on to be too long?
If I slide the cam fully forward up against the plate it sits in the perfect spot. If I slide it back it fouls up the lifters on the lobes as I have .230 end float. After having a look I found the new cam the be longer where the timing gear bolts on.
Anyone had this before. Do I need a spacer or machine the cam?
What end float should I have. I would have thought around .020 to .040 would be enough.
cheers Maca

What motor is it for ? Check the application. Magnum or LA

I'm lazy, this explains it.

Thanks for the info. I got it sorted.
I have had a look at the factory cam and now I understand where the end float comes from. I thought the spacer had to be an exact measurement to control the float.
But after looking at the factory cam the timing gear actually bolts hard up against the cam and the step that's machined into the cam is what controls the end float. So I put on a spacer and bolted up tight, I have .0025 play. Do you think this is enough

how about a history note. back in the late 60s i was using 392 HEMIs. and the cam had spacer on the nose of the cam. it was only .125" aprox. thick. so you had to move it to the new cam. a added note. the old 392 HEMI and the 354 HEMI / POLY the cam will go into ether block. BUT the lifter angle was different. i DOES pay to read.

Thanks Guys
So basically I don't have enough end float. Min on the comp cams install sheet is .005 and I have .0025
I know I should get more but I have put everything back on. I am very tempted to just run the .0025 as it is free and you can feel the float easily by moving the cam. I guess if I run it and its not enough I only have myself to blame.

I would have the cam plate ground thinner at a machine shop, you've got some expensive stuff there. Your call Greg.

Your right Dan, I should fix it. It's all together and I just want to get it finished.
When it warms up it may not have any free play I guess.

All done now. I shimmed it and ended up with .0055
After you reminded me about all the expensive gear in there I saw the light.
cheers
