I am building an lq9 bottom end with lsa heads and an ls3 intake and have a few questions.
1. Should I use the ls1 or ls2 style valley cover with the pvc system
2. what length pushrods do I need
3. Are the torque specs for the iron blocks the same as the ls1's
4. Does the ls3 fuel rail hookup the same as an ls1 or is there an adapter

Thanks. I'm sure there are more questions that I don't know about yet. But I searched and couldn't find much info on these.

1. I'd get the one with the pvc thing built into it.
2. Will be related to several factors. Measure then buy. At least see what the people making your cam suggest.
3.
4. Might be a bigger diameter (are all returnless the same size?) but same principle. I can't recall if I had to get a bigger fitting or not.

I'm sure someone can correct/ finish this

4. Yes, same exact connection. I've had good luck with the adapter made by Pure Choice Performance.
