I'll just wait until I gather everything to take to my buddies house. He has all the proper tools to do it right.

You can always make your own intake manifolds. These manifolds have a 35mm ID to match the modified 35mm ID intake port in the head.

Hey everyone,

I have some updates. After a long waiting period I'm finally building this thing. Its in longblock form currently. Should be done and in within a week or two.

Here are the parts going into this thing. There are probably more I'm forgetting. Feel free to ask.

- Stock crank
- Stock flywheel
- Stock clutch
- HD pressure plate
- Scat C25 cam
- Scat lifters
- CB oil pump/filter cover
- Rotating assembly dynamically balanced
- 92mm thick walled cylinders/pistons by AA
- Rebushed OEM rods
- Single port heads ported/polished
- Windage pushrod tubes
- Weber ICT's (Jetted 60 idles??, 140 mains??)
- Port matched CB single port manifolds
- HD single springs
- Chromoly keepers/retainers
- Solid shaft rocker shafts
- Stock rockers
- Chromoly Pushrods

The deck height ended up being about -0.005 to -0.010. I'm going to go pick up some .060 cylinder shims today to fix this. Heads are cc'd to about 50-55cc's So I should get a compression ratio between 8.1:1 and 8.7:1

-Josh

0,040 shims would be plenty! and better.

JRKman · Posted: Thu Sep 18, 2014 9:47 am Post subject:

Wouldnt that give me a deck hight of 0.030 possibly? Which would be 9.3:1 for the compression for the C25. Wouldnt I run into valve clearance issues here?

I'll get a video of it for sure.

How does the jetting sound for the ICT's?

60 Idle, 140 Mains. Should be able to start it up for break in on these jets I'm thinking.

Your engine looks great,and just like my 1955cc singleport. Your 60 idles and 140 jets sound perfect. I think you will be close with that setup.

Runs great. Just took it on a 400 mile trip to Jerome for the jamboree. Pulled the hills better than i hoped. Got excellent gas mileage.

So I went to set the endplay today. Just pushing/pulling the flywheel I get .010" with no shims. If I slightly rotate while i push/pull I get between .035/.045

What measurement am I supposed to go by? .010" seems a little tight with no shims...

Engines installed and broken in. Can't get it to idle right now with the ict's (60/140 jets). Gonna have to work on that. The idle speed screws want to be over 3 turns out. Thoughts?

I see you switched carbs to Kadrons. Crank trigger + 019?
