I have been a huge pain in the azz and I appreciate the great service. Chip arrived today and plan to get track data as soon as it opens. If anyone remembers, Jesse was kind enough to do a free burn for me after my lovely bride tossed mine in the trash. Before installing it in the new 406, it blew up due to faulty machine work. Did not have a chance to use the chip. Then i rebuilt the 383 and he burned it again New 383 blew up, again due to faulty machine work. I rebuilt the 406 and, you guessed it, lost it on the dyno. After sweepin up the garage floor, I cobbled together my best pieces. I did not have the nerve to ask for another burn. He insisted I send it. Thank you!

Sounds like he is a stand up guy, and you need a new machine shop, man i would be hot.
It did figure it out. The rod bolts and main studs were installed, torqued and machine work was done. The problem was the threads were not rolled in. When you torque the rod bolt down with fresh new threads, there is excessive friction. After cycling them 5 times, the threads "roll in". Then when they are retorque to the same spec, they clamp harder because you are effectively overtorquing them, by comparison to the initial torque. This makes the rod end or main caps smaller. Always roll in new threads at least 5 times. This includes head bolts or studs. Learned an expensive lesson.

Congrats for a free chip from ski, now my 383 is almost complete and soon will be at ur door, little scare of this darn thing, but i know its going in good hands.
My chip is sitting in a box right now ready to go with his address on it. I'm sending it out next week. I've read NOTHING but VERY, VERY good things about Jesse here on the forum (both his conduct AND his burns) and he's been kind enough to answer several of my question in PM.
I'm more than happy to give a stand up guy like that my business

No worries sami. We will screw it together, sprinkle holy water on it, cross the fingers and beat the hell out of it. It will be fine

That was nice of him, I'm sure he felt as bad for your series of misfortunes as I and everyones do, hearing of it. Glad to hear you've figured it out and it's behind you now. And to Ski...
Pete, You have had some terrible experiences over the last year. I don't know how you manage to stay above it all. I admire your determination and additude, and hope this is your year. You certainly deserve a run of good luck this time around.
Jesse, is a good guy and has fielded questions from me on several occasions and was always very helpfull Thanks. I am sure he understood what you have been going through,
Yes I had a good tune by Jessy on my 383 but over the winter I went to a superram and a FAST system so I can play my self. It was nice to have the help to get started.
Take Care

Hmm I haven't heard of that phenomenah. What brand rod, and main cap bolts did you use? I use ARP almost exclusively and have never had an issue. I use a stretch gauge to tighten the rod bolts or nuts down, as it is the most accurate way to tighten the fastener down. I have never had a failure of a fastener when torqued in that manner. Good luck on your new engine.

The rolling in was per arp. The stretch wiil change the 3rd or 4th time a brand new fastener is tightened. As the threads wear in to each other, friction is reduced. Then the finished id of the hole gets smaller as a result of the excessive stretch. My former machinest did not own a stretch guage. All good machine shops will(or should) cycle a brand new fastener 3x. Most will do 5x. Then machine the rod or main saddles. It took me a month trying to figure it out. My guy thought once torqued, machined and out the door was fine. He does not even use the arp lube. He uses 10 40 oil
For the record, if he used oil, lube, spit or whatever, and cycled the bolts 3x before machining, I would have been fine. Because it was a stroker, I had to mock up and disassemble a few times to check and fix minor clearance (block) issues. The final assemble made all of my finished bores .001 too small, consistantly.
Pete your scaring me about this bolt stretch and torque and everything My 383 is still on the engine stand waiting for the Heads to come back from the porter. I put a ton of money into this build and only bought the very best parts money could buy. If this thing blows up on me during fire up or soon after i'll commit suicide. Maybe I better go over that bottom end before it gets buttoned up Pipe

If the machinist did his job, it "should" be fine. Ask him how many times he cycled the bolts before machining. Also ask him how he torqued them. If he used, for example, 10w-40 oil and torqued to 50 ft lbs, you want to duplicate it. If he did not cycle, or roll in the threads, check the tolerences with a bore guage. If they are out of round and smaller than they should be, he did not roll them in. Remember, this only applies to brand new bolts.
THanks for the props. I have been a long time supporter of the forum here and always try to offer the best "Real Life" advice to you guys as possible. I have learned a TON through trial and error and openly try to share these experiences as much as possible.
Recently I have been working with Exotic Muscle on a joint venture and in addition recently became a supporting vendor here on the forum. I have had met many very supportive people through the years here and hope to continue contributing in a meaningful way through both my experiences and also through offering these tunes to people.
Most all the people I have done tunes for have become what I call very good friends of mine, Pete is just one example of this.
I look forward to working with many others here on the forum and working with others to achieve their goals.
Pete, you have had some pretty crappy luck over the last year, but we had a blast at the track last season. There should be another one of them coming up real soon; so get your stuff together and get ready to tear it up!
