New SCU 4.3 engine pics

Thought you guys might like to see some pictures of the new motor that Dave just finished building for my 91. Only thing that changed from the pictures is the head allignment dowels, they were cut to allow for expansion of the heads, in an effort to prevent them from lifting.

What did you keep from the old one? Looks like its all new. Are the rockers the same? they look different. then your standard RR.

I kept the late model timing cover, oil pump, BHJ balancer and the rocker covers....everything else is new. The rockers are something new that Dave has recently developed to allow increasing the rpms without the loss of valve train stability. All I can really tell you, is they look to be way stronger than anything else I've ever seen on SC head.

Well the man can build an engine. Good luck of course and let us see some results so we can all ooh and ahh appropriately :D In fact I want to be green with envy over this build! ;) :D

Ira :D
 
It was a very nice piece to look at last weekend :D. The rocker setup that was develeped is very nice and well engineered. Good to see you made it back, and can't wait to hear the results.

This is the third mention of people cutting the dowels that I have come across the past month. Which way are they cut and how are they aligned/inserted into the block? I am at a point where I could do that too, but just need some clarification. I am assuming half moon with flat edge facing center of the block?

Ryan,

Nice seeing you again. Sorry I was a little groggy from being up till 4:30 the night before and didn't recognize you. I thought you looked real familiar and asked Dave who you were shortly after you left. After he told me I felt like a real jerk for not saying anything.

David,
Looks good! Is the cam the same spec as before?
I take it Kurt and Chris will over this weekend helping.

Ken

Ken,

Bigger cam and higher ratio rockers on this one. I haven't asked either one of those guys to help yet, but I'm hoping at least one of them is avalible. I'll be out of town the next weekend, then the following weekend is Easter...so I need to at least get the motor sitting in the car this weekend, then I can do the rest of the stuff as time allows in the evenings after work.

Correct...but only the portion sticking out of the block is cut.

No problem, the both of you looked beat, and I could tell that you were not looking forward to the trip back. I'll catch up with you in May.
