Good Cam Profile for a 482?

[Rick Parker]

Morgan: To eliminate constant valve train maintenence and inspections, (and problems!) look for a cam with about 238-242 intake duration @.050 and about .570 lift. The rollercams with higher lift and longer duration put extreme loads on the rocker arms and their pivot points/shafts that they were not designed for. And things can happen.......

Red and Rick,

That cam is the same one Keith installed in my Pond 482 last February. I have put just under 500 miles on it this summer sorting things out. One of my requests when purchasing the motor was that I did NOT want to be dealing with those things under the valve covers! I was told at that time, that I would need to adjust, and re torque, the valve train initially, but should not have to mess with it after that. I need to check a few things with them in regards to this anyways, so I will ask about future needs again, to clarify.

Brad,

We have the same motor. This past month I had two lifter adjusters break. Some bent valves and push rods. Just trying to determine the cause and attempting to prevent the same thing from occurring. I am not placing blame on Keith. The adjusters themselves are suspect and will be replaced out with ones from T&D which are superior. The heads are now at Keith Craft for rebuild. He did not intially build up the edlebrock heads, this was done by Trans Am Racing in Gardena CA.

Morgan,

I'm sorry to here of your troubles! Keith used Erson roller rockers on his stage two heads, and supplied everything from the oil pan to the carb on my build. I'm pretty much done driving until next spring, so I'll be checking things out here soon. If changes need to be made, to sure things up, now would be the time. I am also going to change the oil pan, as there is no windage or traps in mine. I had not planed on any road course action, but I see now it might be hard to stay away.


Kevin,

Things are a bit choppy down low until the motor comes up to temp. Once it's up to temp, it will idle at 800 rpm all day, with a nice lope, and rolls thru the gears, at low rpm, with no effort. I chose a .64 TKO 600, with a 3.50 rear, and in 5th gear at 60 mph it lugs, at 70 it smooths out, and at 75-80 it's cruisin' at just over 2000 rpm. It's all good as far as I'm concerned.

Morgan,

I spoke with Keith this AM, and discussed the valve train maintenance with this set-up. It is a good idea after a few hundred miles or so, not a must, but if you want to, you can retorque the intake, heads (not as critical), rocker studs and 1/2 turn preload on the lifters. Doing this on a cold engine is fine, and once you do this once at the beginning, and you will not need to do it again.

He is done rebuilding my heads. 1 day turn around, which is extremely rare these days. Sending me a new cam and lifter to replace the damaged cam and lifter. Should be back in business before the end of November.

Did you stay with the same cam?
