Those look like creampuff pistons?
I know all to well the feeling of this. Amazing what a little detonation can do.

Pretty minor damage in my opinion. I thought this was lucky!
Unlucky if you count the list of everything else that the car has required, but lucky in terms of being able to get it going with a gasket set and a new slug (if I wasn't beefing it up)

Just a quick update!
We dropped the engine off at the machine shop yesterday. They are going to be installing the new K1 Rods, and custom coated wiseco pistons.
I have Tony from JTSVP working on a custom grind cam that will be NASTY!
Slow bleed lifters, 1.7 ratio T&D rockers, new valve springs and a port and polish on the heads.
a 12psi pulley, and new tuning from Torrie at Unleashed Tuning and I might hear this beast run in 4-6 weeks!!! Getting excited now, other than we will likely have snow by then...

Yes, there are more minor details (timing set, aftermarket harmonic balancer, hardened pushrods, titanium retainers, TNT total seal file fit rings).
I am very excited, it's been a long overdue project to get back on the road and kick my Vette buddies asses!

I can't stress enough to look into rod bearing issues on these car. The more I've been looking into it, the more failures I see. Even gen 4's are falling.

I'm gonna be checking mine out within the next month. I'm pretty sure they will be wore out even after some of the mods I have done.  We shall see I guess.

Order the trap door oil pan kit from JonB right away.  Only takes about 15 min to install it.

Your ACR has an oil pressure bypass relief valve that Joel, John and I are looking for - Only came on ACRs  ...

Tell your engine builder to use Gen 4 bearings and machine the block as shown on this site.  Joel`crankshaft mod can be done in a couple hours and should make a difference as well. 

Who`s porting your heads?   Switch to Beehive valve springs.  Align hone your intake manifold for another 20-35whp (about $250).

Glad it`s finally happening.  Diamond or Ross forged pistons?

I have the new Total seal custom made ring set for std size forged pistons and will be sending them back unless you can use them.  Custom ordered for supercharger with stepped ring.  Also have a set of .15`raidial wall thickness Hastings rings new.

If you get desperate when assembling I do have a spare intake and exhaust gaskets and a set of head gaskets on my shelf.  If you use them you`ll need to replace them though  (My in stock parts).

What is required for this Joel?

I was looking into the gen 4 oilpan conversion. It's a higher capacity setup.
What is the advantage to using gen 4 bearings instead of what the engine "should" have?
The engine shop is porting the heads, they have a guy there, fully CNC certified etc.
The springs will be recommended by Tony, for what is required for the custom cam with .601 lift. The car already has "double" springs in it similar to the upgraded Roe springs we put in my SRT10. But I don't think they will handle that high of lift, so will get changed regardless.
I didn't want diamond pistons, I requested Wiseco pistons, that have the special coating on the skirts, and on the tops specific for boost and nitrous.
The rings are also special TNT rings as mentioned, for boost and nitrous. They also have a specific orientation for the same use.
The only concern, is the slow bleed lifters are hard to get right now, sean had 10 on the shelf I think, tony only had a few. A set of aftermarket race lifters are going to cost about 800-1000 bucks if I can't find mopar slow bleed. Either way, it needs done.
Getting excited, and really curious what it will put down for power with over double the boost, and a fully built motor.

You only need the gen 4 bearings if you do the gen4 block mod. Pic are on this site under the how to.

I have some used slow bleeds that I changed out last year just because. I'm sure they are still good.

Thanks Joel. The block mod is worth the time/money to do? It helps in oiling, or whats the scoop?
