If you keep going on w/ that vibration problem it'll be your own mistake out of your own wallet. If you would've met me before building that engine I would've told you, just like Z-rated when he was PM'ing me questions to do your research. Ask as many questions as you can to get as much knowledge as you can. POSITIVELY knowing how your engine was balanced is one of those pretty important things. Hopefully you'll have enough sense not to start the engine again until you can bolt up a zero balanced flywheel in hopes that'll solve your problems since you only have the "they were pretty sure..." incline to go on...
All I can say is good luck to you. Those are good numbers and hopefully you'll benefit from them.
If I were to ignore my last two sentences, hurry up and post a dyno sheet before I was ready I'd be doing the same thing which I see a lot of members here do regarding "bad" this or "bad" that. Think about that for a quick second. Just to ease your troubled mind over your ever-so-ongoing obssession w/ my application I probably won't be able to get it dyno tuned and to the track until November.

 

I know what you mean. It took the better part of a whole summer to figure out my problems after the h/c install. Went from a sad 13.10 to a so so 12.60. Then down to a 12.12 which still might be improved on slightly before the nitrous.

SSrrr, from what I remember, you didn't have much to say about my thoughts on trying to build a better y-pipe, other then to "do a search". And I do believe I gave you a little insite on what might be tried to gain a little more clearance with your TA tunnel brace with the last pm I sent you. Glad to hear it's almost time for some dyno and track times. I'm sure that car will haul the mail. Good luck to you too.

 

I apologize for sounding like a jerk SS RRR. Believe me I called numerous shops for help and most of the time I got "we don't do lt1's anymore" or "why would you do an lt1". The car will not run until the flywheel and clutch are balanced. I know how important it is to fix this problem. As stated earlier I tried several times to get info and straight answers from speed inc and never got them. That's why another post of mine here and ls1tech asked if speed inc does internal or external balancing on there strokers. If the balancer and clutch don't help then I'll probably be ordering another shortblock. This time from lme more than likely. Once thanks for all the help. I've got pics of how far I took the car apart, its my sig. Check them out.

 

Those are damn good numbers...Just as SSRRR said, just make sure you get the right answers from the engine builder and the proper flywheel and you should be fine...Your dyno numbers are much higher than mine, fyi...That thing should fly...If you were to get another builder to do an LT1 it'd be worth every penny to go with Lingenfelter, though...My Lingenfelter motor is almost on its 13th year of flawless performance...

Thanks ABA383 I've got the le2 kit with the le 3.2 cam and I had him do the intake as well. I followed his recommendations on eveything. I also have kooks stepped headers, electric waterpump, 58 mm tb, dynaspark, 30 svo's which le said would be fine others say there to small, racetronics boost-a-pump, kooks y, and a tsp rumbler. I didn't do duals becuase I lowered the car. All this through a 6 speed, a 4" aluminum driveshaft, and a 3.42 10 bolt. After I get this vibration fixed I'm gotta to buy a rearend. You outta check out the pics, just click the sig.

 

Post some negative feedback in the LS1tech sponsor section stating that speedinc won't even tell you if your engine was internally or externally ballanced, it shoud spark them to answer your question.

 

Yea I thought about doing that, I've had them ship the wrong parts(ie. ordered comp pro magnum rockers got some other brand, and they sent me the wrong asp balancer) and each time I called them about the problem and told them they needed to fix it and send me the right parts they told me they would call me back and never did. It's a shame because I spent alot of money with them and feel like it wasn't enough to get them to fix there mistakes. Oh well when I finish this car and start redoing the ss I will spend the $24,000 on the turbo motor I want with someone else.

 

Did it ever occur to you that perhaps the reason why I said that is due to the very fact I have absolutely no first hand experience on "how to build a better y-pipe?" I might have even told you in that PM that I didn't have any experience or that I didn't have the foggiest idea. That isn't what I was referring to anyway. And yes.. the information in which you volunteered to PM me which I didn't ask for regarding a T/A cross brace could not be used with my T/A. Mudsling much?
I'd be a jerk. I'd be pissed off as hell that those retards couldn't give you a straight answer. What I mean by asking questions is getting with as many machine shops as possible. There are more than just the "well known interweb" shops that can build a LT1 short block. As speed_demon said you need to make this **** public and see what happens. See how many leg humping jackasses come out of the wood work to try and defend a shop that cannot answer a simple god damned question regarding a short block THEY built.
Good luck to you.

 

Shiekss, sorry to hear your not getting the response from Speed Inc, that you deserve. I have better luck, but do deal with them face to face, since I'm only 15 min. away.

SSRRR, I was only looking for an opinion on the thoughts I had for a better y merge and different size I pipe and cut-out. With all your experience that you share with the rest of the board I thought you might have an idea or other options to see some gains. And I'm sorry if the thought I had about your clearance issues was not what you where looking for. My mistake. Take care.

 

I haven't a clue. You were told this therefore there's no reason to use it as some sort of ammo.

 

I had the same problems with that shop. They are absolutely terrible about it.

I ordered a canton pan and pick up through them, but their website only listed the old (unrevised) part number. I called them up and spoke with a guy for 15 minutes about what I wanted. He said go on the website order it, and he would change the order and get the right (revised) part to me.

When the pan came, it wasn't even an LT1 pan. Right on their order it was for a first gen nova or something (kick outs all wrong). I called up pissed off because they had wasted so much of my time. They informed me that they would ship me a new one only after I mailed the wrong part back and paid shipping to them and back to me for the new part!!!

I've dealt with virtually every sponsor/4th gen shop there is and Speed Inc is on my list to never do business with again. Terrible service, terrible employee's and gerneral d!ck heads. $70ish down the drain in combined shipping of oil pans.

 

Please be more specific. Who did you speak with, what was the specific issue, dates and times? Its easy to rattle off "they didnt do this or that" but it does nothing to aid to a resolution.

Also, forgive us, as the motor was purchased early 2006 - its not like we just shipped it out last month. Most of them all internally balanced and I see no reason why it wouldn't have been. As stated in the thread taking the weight off the flywheel would have been necessary and the longer the motor is ran in that condition the more it will tear itself apart. Also it would be a recommendation to speak with Larry the person who spec'd out the motor to begin with and worked with you on the sale as he is the most familiar with it.

I'm sorry that Canton delivered the wrong product. We have no reason to even order or stock anything for a nova. You are more than welcome to come over to the shop if you are in the area. We have 30+ latemodel performance cars here at any time. Most of them are f-bodies. I don't recall your order specifically, I might not have even known about the problems personally. If you have a moment send me your info and I'll look into it. I'll see if there is anything I can do to get you that money back. Not many places have 100% free shipping, normal policy is that returns have to be shipped pre-paid as we already ate the shipping outgoing. REGARDLESS if we (or canton) made a mistake it should have been taken care of properly.

 

I appreciate the offer, but at this point I'd just assume leave the issue as a learning experience for myself. I could bring up more detail/facts, but it was almost 2 years ago now. Thanks for the offer though.

 

A lot has changed in 2 years. None of the sales staff is the same, the shipping department and warehouse is totally different. Really besides the occasional parts mixup we rarely have any complaints in regards to mail order business. We have expanded our next day shipping range by using various couriers and doubled the amount of inventory we keep on hand as well. We have tried to weed out some of the slow or problematic manufacturers and still offer a wide selection of products.

Think about the offer - I'm not going to go back on it.

EDIT: I forgot to mention, problems were not common back years ago - but we took measures to prevent them from happening.

 

To prevent from Hijacking this thread too much, I sent you a PM. I don't care to get anything out of this, I just don't want you to think I am throwing out wild claims.
