Hey @Summitracing , these ever go on sale? https://www.summitracing.com/parts/nal-19432557

Any deals or coupons out there for those of us who can't find a shop worth a **** and have $13k of scrap under the hood of our C5s?

Or these and I can swap my own cam : https://www.summitracing.com/parts/n...2422?rrec=true

Actually I may sell the heads. I did find an old article on VMAX CNC'd LS3 heads which should be the same program as these L92's: https://www.lsenginediy.com/ultimate...r-heads-guide/

Scroll almost all the way down.

Let me know what you think for $$$. I need to open up the 408 and determine wtf, and if it's coming out, may as well put more power in it. This is the way

While it may be possible these could go on sale in the future there's no way to tell for sure if/when that would be. We try and have competitive pricing on all of the items that we carry. There are currently free shipping promotions on both of these long blocks. However, they aren't in stock and it looks like it could be a couple of months or longer before we will see any. As always we have our Beat-A-Price price match policy!

So are you gonna tell us what you think happened or...?

it lost oil pressure, the oil is gray and speckled and I am damn near positive it was knocking when I put load on the motor to get it into the garage

460mi after putting it back in, the second time lmao

At this point I am pretty fed up with this engine, and I have no idea what the issue is. I shimmed the pump, I have a pick up brace, I used the proper o ring and its obv seated in the pump properly. It may have pushed a galley plug or the cam retainer failed or the rear cover seal failed- but at this point I feel like it almost doesn't matter. I have 0 confidence in this motor and the shop that put the bottom end together. Its a lower comp motor for boost, so it basically makes cam'd LS3 power anyway, and I feel like everything I did here to get this motor into this car was a waste of effort

So, just buy an aluminum motor that was factory assembled and send it. How many LS3's make 450 at wheels? All of them lol

So, I have been beating this idea to death-

New LS3 long block much cheaper than used, for what you get; including peace of mind

Fixing the 408, while possible... leads me down the rabbit hole of "can I ever trust this thing again?

Used LS6 is about the price of an LS3. IF my cam is still good, I can swap it into the LS3 long block and basically party. I can also do a reluctor swap or converter box. With the bump in compression and less valve shrouding, my cam should make similar power in the smaller motor, and lose 30-50lbs of torque; which might be a good thing based on the car's ability to overwhelm the rear tires anyway lol

Looking like LS3 long block is what I will be pulling the trigger on. @Summitracing <3
