which is best

[pipsterls1]

i am thinking of tuning up my 5.7 ls1 for more power, i do off road racing with it and it is not street legal, whats the most power you can get from an ls1 and what would you all recommend.
or is it better just to buy an ls7
let me know your thoughts

It's a really open ended question. There are guys pushing 900hp out of an LS1, but it aint exactly stock. I'm a bit confused...

what exactly do you want from the car? Full out drag car? Auto x? All around? A bit more info would be helpful.

Yeah, you definitely need to give us more info before we can recommend anything.

Well if your doing off-road racing with it then you might want something reliable and something with lots of torque.

what kind of off-road racing are you talking about?

[pipsterls1]

thanks guys, the racing i am doing is a cross between ralling and corr racing it takes place through forrests and fields, lots of torque is a big addvantage and quick accelaration is most important i dont mind if its not staock but i would like the engine to be reliable and not need constant rebuilding, i am running a 4L80 auto box with shifter kit, the regular race lap/stage is between 8 and 12 miles.
if you need more info let me know
thanks for your intrest

Ah, and LS1 would be fine then. Even a stock bottom end with an aggressive heads/cam would put you in the 500 hp/tq at the flywheel range.

He would benefit from a 408 if he wants lots of torque.

how much money are you looking to spend? i would not go witht the ls7 by the way if you have 10k a stroked ls2 will get you good power with a nice heads cam intake setup. But built ls1 with a roots supercharger would give you awesome torque also.

I wouldn't look at the LS7 unless you just want bragging rights. You can build that much hp for about half what an LS7 crate costs. Look into the strokers as suggested.
