Got my LS3 427 today!!
Original poster, the motor looks good. Good luck with the build, looks great.
Thanks man, I appreciate it. Yea I agree, I'm a bit confused with that post too. What is a PAS kit? I dont know either.

The claim that most 427s are 4.125 x 4.00 is not correct unless you are talking about LS7s. Most stroker 427s are exactly what this one is. The alternative is a sleeved LS2 block which is a great option as well, but more $.
BTW, if his headers clear the knock sensors where they are, there is absolutely nothing wrong with them. If they don't clear, you drill out and tap the lower hole where the stock LS2 sensors would go.

I don't think there's much concern about the APS kit either considering they have been MIA for quite some time now. There's always concessions with any build, it looks like the original poster didn't have to make many.

I had these SLP headers for almost about 2 years. Hopefully, they clear but if not, I make sure the above mentioned will get done.

Surprisingly, I don't think the location of the knock sensors is all that critical. I ran them off the back of the heads at one point and they worked fine.
They are now on the sides of the block and function exactly the same.

Yea i didn't think it would be a problem. I'm kinda thinking about that 10 bolt I have. When I first did gear swap mod, I got the richmond install kit and a TA girdle with stud kit. So I got this 10 bolt setup the best way I could without dumping alot of money into it. Maybe it should hold up for awhile. Sometimes I use MT drag radials but no slicks. I dont beat up and race my car at the track. In fact, prior to this build I took my car to the track twice. It ran 12.5s consistently. Maybe the 10 bolt will hold up maybe not. I think I will go with a driveshaft safety loop just in case.

Wow that ceta should scream! I'm envious.
And just for a clarification CETA usually stands for Collector Edition Trans Am not Commemorate Edition.

yes Alchemist, i know they cant go in the valley anymore. lol. i have a LS3 block. mine are drilled and tapped in the LS2 location. they need to get it so LS1 computers work with the stock LS2 style. they are small. lol.

As for the APS kits, I know that there were quite a few unhappy people here with cooked turbos from APS and they stopped giving customer support saying they were no longer making them. I didn't realize that they still had 50 kits they were looking to sell.
You learn something new every day, hence why I browse this section every day. I'm about a year out on my gen 4 400+ cube build, so I want to learn as much as I can before I pull the trigger.
My bad, hence why I said I wasn't certain. I didn't realize that there were two different locations on the bottom of the block to install them.

oh if you have problems with the knock sensor clearing you can run the ls3 knock sensor racetronix sells the adapter/extension harness to run ls3 knock sensors on a ls1 harness,
