Unforgiven Project

I have WAY to much time on my hands this week. And that is not always good because It gives me time to second guess choices I have made.

Example: My cam choice has been bothering me, It's a flat tappet hydraulic 243 /.541 intake and 253/ .565 exhaust. Duration at .050...

If you do the math you will see that I am below the 47.5% rule.... I came up with 44.7% which may mean trouble.

Second issue is that Scat 9000 crank. I will be switching it out for either a Callies (if I can afford it) or a Molnar next fall for sure.

Third...I have a set of Erson horizontal solid roller lifters waiting on the shelf.. Using these means new springs,locks, retainers, pushrods,and of coarse the cam. Easily $1200

I could prolly swing the cam swap...but I feel the crank should be my first concern.

Had I have known at the begining of this project that I would have this much cash invested, I would have went with a big block . It is what it is at this point.

These are some of my thoughts that give me anxiety attacks while I have too much time ... I hate second guessing!

I just need to get this engine on the dyno and find out how close Rick's software is to the dyno. I find that to be exciting.

I am kinda worried about the aggressiveness the cam ramps are though.

Maybe I should just switch to decaf ! :confused::rolleyes:
 
HAHAHA !! Me and the Mason jar are VERY good friends!
I am down to a 1/2 jar of the clear which is my favorite... And about the same with some blackberry. Not a fan of the blackberry. At least not the recipe that was used.
We will be hanging out together tonight though!!
 
Where did Grumpy and Rick go?
Seems like all my rowdy friends have settled down....( or got booted) :(

Anyway.... I would like to thank Grumpy for a gift idea I got , from a post he posted on another thread!!!

I asked my wife if she would wear these

OR... If she would prefer the boots below

She said she liked the first ones better..... cause she felt she would look silly flagging the truck races wearing ONLY the boots in the second pic.
And that I would have to buy the whole outfit to make those boots work. :cool::cool::cool:
And she did not want me to spend that much money on an outfit anyway.


Well.... It was a hard decision NOT to buy the whole outfit for her...so I ended up purchasing the boots below..

They still set me back the cost of a carburetor though... :eek::eek::)

Anyway Thanks for the idea Grumpy!!

Don't know about Grumpy, but I'm still here just occupied with other projects.

Still working on the headers, I'm on to version 5 now.

Also trying to learn some new software called
Fusion 360 by Autodesk. I offered to do some 3D modeling for Larry Meaux of Pipemax and when I
went to install 3DS Max 2010 that I own, Autodesk quit supporting that version so I could not get
an activation code, that's about $3000 of useless software I have now. Kinda leaves me in bind. I don't
know if Larry is going to take me up on my offer, but I wanted to have some idea how I could complete
the project if he comes back to me. He did say maybe in a couple of weeks when I asked for flange
dimensions and anything else he could supply to help me.

Larry went thru my Pipemax file and made some changes and really help me, so I am trying to return
the favor.

I'm also working about 15 hours a week.

Not on any of your backup discs with the code in a folder?


You are now working too many hours to be retired. They will use you up if you let them. Soon you will be working 30-40 hours if you don't watch them.

Yes I have saved my previous codes, but it's different when you install on a different computer
or even when you change hardware on the same computer.

I'll keep an eye on them! So far I have actually cut back on the number of hours. My boss said he
would loose 19 days of vacation this year, yet he has given me days off every time I ask, including
the week of Christmas. But I always show up on time and almost always come in when he needs
me to cover for someone that doesn't come in as expected.

That is worth alot to employers now days. DEPENDABILITY!!!
Something that seems to have gotten lost with SOME of the younger generation..
But... I am happy to report that I do know of a few younger guys who retain the attitude of hard work and dependability.
And a couple would give you the shirt off their back if it was needed.
All is not lost..... yet
 
Rick.. I haven't commented on your header thread cause what you are doing is WAY over my head.
I find it very cool that you can use and understand the software stuff.
 
Thanks Unforgiven !

It's the software that makes it possible to do such calculations, all you have to do is put in the
time to make accurate measurements. The header builder should be able to take the output
dimensions and make a header for you. To get the most out of Pipemax you need a dyno output,
I used Dynomation instead. Pipemax needs to know the RPM for peak TQ,HP, BSFC ...etc .
Dynomation was better than no dyno numbers.
 
I purchased an engine cradle for transporting the engine to the dyno. It fit very nice. I was amazed at how sturdy the cradle was with the engine mounted. I am going to test fire the engine on this mount before I head off for the dyno (just in case). I also made up some aluminum angle brackets that are attached to the heads, for lifting the engine in and out of the bay. This way I do not have to remove the blower or EFI
in order to attach a lift plate on the manifold. My 4 lift chains where 2 links short so I had to add the eye hooks to the brackets. I have "s" hooks on my lift chains, so its. very quick and easy to hook up.
I was worried that once the engine was mounted to the cradle, the headers would not clear the floor. But as luck would have it....They cleared by about 6". Coty is stopping by this week with a pair of 3" flange mufflers. Being that my collectors are 3 1/2" , I am going to purchase a couple adaptors. This way I can make up a full exhaust so I can actually hear the engine itself, and correct anything if necessary . Hoping to fire it up this weekend.

I did have to clear the starter housing rib by about 1/16" to clear the rear mount post.
All in All I am happy so far with the cradle. Jegs had them on sale for under $30 , so I picked up one for me and two for coty.
 
I love the custom and highly functional addition of fabricated aluminum lift and eye bolt brackets
 
Nice planning on your part for the dyno!

Do eye bolts have any kind of rating or grade like normal fasteners?

you can buy lift eyes that are rated for over 1200 lbs :Dfor under $5 each threaded for 3/8 16 tpi nuts

common eye bolts are rated at near 150 lbs

Description
Take a look at the features for Ken Forging Eye Bolt. Material: Steel, Overall Length: 3.09 to 3.47", Thread Size: 3/8"-16.
 
Rick I am not sure about the load capacity.
I have both styles of eye bolts.
the ones on the motor are the open style.
They are made of stainless steel. I can get more info from the tag when I get back in the barn this Sunday.
I figured that the engine cannot weigh more than 8-900 lbs so 4 of them at 3/8" should be plenty to hold.
There where no signs of stress (opening up) when I lifted it of the stand and lowered it to the cradle.
