Valve clearance Adjustment (I\'m so sorry....)

**I realized after careful inspection, that they are most definately hydraulic lifters..... /forums/images/graemlins/eek.gif /forums/images/graemlins/ignore.gif**

I'm putting a 305 chev engine (basically stock; edelbrock intake) into a 1/2 ton chev and am wondering what kind of valve lash I should set it to. (yes, it is mechanical lifters /forums/images/graemlins/grin.gif) Thx for the help. /forums/images/graemlins/truck.gif
 
Re: Valve clearance Adjustment

I would guesstimate, .008 for the intake's, and .016 for the exhaust's. /forums/images/graemlins/eek.gif

Maybe I should just stick to answering 33" tire fitment posts /forums/images/graemlins/rolleyes.gif/forums/images/graemlins/rotfl.gif
 
Re: Valve clearance Adjustment

Yes, I have a book giving me the technique so thats all good ! I just needed to know the correct settings. Thx guys.
 
Re: Valve clearance Adjustment

That is the procedure for hydraulic lifter cams. He has a mechanical lifter cam, and the procedure is different and uses feeler gauges. As for the settings, it depends on the cam and lifter used. That is something you would have to get from the manufacturer. Most (comp cams, crane, crower, etc.) list specs on their website if you know the cam number.
It's a PITA (adjustment and readjustmentS), but on a Hi-Po motor that is going to see some heavy REV's mechanical is the way to go.
 
Re: Valve clearance Adjustment

Why are you running a mechanical lifter cam on a stock 305. I don't think it will gain you anything over a hydraulic one. The lash should be set around 0.018-0.022. The manufacture of the cam should be able to tell you. It should also be on the cam card that came with the cam.
 
Re: Valve clearance Adjustment

OK I get it now. He said a 'pretty much stock 305' so I thought it was the other kind. Thanks for clearing that up. /forums/images/graemlins/thumb.gif
 
Re: Valve clearance Adjustment

I didn't pay attention as to whether it was a 289, 305, 350, or 572, mild, built, blown, running or not. All I concentrated on was the fact it was a mechanical lifter cam, as that was only thing he was asking about. /forums/images/graemlins/thumb.gif If he tries the method you described on his motor, he could do some serious damage and/or have a poorly running motor (valve(s) never fully closing, or hitting a piston). I just wanted to make the clarification before any damage was done.

Re: Valve clearance Adjustment

I bought mechanical lifters for it cause they were cheaper! /forums/images/graemlins/crazy.gif Its a stock grind cam and i'm not sure of the company who makes it.... /forums/images/graemlins/confused.gif Well which is it? intake .008 exhaust .012 OR both between .018 and .022 ???
 
Re: Valve clearance Adjustment

Call the cam Manufacturer, or it just might be in the Spec. sheet for the cam. /forums/images/graemlins/eek.gif
 
Re: Valve clearance Adjustment

Are you SURE its mechanical? They are hard to find and hydraulic cam kits are CHEAP ($100 w/ lifters)

What do the lifters look like. Where did you order it from?

If you have a mechanical cam you will not be happy because you will need to reset the valve lash every 5000 miles or so /forums/images/graemlins/frown.gif
 
Re: Valve clearance Adjustment

If you have a stock grind cam most likely it is a hydraulic cam. You DO NOT want to run solid lifters on this cam. On mechanical cams there is a lash ramp built into the cam to compensate for the lash. Hydraulic cams do not have this. If the lifters you have are spring loaded they are hydraulic. I would get the correct lifters for the cam you have.
 
Re: Valve clearance Adjustment

Well, they are solid lifters. The thing is, the guy sold me the cam and lifters together so I'm thinking they'll be fine together. /forums/images/graemlins/crazy.gifI just need to know how many thousandths of an inch to set it to. Somebody must know?

Why don't you ask the guy you baught the cam from. He should know the settings. He should also know what cam it is and then you can ask the manufacturer. If that dose not work, I am running mine at .022 lash on the intake and exhaust. Hope this helps.
 
Valve clearance Adjustment (my mistake sorry!)

I must apologize, I have made an error. I went and looked a little closer. What do you know! Hydraulic lifters! I got them all adjusted now so thx for your help even if I'm dumb. /forums/images/graemlins/1zhelp.gif
 
Re: Valve clearance Adjustment (my mistake sorry!)

No prob. We all make mistakes. Good luck with the new cam.
