how much n20 on a LSX 454? hey guys got a question for anyone who knows a little about LSX's. ok i want to build a LSX from GM and i am stuck between building a 427 or a 454. but i know i at least want to spray a 200 shot on the car. But i have heard the with a 454 you cannot spray that much. But if i go to a 427 will i still be able to make around 600rwhp n/a with a good set of heads?

What he said.....
We spray a 275 shot on the dyno, more at the track.
Like he said, keep it small towards the 430 range.
Don't know who would have said it won't take a big shot

What are you looking to do? A 434ci with a 300 shot will make about 900 RWHP.
I'm still up in the air what to do with my LSX iron block. Been researching everything. single turbo, sc'er and spray.
A 434ci with decent heads and intake should make 600-650 RWHP on pump gas...spray it with a 300 shot when needed....you'll be one of the fastest street cars in the country. It'll be a highway pulling monster. You'll be walking away from almost every big liter bike too. Unless they modded their bike quite a bit.

Keeping it to a 4" stroke is a good idea due to cylinder length (not the tall deck) so the 434 is a good way. 4.155 bore x 4" stroke
We actually just completed a nitrous build for a customer like this. LSX 434 built for a 400 shot. It is running a Wilson Bank Billet intake with direct port and plate wet kit for dual stages.
