I'm thinking speed density. Reason's: I'm in Florida. Therefore no change in altitude. little change in temp(apr 30* swing) and use of any induction setup. Does this make sense? Also there are other pistons besides Wesco. pistons that run right to 0 deck for 4.1 stroke. There are members here running tons of nitrios 4.1. They run with 4l80e and spools though.
I will look into other brands of pistons but referenced the Wiseco's since they are what is listed for this build. I like Wiseco's so I was wondering if the deck height issue had been addressed.

First off, when are you going to call me? Second, I don't think you have anything to worry about when it comes to your nitrous tuning skills. I have no bigger dream than a 4.185" x 4.00" stroke solid roller motor in any LSX platform I happen to own at the time. But I am very curious about the bore to stroke ratio and nitrous use since I hate not having the fastest of what ever platform I happen to be driving at the time. So the plan for the V1 CTS-V for the moment is a 427/429 LS3 with a 250shot. We have a pretty good nitrous guy at the shop and I plan on tapping your brain as well. I know I can build a N/A motor and can make well over 600rw N/A on motor but with the extra stroke and thin piston crown I have to go with what Brian Nutter suggests for his pistons and not go over a 150 shot on his 6.125" x 4.125" pistons. 850rw on the bottle is the only way I can make this pig competitive from a roll. I don't plan on digging this thing with the glass rear end GM decided to put into the V1 V's. Unfortunately I don't do this every day like some guys do so I can't answer my own questions. Fortunately we have amazing sponsors and very technically savvy people on here that do. So PLEASE, Martin, Brian, someone, give us the info we need. Inquiring minds want to know.

The Wiseco 1.050 compression height pistons have a .250 top land and .150 2nd land. We've had some customers hit other pistons we make with those land thicknesses with 300 plus, but the critical thing is the intake pocket to groove thickness. Our 1.050 pistons accommodate LS7 and Cathedral heads and have deep pockets for long cam durations. If a guy called and wanted to hit it with 400, I'd say we could probably do that; but would prefer to do a dedicated custom where the valve pocket depth could be raised (and moved away from the bore in the Cathedral case). Customs take a little longer, but the extra $ isn't that bad considering...especially in the case of "shelf stock with 1 change" custom pricing offered by some piston companies. Also, 6.098 rods are commonly available and that .027" worth of ring land would be nice. Hope this helps.

Thanks for the response Brian. It is nice to hear it from the manufactures mouth. So if I am doing a 4.070" x 4.125" 427 how much bottle could I run? Are the 4.125" x 6.125" pistons limited to a 150 shot as stated on some Vendors web sites? I would like to some day build the above and be able to spray a 250 shot. I am guessing this piston was a custom or the deck was milled to fit.

Brian,
I need to get with you on some projects we have here.
Do you have a direct email I can reach you at by chance? It would be nice to have a direct link with someone like yourself regarding our engine builds.
Seeing as we ALWAYS use Wiseco....

Goosecaddy05 and Pray... I know of a company that i dont believe is on this site, but their rep told me they were dropping prices on their V CTSV 9 inch kit 1k dollars around holiday time yet he never updated the website.... go with the 9 and trash the 8.8. just wait until next winter. PM me if you want to talk about it... i am no such vendor for the company though, just a little birdie looking for a V1 CTSV myself.
And im sure youll have no trouble grenading a stock V1 diff even rolling into it with 800+ rwhp. Nitrous hits pretty hard and is unforgiving.

I believe the owner of this motor is a member on here and honestly I think I know the member name....... I pay very close attention to what people say on each thread. I bet a 100 dollars the car is a black 2000 SS.

Well let's just say I know a me member on here that had a 404ci LS2 and he part it out. Later told me that he was having a 445 ci built by late model engines. It's not everyday you come across a guy say I'm doing a 445ci motor. It's not yet popular 408 if you know what I mean....... The member name is close to black00SS

just curious, at the cost of an aluminum 5.3 core, sleeves, labor/install/machine etc. wouldnt it have been the same price just to go with an lsx block?

i no this is a old thread but for the last couple of days i been calling about getting a block resleeved with 4.125x4.125 and they say stay 4.00 stroke for nos because piston crown.then looking at this what has been done to this motor that he can spray that much nos on this size stroke,
