Nice Kern, that's a tiny bit bigger than my 318 cam
I'm getting close to switching to a roller cam in the big block!

It is interesting how the link bar attaches. The lifter to the right has a simple round hole where the link bar is connected.
The lifter on the left …. The link bar has an oval slot to it to keep the lifters in line but allow vertical travel.
Todays delivery also included spring shims….
Sized at .015, .030 and .060, this will help me get to the correct installed spring height.
I’ve never checked that before. I get to learn a few new things here.
It will be at least a month before I jump in to do this. Feel free to pop in and comment, I’m sure not going to pretend that I have this all figured out on my own.

We’re going to need a cost round up when done.
Spreadsheet with breakdown and part numbers used.
Greg....for the record, a spreadsheet is not a picnic blanket that you and a girl sit on after a light snack.

When I do a major change and write about it, I am honest about what the costs are. I'll be sure to do that here as well.
Yes I did.....I have one of those melonized units from Hughes Engines.
Spreadsheets....
I've heard the "office type" people speak the term but I never paid much attention to the meaning of it.
I make lists with parts and prices....I'm not a complicated guy.

any particular reason for using Comp Cams?

For one, they really are the 800 lb gorilla in the aftermarket cam business. Dwayne Porter works with them and I trust his advice.
Hawk Rod has a cam of similar spec in his Road Runner, he is quite happy with it and it makes great power.
I can't entirely blame Comp for the 2006 failures I had with the 2 Comp Cams that I lost that year. In retrospect, every cam manufacturer was seeing an uptick in failures, a large percentage of them due to the oil formulas changing for reduced emissions. I used regular oil with the Comp pour in supplement for break in. During break in, the car ran hot so I shut it down about 15 minutes in. After a cool down, the car wouldn't get any spark so I wound up cranking on it a bit until I swapped in another distributor to run it another 15 minutes. THAT may have increased the risk of early failure. I was advised back then that my existing springs would be fine.....maybe they were, maybe not?
Just know that I am doing this by the book. I'm following all guidelines and procedures. If these parts and products are of high quality, I'll be fine.
IF there is a failure, I will post about it and deal with the fallout.

I have a thick stack of receipts.... i don't add them up.. i have at least 10k into a car worth 10k... that i paid 10k for to start with....
Yeah, but you have a big, $hitty grin on your face when you drive it. Isn't that why we do this???
Kern,
A couple of random things I thought of when looking through your posts:
1) When you go to install your roller lifters, soak them in break in oil for 24 hours or more to really get that oil well into the rollers. The rollers MUST be lubes well prior to startup. When the lifters are done soaking, simply put the oil in the engine for use during startup.
2) Make sure your shims are hardened: the shim that touches your spring needs to be a hardened shim, otherwise it will likely distort and get beat up by the action of the spring. Your spring pressure shouldn't be high enough to do too much damage, but an ounce of prevention...
