Semi-DIY Mild Engine Build for FI

Ross when ATI mentioned that there system is rebuildable does this implies that their system is prone to failure as well? And how often and why would a ATI rebuild be warranted?

batman... the benifit in ati's pulley is vibration reducbtiom... plain and simple.

vibration and oil are the two major factors in loosing a motor or exsessive wear on parts
 
BATMANs I'm curious re: the 12-sided nuts in the photo of your big ends. I've not seen them before, what's their purpose? are they OEM? If they are some special kind of non release nut how do they work?

Yes, the big ends of the conrod are held on by 12 sided nuts ... what's the purpose of that unusual nut design? perhaps they have to be very highly torqued up?

I like the videos, especially the "watch your fingers" and "don't breath this" parts. Sounds like a pretty cool guy to let you video this too. Thanks again to both of you!

Fantastic videos. Admittedly, I cringed when he started cutting the valve seats. This guy works really fast! Holy crap. I'd be measuring 10x before I cut and probably still mess up. You can tell he's a craftsman.

Agree with Dave. Really cool he's letting you share his talent with the rest of us.

What a great thread and love the 80's background music in Post #278 lol

BATMANs - Sorry if I missed this.. but did you ever definitively figure out what was the cause of your engine failure?

He looks and acts like the scientist from back to the future. He makes and sells latex Halloween masks on the side.

Oh yea. He knows his stuff and moves so dam fast and can talk and narrate at the same time. He's been doing this for 45 years. Problem is that he is so good he had repeat customers diluting his time.

dunno the cause of engine failure but all ringlands popped.

Mt timesert kit came in so I'll drop it off this week at the machinist. Apparently, I was holding him up from doing the block decking, boring and honing since he wanted to do it after the Timeserts were installed.

The rotating assembly balance should be done, last I talked with him he said all of the weights had been figured out and he was ready to go.

Also, he did a pre-disassembly pressure test on the heads and said they were in excellent shape. I'm going to go ahead and have everything disassembled, valves measured, decarboned, cut, and polished. Then do the 3-angle cut, replace the guides, and then figure out what to do with the springs/retainers/seats.

I'll see if he can also do what Batmans did on sharpening the intake port divider walls. I'm going to hold off on the fancy head coatings though :smile:



Lesson to others contemplating doing engine rebuilds:

I should have gotten him all these parts BEFORE racing season started :redface: His racing customers, rightfully so, have priority. I'm in no hurry and just pleased that it's in good hands. Also, you may have some bargaining power on the machining prices too during the "off season." Of course, that really wasn't a concern since machining costs pale in comparison to the aftermarket parts prices :mad:

I'm a bit bummed that I wasn't able to get a video footage of the heads flowing.

But I did get a call that the numbers looked much better than an average head from my engine builder.

He said that he has the numbers and will type them up.

What he is looking for are the specs on the stock cams so that he can make sense of all the numbers from the head work. Anyone have them handy?

I'm suprised you've never used The Right Stuff. It's a must have for 13B oil pans.
