Also, I hope you were not charged extra for: "water pump was replaced, new coil was put in, a new optispark...new timing chain and gears". All of these items should have came off to do the cam swap so it was no extra effort to put on the new parts. Maybe not the coil, but give me a break, removing a couple of wires and bolts shouldn't really be an extra charge when you're already giving $1000 for a cam install.
It was like $1000 for the install of the cam kit, then they got me some new gaskets, silicone, 5 qts of oil, a dyno.....and all plug wires changed. All in all I think I got a good price. All the stuff that went bad might've been an extra half hour or so of labor, because all the bad parts were off anyways.

I put on the LT4 extreme timing chain and sprocket.

Well, the dyno went up to 5700 I think. The mechanic who was working on my car just hopped in and dynoed it. Looking at the graphs, it looks like it's going up with the RPMs so it might've been a little higher at 6000. With the tune, LT4 KM and airfoil I'm dynoing again.

You still didn't say why you had to replace the timing cover. I'm not trying to upset you for any reason, I'm just curious as to why they said you had the wrong timing cover. I would be suspicious of any shop that started taking parts off of my car(which was running fine) and then gave me a list as long as my arm of parts that were needing replaced. In the original post, your reason that the opti and waterpump needed replacement was that they had oil on them. I find it hard to believe that you strapped your car on a dyno on Saturday with no noticable problems, but then your optispark, water pump, and coil went bad between the time it came off of the dyno on Saturday until the parts were removed on Monday.

95TA8280 posts about his experience and hoping to get some helpful feedback and you jump over every detail he posts???? The timing cover was fine, he meant to say timing chain and gears, Damn, give him a break so he called it wrong. If your water pump had 80000 miles on it and was seeping coolant out of the weep hole in the bottom you would install it back in your motor because it was "still functional"? I do not think most F-Body owners would. No extra charge for wires? I guess you can replace a set of LT1 plug wires back into the original looms in zero time! I am impressed!

Dean =

Sorry about mixing up what parts I got, I left the shopping list at home and now I'm at school. Dean and the boys at New England Dyno Tuning did an amazing job with my car. Plug wires were changed because they had 80K on them and I'm assuming they've never been changed before. As he said, the water pump was leaking oil so I'm assuming that it had to be replaced, especially when it was taken off. The coil had corrosion in it....I'm not a master mechanic but I THINK thats a bad thing.... For anyone here trying to flame the people who installed I have never heard a bad word about NEDT from anyone (especially in the New England forum.....) so I certainly do not regret taking it to them.

As far 95CamaroZ-28 goes, maybe you should take a look at my previous dyno graph. You can search my posts if you want, it's there. It was VERY bumpy and a lot of people were wondering why that was. After the cam was put in, it ran a lot smoother. Everyone is saying that I'm not hitting as much power as I should, and that might be because it wasn't dyno'ed till 6200 RPMs...not the end of the world because I will be attending another dyno day at NEDT because they are great over there. My car ran like a new car after I picked it up. This thread started with helpful feedback and somehow got out of hand. Thanks to everyone who helped in the beginning.......And especially thanks to Dean and the boys at NEDT for their great work...I will certainly be a returning customer.

Dean, take it easy, I'm not jumping on the original poster. I just read what was posted and seen that he was told that he had the wrong timing cover and was just curious as to the reason behind him being told that. I (as well as others that replied to this thread) think $1000 for a cam install is a bit steep, and I was hoping that the guy wasn't told he had to spend money on unnecessary parts and labor. Also, I never once said that he shouldn't have been charged for the plug wires. If you will go back and read my previous post, you will see that I removed the wires from the list of parts I was talking about when I posted the quote. The parts I listed had to be removed for the cam swap minus the coil. I am aware of how time consuming working on a LT-1 can be.

I was unaware that you had previous problems with the car, my mistake. My stress level has been quite high for the past few days and I appologize if I came across as a jerk. I just don't care for shops due to so many people I have seen get ripped off. After reading the first post, I thought you had been taken for a ride. Now that things have been cleared up, I see that the parts were needed. That still doesn't justify the steep labor charges. From your reply, it sounds like they do good work. I guess you get what you pay for. Anyhow, congrats on the gain and I hope you reach your 330rwhp goal.

Dan, i dont think you have any idea how time consuming it is to work on one of these cars at all. Just becuase it takes you 5 days to put spark plug wires on a lt1 back in the factory looms doesn't mean it takes everyone else. 95CamaroZ-28 is not flaming the guy at all. Just seems to me to be looking out for the him. not to say that he needs it. But damn lay off.

My post was a little on the harsh side also - my apoligies also and I appreciate yours! On the cam swap -- we charge 10 hours for a cam swap only. At our present rates that is $650.00 Can it be found for less -- of course - can it be found for more - of course. But for the most part in this industry you get what you pay for, though I agree there are a lot of shops where you do get a lot less than you bargained for. I checked out your pics also -- sweet car you have there - good luck with it!
Check out the following links for pics of my motor, and some other LT1's we are presently working on:

For the work performed it isn't all that bad. and the Cutomer is happy. The customer isn't breaking down the cost and time correctly. He is doing it from memory, he left the sheet at home.


Hot Cam install
new plugs and wires routed correctly
Heads freshened up (Valve seals, springs, new Rockers.
Dyno time after cam swap.

The heads alone took some time to do, it all adds up.

The car had a massive intake leak, it was leaking real bad, the opti spark was covered in oil and coolant, thats why the optispark was replaced and the waterpump was replaced.
Parts weren't replaced for no reason.

The car actually had 2 sets of wires in it, one set of wire still in the looms and one set tie wraped to the looms, previous owner or some other shop had replaced the wires in the car and couldn't get the wires out of the looms (or didn't feel like taking them out) had just cut the ends off and left them there.

There were a lot of littke issues witht the car that were taken care of.

The car was put back together better than it came into the shop, and we make sure its done right the first time, so the customer can enjoy the car and not come back with problems.

Rob

Yeah, I sent the computer off to be programed for all my mods. I dont have but ordered an adjustable fuel pressure regulator...I dont know if that will help. The car runs good when its cold....well better, but as soon as it warms up it start shaking and if I slam the throttle from a dead stop it kind of back fires. The worst is when I'm cruising at 55 to 70 mph in overdrive. When I get into the gas it shakes real bad and eventually kicks down into a lower gear. It sucks I can't figure it out.
