Default Final Evo Build

After my second mishap with cranks I'm hoping this will be my last build for this motor. I won't be changing or modifying this build again and am confident it will last for a long long time.

I just picked up my motor yesterday from Hillside. Thanx Scott for taking time out of your personal time and meeting me on a Sunday to help me out. It was nice chatting with you again... Greatly appreciated. 600 miles round trip in 17 hours so I'm a little dopey today.

Anyways, started assembling the oil pump lines and filter mount. Lined up the motor to the trans with my Baker primary motor plate and got it all snugged down so the alignment is done. Tonight I'll be assembling the primary drive, charging system and starter. Once that's done I'll start assembling the rear head and adjust the pushrods setting the preload to .140" . Once that is done I'll be able to confirm my target compression of 10.3:1. (43* ivc). Special Cam I had Bob Wood grind for me...

J&E are the only piston manufacturer that could supply me with what I needed to get the motor up to 10.3:1. They are 30* angle top's and are .020" over bore putting the cylinder bore at 3.645". Couple that with my S&S 4 5/8” crank it's putting the displacement right at 96.5 cubic inches.... I'm pretty fortunate that the Cometic head gasket was just barley big enough for my bore....




For the heads, I had Scott supply me with a new set of heads that he worked up to stage III. A lot of the D shelf was remove to accommodate the 1.94" intake valve and a 1.65" exhaust. If you look closely you can see how the D shelf was also dished out for the Piston as well. With all the machining to the heads, the combustion chambers are now very big requiring the use of the 30* angle to pistons to get me to my target compression...








I didn't realize all the work that had to go into the heads to accommodate the 30* piston dome. Not only that, another thing I noticed was the small chamber around the entire combustion chamber, Scott said it was necessary and is precisely measured to get the proper combustion chamber size and will also aide in the fuel burn efficiency... and yes I did have compression releases installed... oh yes forgot to mention the AV&V valves and springs good to .650" of lift...

Check out the intake and exhaust ports, man this motor is going to breath well. He initially qouted 278 CFM... Not bad for a small block, eh?








I must say I'm really impressed with his work and am sure I'll be just as impressed with the power

I almost forgot to mention why I went this far with this build is because the left case main bearing sleeve was trashed due to a bad crank that was installed else where. Scott took care of the as well. He machined his own sleeve and mechanically fastened it to the case. Bullet proof now... I'm sure. Here's a couple pics of that as well..





That's about it for now I will update my progress as it goes....

Thanx again Scott.....

Default Nice work !

I knew Scott was good, but haven't used his services, yet.
God willing one day I will.
I owe him a solid. He gave me some info of what I was trying to machine & was good enough to tell me a trade secret. Stand up guy, in my book.
I like how he Dutch keyed the sleeve in.
I've sleeved many a housing bore , using that technique.
It ain't moving!
Hope it all works out for ya.

Ride Safe,
Harold

What intake manifold are you going to use? Did he port match the intake to the manifold for sealing? It looks amazing!

Yes he is. I've known him for quite some time now. I used to live up there. Nothing like cow country....

Yea, it's the S&S E intake. Everything was port matched to 1.80". Should breath rather well....
