I ordered thru ATECH (Summit) and mine was here in 2 days. It was the 425LS3, as Im planning on running our New Red Hot cam package.

I got the mod kit, ididit, headers and entropy radiator from them. All great looking parts. Talk to Chuck on that wait time though, hopefully they've caught up, but I waited around 20 weeks for mine.

The jet-hot coating probably isn't needed, but it will definitely cut the under hood temps way down. I had a set done on a C5 vette and the difference between mine and another car was very noticeable! I'll do the same with the ones I got for the Nova too.

When I spoke with him he said 12-14 weeks build time. He mentioned his welder had been out sick. I’m in no hurry as I’m an accountant and tax season is about a month out. I’ll be pretty busy so it will be late April before I have time for it. I’m on the fence on the coating. He pretty much said it was a waste of money, but I know a coating can cool things down. I’m thinking I’ll get them in and see how I feel about it after some driving. If I need to I can pull them and send them out.

Most likely there will be additional cost for prepping "used headers" rather than new. FYI

 

[Chevyman1979]

That’s ok. Im going to run them and if I change my mind I’ll bite the bullet.
What do you all think about thE below booster and master? I want power brakes and this looks like it fits the bill.

I did the 430 LS3 from PACE and installed a BTR cam if you buy the long block you can change a couple things to your liking

 

[showdog75]

December 2020 price was $500. That included about $100 shipping and insurance.

Before paying that much for jet hot the OP should look into Zycoat. Latest greatest polymer coating.

 

[Bob's 65 Post]

When I got my headers from CBR I bought the non-coated version. Then sent them to Jet-Hot for their ceramic coating. If I had to do again I would check to see if they could have been sent to Jet-Hot first and then to me, would have saved one of the shipping charges. At today's shipping coast that could be worth looking into.

My headers have couple thousand miles on them and still look Great. FYI contact I dealt with is Brian Richardson 800-432-3379

Approximately what does it cost for ceramic coating? Sounds like a good option. Edit: Nevermind I saw price in conversation😂

Called Chuck today and bought the 1 7/8 headers along with the Ricks tank and a set of rear Viking shocks. Real cool guy and he was happy to answer all my questions.
The ls3 had the upgraded cam to make it 495 hp. I’m not sure the exact specs on it but it’s their crate engine that is sold at summit etc.
I told him I am considering the rear mini tub and 4 link in the future and he said I could ship the car to them and they would install it all. I may take them up on it when I get to that point.
I have the clutch and Bellhousing bolted up. I dial indicated parallel and concentric and was all in spec with the QuickTime Bellhousing. No offset dowls which is nice. I went with a McLeod rst twin. Seems to be a good street clutch.

Make sure to have the car tuned after you install the cam.

 

[Chevyman1979]

Cam is already in the engine. I’m running a terminator x kit. It should tune itself. I’ve had good luck with the system.

 

[Chevyman1979]

Im considering doing the trunion upgrade on the ls3. Just watched a video online of the install and it looks fairly straightforward. I will have to check how to retorque them when I reinstall. I don’t know how necessary this upgrade is but I have heard the bearings can destroy the engine.

 

[Chevyman1979]

What do you guys think of the below?
Seems like a good way to adjust and simple. The grunion kit is fair priced as well.

I thought only the LS7 heads had that problem. Is this something new?

 

[Chevyman1979]

It appears any of the stock LS engines can have the issue particularly with a larger cam. I feel like it’s cheap insurance just in case.

 

[Chevyman1979]

I started the tear down. It appears the radiator support is riveted to the subframe.

Grind - Drill the heads and pop them out "That's Normal"

 

[mc1984ss]

You are correct, there are 4. Some people grind them off some drill them. I drilled mine

 

[mc1984ss]

The middle is bigger around than you think!

 

[Chevyman1979]

I’m probably replacing the core support with an aluminum support, so I’m thinking of leaving it attached and pull the whole thing together. I hate grinding rivets.

 

[Chevyman1979]

Just ordered the below core support. The guy was was really outgoing and knowledgeable. He said the core support is very nice and he has more in stock. He’s also planning to raise his price so if you’re in the market I would recommend picking one up now.
